Boerhaavia diffusa is a medicinal plant widely used in the Ayurvedic medicine. Ayurveda is
an ancient traditional medical system of health care of the Veda civilization, flourishing inIndia many thousand years ago. The term AYURVEDA means Knowledge or Science of
Life (From Ayus meaning life and Veda meaning acquaintance, science) in
Sanskrit. In fact, Ayurveda focuses on the physical, spiritual and mental aspects of an
individual. The plant was named in honor of Hermann Boerhaave, a famous Dutch
physician of the 18th century (Chopra, 1969). B. diffusa (Spreading Hogweed in English)
belonging to the family of the Nyctaginaceae, is mainly diffused perennial herbaceous
creeping weed of India (known also under its traditional name as Punarnava). B. diffusa is
up to 1 m long or more, having spreading branches. The stem is prostrate, woody or
succulent, cylindrical, often purplish, hairy, and thickened at its nodes.
The last two decades witnessed an enormous research rush to reveal the pharmacological
actions of an annual spicy delicate and beautiful herb known by the Latin name Nigella
sativa Linnaeus (Black Caraway Oil) variety hispidula (brachyloba) that belongs to the
botanical family Ranunculaceae. The plant is an erect profusely branched herb that canattain heights of 40 and up to 70cm.

Cancer is the second most common cause of death after cardiovascular diseases (CVD) inmost developed and in many developing countries, including India. In this country, every
year around seven million new cases of cancer are being detected. The global burden of
cancer doubled during the last 30 years of the last century. In 2008, it is estimated that there
were over 12 million new cases of cancer diagnosed, 7 million deaths from cancer and 25
million persons alive with cancer within five years of diagnosis. The continued growth and
ageing of the worlds population has immediate consequences on the cancer burden. By
2030, it is estimated that there will be over 26 million incident cases of cancer
annually.(IARC-W.H.O. Report 2008). Lung, stomach, liver, colon and breast cancer cause
the most cancer deaths each year. About 30% of cancer deaths can be prevented. The change
may be started by external agents and inherited genetic factors. About 72% of all cancer
deaths in 2007 occurred in low- and middle-income countries. Deaths from cancer worldwide
are projected to continue rising, with an estimated 12 million deaths in 2030, (WHO-2010).

The 20th century saw unparalleled increases in life expectancy and a major shift in the causes
of illness and death throughout the world. A century ago, cardiovascular disease (CVD)accounted for fewer than 10% of all deaths; today, it accounts for approximately 30%
worldwide (Gaziano, T.A., 2005; Yusuf S. et al., 2001). The increase in CVD, through a
proliferation of risk factors that are heavily influenced by lifestyle choices, is the new
challenge for many developing countries. Cardiovascular diseases accounted for 16.7 million
or 29.2 % of the total global deaths in 2002, according to the World health report 2003,
around 80 % of deaths due to CVD took place in low- and middle-income countries. By 2010,
The contribution of developing countries to the global burden of CVD, in terms of disability-
adjusted life-years lost, was 2.8 times higher than that in developed countries (Reddy and
Yusuf, 1998). By 2020, about 42 % of the total deaths in India are projected to be due to
cardiovascular causes (Murray and Lopez, 1996). During the period 2000-2030, about 35 %
of all deaths due to CVD in India are projected to occur in the age group of 35-64 years
(Leeder et al., 2004).

Several lines of research have established that both CVD and most prominent ras growth
protein-induced cancers are coupled and controlled by a common mechanism involving the
up regulation of HMG-CoA reductase, the rate controlling enzyme in the cholesterol
biosynthetic pathway. In tumour cells, the feed-back mechanism at the level of HMG-CoA
reductase is flopped, resulting in a several fold increase in its activity and cholesterol
formation, which also results in hypercholesterolemia and subsequently CVD. Increased
HMG-CoA reductase activity in tumour cells is associated with unrestricted supply of
farnesyl pyrophosphates, for rapidly proliferating tumours.
We investigated the effect of aqueous ethanolic extract ofB. diffusa and Black Caraway Oilon DMBA-Induced carcinogenesis and hypercholesterolemia in animals which was not
studied earlier.

The proposed study designed to investigate both hypolipidemic and cancer chemotherapeutic
properties ofBoerhaavia Diffusa roots extracts and Black caraway Oil. Cardiovascular
diseases (CVD) are more killer then Cancer in the world. So, creates a need to develop a
simple and cost-effective methodology for the isolation and extraction of ethanolic roots of
B. diffusa (Bd) and Black Caraway Oil (BCO).
1. Phytochemical Screening ofB. diffusa (Bd) and Black Caraway Oil (BCO) using HPLC.
2. To estimate the effect of ethanolic extract ofB. diffusa (Bd) and Black Caraway Oil (BCO) in
the suppression of experimental carcinogenesis in rat liver and their impact on different
marker enzymes. Will be investigated carcinogen 7, 12-dimethylbenz [] anthracene
(DMBA), which is known to induce both carcinogenesis and hypercholesterolemia/CVD,
was used.
3. To correlate the efficacy ofB. diffusa (Bd) and Black Caraway Oil (BCO) extracts in
preventing the increase in plasma triglycerides (TG), total cholesterol (TC), VLDL-C, LDL-
C, small dense (sd)-LDL-C and large buoyant (lb)-LDL-C in hyperlipidemic rats.

4. In rats with DMBA induced carcinogenesis coupled with hypercholesterolemia, in addition of
Boerhaavia Diffusa and Black caraway Oil mediated anticancer impacts, anticholesterol
effects on plasma and lipoprotein lipids and HMG-CoA reductase activity will also be
investigated.
5. The role ofB. diffusa (Bd) and Black Caraway Oil (BCO) in the suppression of carcinogen-
induced cancer at pre- and post-initiation and progression stages will also be examined
histological in liver, kidney and pancreas. Thus, both hypercholesterolemia and
carcinogenesis mediate a sustained free radical load (Antioxidant power), which could
enhance lipid / lipoprotein peroxidation.

Animals
White male albino rats, weighing about 150-180 g were purchased from Indian Veterinary Research
Institute, Bareilly, India, were maintained to animal house under standard normal condition having natural
photoperiod (12 hours light/dark cycle) at temperature 2510C and 50-60% humidity. Animal
experimentation protocols conform to the Institutional Animal Ethics committees guidelines. The hairs on
dorsal skin of the animals in the interscapular area was shaved 3 days before the commencement of the
experiment and only those animals in the resting phase of the hair cycle were taken for the study, because
resting hair retains carcinogens for a longer period. The rats were sacrificed at sixth hour of dark cycle atthe peak of diurnal rhythm of HMG-CoA reductase (Edwards et al., 1977).
Diet
The rats were given pelleted rat chow and tap water ad libitum. Experimental rats from respective groups
were administrated with Boerhaavia diffusa (Bd) and Black Caraway Oil (BCO). Both Bd (1mg/ 1ml
methanol stock) and BCO (2ml/Kg b.w.orally) were solubilised in methanol. Rat chow was administered as
through orally. Bd and BCO suspension was also administrated through orally in two equal doses of 2
ml/Kg b.w.orally.

Isolation and Aqueous ethanolic Extraction ofBoerhaavia diffusa roots (Bd)
The fresh roots ofBoerhaavia diffusa linn. (Punarnava) were collected from the foothills of Dehradun(Uttarakhand) and its adjoining area and identified by Dr. R.L. Painuly at the Botany Department of
HNBGU and the specimen was preserved in the herbarium voucher no. GUH20434. The plant material
roots were washed, shad-dried avoiding sun drying due to the signature modification of the biochemical's,
therein under the influence of UV radiation (Sun-rays) pulverized, and finally sieved. 100 gm roots were
then subjected to soxhlet extraction using 70% hydro-alcoholic solvent (70% ethanol: 30% distilled water).
The final extract was filtered and the remaining alcohol was allowed to evaporate. Black Caraway Oil
parched market in Dehradun, which used as herbal medicine.
HPLC of extract ofB. diffusa (Bd)and Black Caraway Oil (BCO)
The technical details have been described by Simpson, C.F. (1978). Extraction of the constituents from Bd
and BCO were carried out using C18 PrepSep mini columns followed by quantification of the recovered
constituvents by HPLC on a reversed-phase muBondapack C18 analytical column, using an isocratic
mobile phase of water: methanol: 2-propanol (50: 45: 5% v/v) at a flow rate of 1ml/min, detection was
254nm.

Analytical Procedures
Collection of blood and packed erythrocytes
At the end of the experiment treatment, overnight fasted rats in each group were anaesthetized and blood
drawn from cardiac puncture. The blood from each rat in a given group was collected in heparinised tubes,
mixed gently by inversion 2-3 times and incubated at 40C for 2-3 h. Plasma was separated from blood by
centrifugation at 2,500 rpm for 30 min, aliquoted and stored at 40C or frozen at 200C for use in other
experiments. Packed erythrocytes hemolysate was prepared as described by Lakshmi and Rajagopal
(1998).
Collection of different organs
In addition to the blood, liver, kidney and pancrease from male rats were excised that kept into ice cold
saline. Portion of organs was immediately fixed in 10% neutral formalin for histological studies.
Preparation of liver, lung and kidney homogenate and post-mitochondrial supernatant
At the end of the experiment, liver, lung and kidney from each rat were promptly excised and chilled in ice
cold saline. After washing with saline, liver, lung and kidney were blotted and weighed. Each liver, lung
and kidney were cut into pieces, mixed and 10 g of wet tissue was homogenized with 90 ml of chilled 0.1
M sodium phosphate buffer, pH 7.4, containing 1.17 % KCl in a waring blender. The volume of each
homogenate was recorded and centrifuged at 1,000 rpm for 10 min at 40C. After centrifugation, a portion of
each homogenate from liver, lung and kidney thus obtained was aliquoted and stored at 200C. The
remaining portions of the liver, lung and kidney homogenates were centrifuged at12, 000 rpm for 20 min at
40C. The post-mitochondrial supernatant thus obtained was aliquoted and stored at 200C for future use.

Determination of free radical scavenging activity (antioxidant capacity) ofB. diffusa and BCO
The procedure of Mellors and Tappel (1966) as modified by Khanduja and Bhardwaj (2003) was used for
determining the free radical scavenging activity ofB. diffusa and Black Caraway Oil. The assay was
carried out in a medium containing 40 mM tris buffer, pH 7.4 and 125 M ethanolic solution of 2, 2-diphenyl-1-picryl hydrazyl (DPPH). The reaction was started by the addition of ethanolic solution ofB.
diffusa andBlack Caraway Oil (25-200 M) in a total volume of 2 ml. The samples were mixed thoroughly
and the absorbance was recorded in dark at 517 nm (27 20C) at 1 min time interval up to 10 min against
absolute ethanol.
Determination of plasma triglycerides
Triglycerides were determined by using enzymatic kit. The method uses a modified Trinder color reaction to
produce a fast, linear, end point reaction (Trinder, 1969). The intensity of the color produced after
incubation is directly proportional to the concentration of the triglycerides in the plasma samples when
measured at 500 nm in a Beckman DU 640 spectrophotometer. Triglycerides in plasma samples were
calculated by using a triolein standard.
Determination of plasma free fatty acid
Free fatty acid in plasma was estimated as described by Duncombe (1963). The procedure of Folch et al.
(1957) was used for extracting free fatty acid from plasma lipids.
Determination of all other parameter (LDL, VLDL, HDL, Sd-LDL, Lb-LDL, HMG-CoA, GST,Catalase, SOD, XO, GPx)
All parameter were estimated as described by slandered protocol.

Extraction ofB. diffusa (Bd)and Black Caraway Oil (BCO)The aqueous extract of B. diffusa was continued into dry solid by rotary vacuum
evaporator. The yield ofB. diffusa was 7.78%. The powder obtained was stored at 40C till
further use. Whereas Black Caraway oil extracts from black cumin or Nigella sativa L. seeds
was obtained from the local market (100% pure), which is marked as a medicine After both
1mg/1ml dilution in the methanol the extract was two equal doses of 2ml/Kg b.w.orally.
HPLC extracts ofB. diffusa (Bd)and Black Caraway Oil (BCO)The fraction was purified by HPLC have eleven peaks of B. diffusa (Bd) shows
Boeravinone A1, B1, C2, D, E, F, Hypoxanthine, Punarnavoside and Urosolic acid as the
major phytoconstituents and 4 main peaks found in Black Caraway Oil (BCO) in HPLC.
Pharmacological active constituents of the Black Caraway Oil (BCO) as found as
thymoquinone (TQ), dithymoquinone (DTQ), thymohydroquinone (THQ) and thymol (THY)
(Ghosheh, O.A. et. al., 1999).

Antioxidative Activities ofB. diffusa (Bd) and Black Caraway Oil (BCO)
Antiradical activity or hydrogen donating ability ofB. diffusa (Bd) and Black Caraway
Oil (BCO) was measured by using DPPH (2,2-diphenyl,1-picrylhydrazyl), which
reflects the antioxidative properties of these compounds. As shown in Fig. 2.2, the half
quenching concentrations (IC50) were as follows: B. diffusa (Bd), 44.42 M; BlackCaraway Oil (BCO), 38.11 M. These findings indicate that as compared to B. diffusa
(Bd) 89% was found more efficient then Black Caraway Oil (BCO) 76% respectively.B.
diffusa shows more free radical scavenging property then Black Caraway Oil.

DISCUSSION:
Hypercholesterolemia is firmly established as a primary risk factor for atherosclerotic
cardiovascular disease. In this present investigation we tried to examine the effect ofB.
diffusa (I-BdT) and Black Caraway Oil (I-BCOT) supplementation on overall
proatherogenic actions of DMBA-Induced carcinogenesis we found that in the white
albino rats DMBA-Induced inflated oxidative stress hypercholesterolemia and
carcinogenesis when compared with normal control rats.
The DMBA-Induced extensive proatherogenic changes, that occurred in rats, were
reflected on a variety of parameters, such as, hemoglobin, plasma and lipoprotein
lipids including cholesterol and apoB content of LDL and its subfractions and
antioxidant enzymes. Supplementation of infected rats with B. diffusa (I-BdT) and
Black Caraway Oil (I-BCOT) for treatments, significantly reduced the overall
oxidative burden and effectively the above altered parameters.

They quench free radicals in cell membranes and protect them against lipid peroxidation.
The higher antioxidant potency ofB. diffusa (Bd)as compared to Black Caraway Oil
(BCO).
The reduction in the free radical quenching efficiency ofB. diffusa (44.42 M) in
comparison to BCO (38.11 M). B. diffusa was found more efficient scavenger of
peroxyradical then Black Caraway Oil. (Fig 2.2)
Consistent with the results from infected rats (Table 1), rats DMBA-Induced also
exhibited significant decrease hemoglobin. Both B. diffusa (I-BdT) and Black Caraway
Oil (I-BCOT) were equally effective in increasing (18-22 %) the hemoglobin, the results
demonstrate that a DMBA-Induced a severe hyperlipidemia in I-C rats as compared to
normal control (NC).
8/2/2019 Ph.D.Presentation1
35/43
A much higher increase in plasma TG (111 % and atherogenic non-HDL-C (99 % vs. 45 %)
levels contributed to the increased degree of hyperlipidemia in I-C rats. On the other hand,in I-C rats, atherogenic HDL-C was decreased by only 14 %, in comparison to a decline of
49 % in I-BCOT, indicating a very mild dyslipidemia in I-C rats. Highly increased plasma
TG, TC, VLDL-C, LDL-C and atherogenic non-HDL-C concentrations in I-C rats were
significantly reduced to a level close to their counterparts in N-C rats, In complete contrast
to infected rats, B. diffusa treatment not only blocked the minimal decline of 14 % seen in
HDL-C level of I-C rats but increased it to a level, 21 % higher than normal control value.On the other hand, after treatment ofB. diffusa (I-BdT) and Black Caraway Oil (I-BCOT)
treatment, the cholesterol content of more antioxidative small, dense HDL3 was increased,
from a reduced value of only 4 % in I-C rats, to 42 % and 35 % higher than normal control
HDL3 value. These results demonstrate that bothB. diffusa (I-BdT) and Black Caraway Oil
(I-BCOT) exert a potent effect in normalizing the high levels of TG as well as atherogenic
non-HDL-C in DMBA-induced hyperlipidemia in rats.
8/2/2019 Ph.D.Presentation1
36/43
Consistent with these findings, LDL-C/HDL-C, HDL-C/TC, sd-LDL-C/HDL-C and lb-LDL-
C/HDL-C ratios were markedly altered (+ 128 %, - 49 %, + 308 % and + 51 %, respectively, vs.corresponding ratio values in N-C), in I-C rats (Table 5), while treatment withB. diffusa (I-BdT)
and Black Caraway Oil (I-BCOT) fully normalized these altered ratios to a level, 20 % to 25 %
better than their counterparts in N-C, indicating an excellent normalization of highly atherogenic
sd-LDL-C and LDL-C.
The significant increase in plasma, liver, lung and kidney lipid levels is consistent with a
significant increase (52 %) in liver HMG-CoA reductase activity of I-C rats (Table 7).
Treatment of I-C rats with dietary B. diffusa (I-BdT) and Black Caraway Oil (I-BCOT) was
associated with a significant decrease in hepatic HMG-CoA reductase activity, which was
restored to 55 % and 52 % of N-C value, thus, providing a mechanism for the reduction of
plasma and tissue lipids.
8/2/2019 Ph.D.Presentation1

Our results show a significant increase in plasma, liver, lung and kidney XO activity of DMBA-
Induced rats. B. diffusa (I-BdT) and Black Caraway Oil (I-BCOT) administration significantly
blocked this increase in XO activity and reduced it to a level close to corresponding normal
control values.
A similar decrease in hepatic CAT and SOD activitiesB. diffusa and Black Caraway Oil feeding
of I-C rats significantly reduced the FFA and lipid peroxidation products, and increased the CAT
and SOD activities in liver, lung and kidney, and reversed these parameters to near normal levels
(Table 11). These results indicate a potent free radical scavenging property of both B. diffusa (I-
BdT) and Black Caraway Oil (I-BCOT).
Our results show a decline in GSH (Table 12), Gred and GST activities and an increased GPxactivity in liver, lung and kidney of I-C rats (Table 13). In addition, since GSH also acts as
substrate and co-substrate in essential enzymatic reactions of Gpx and GST, reduction of GST
activity may also be due to decreased levels of GSH in tissues.

SUMMARY AND CONCLUSION
Several epidemiologic studies have established a strong and consistent link between DMBA-Inducing and
increased cardiac morbidity and mortality. Other studies show that in addition to substantial increase in oxidativestress, certain other compounds of DMBA-Induced. Our results showed that due to sustained free radical,
DMBA-Induced infected rats (155-182g) exhibited several proatherogenic actions, including a significant
increase in atherogenic non-HDL-C, with a concomitant decline in the cholesterol concentrations of
antiatherogenic HDL and its subfractions, HDL2 and HDL3. B. diffusa treatment of infected rats resulted in a
significant increase hemoglobin levels, which were reversed to 20 % of respective control values of age-matched
normal control (N-C). Our results show that in comparison to normal control (N-C), a modest and significant
increase in plasma total lipid and atherogenic non-HDL-C levels in infected rats (I-C), which were significantly
reversed to 42-98 % of normal control (N-C) value after treatment ofB. diffusa supplementation and BlackCaraway Oil similarly. However, cholesterol content of more antioxidative HDL3 was not affected during ofB.
diffusa treatment. This may be due to markedly increased production of oxidants and significantly diminished
antioxidant defense including a decline in total plasma antioxidants.

Consistent with the increase in plasma TG, FFA and TC levels of I-C rats, a significant increase in these lipids of
liver, lung and kidney were also observed. While, B. diffusa and Black Caraway Oil treatment of I-C rats was
associated with a significant decreases in TG, FFA and TC of each tissue. These results demonstrate that
sustained oxidative stress in I-C rats is also able to induce hyperlipidemia in the above tissues with a maximum
increase in hepatic TC, while both B. diffusa and Black Caraway Oil effectively blocked these increases and
restored the TG, FFA and TC levels of liver, lung and kidney close to corresponding normal control values.Treatment of I-C rats with dietaryB. diffusa and Black Caraway Oil was associated with a significant decrease in
plasma and tissue lipid levels as well as hepatic HMG-CoA reductase activity, which was restored to 55 % and 27
% of N-C value, which may provide a mechanism for the reduction of plasma and tissue lipids.

Based on strong hypolipidemic and antioxidant properties ofB. diffusa (I-BdT) and Black Caraway Oil (I-
BCOT), we have investigated the anti-tumour activity of I-BdT and I-BCOT in experimental carcinogenesis of
liver, kidney and pancreases. We have utilized the carcinogen, DMBA, which is known to induce hepatic
carcinogenesis and hypercholesterolemia. As expected, administration of DMBA causes a significant increase in
plasma triglycerides, total cholesterol, LDL-C and apo-B levels. Feeding ofB. diffusa (I-BdT) and Black
Caraway Oil (I-BCOT) to rats, during pre- and post-initiation stages, was associated with a significant decline in
the above lipid parameters.
Treatment with DMBA resulted in the formation of neoplastic nodules, which evident from the appearance of
multiple tumours on greyish white patches on the liver of the carcinogen treated rats. Morphological and
histological examination of liver, kidney and pancreases from rats treated with DMBA, revealed damage to the
cells, particularly the nuclei. Consistent with morphological and histological examinations, elevated the
carcinogen treated rats are indicative of the severity of liver, lung and kidney carcinogenesis.

It is well known that DMBA-Inducing is associated with a substantial increase in oxidative stress, oxidant
stress may be increased owing to a higher production of ROS, which are controlled by antioxidant enzymes,
SOD, catalase, Gpx, Gred and GSH. An impaired radical scavenger function has been linked to
decreased/increased activity of enzymatic and nonenzymatic antioxidants. Our results show a significant
decrease in the activities of antiperoxidative enzymes, CAT, SOD, Gred, GST as well as GSH, in liver, lung
and kidney of DMBA-Induced rats, except Gpx activity which was significantly increased. Treatment of
DMBA-Induced hyperlipidemic rats withB. diffusa
and Black Caraway Oil, significantly reversed/restoredthe altered tissue activities of SOD, catalase, Gpx, Gred and GST including total, free and protein bound-SH
contents of glutathione, to near normal control values, indicating an almost total alleviation of oxidative
damage by these antioxidants. Both B. diffusa and Black Caraway Oil mediated a near normalization of
peroxide levels and scavenging enzyme activities as well as GSH in liver, lung and kidney of infected rats,
indicating a strong antilipid/lipoprotein peroxidative effect of these hypolipidemic and anticarcinogenic
agents.

The combined results provide evidence that analysis of marker enzymes, GST, lipid peroxide and
examination of gross morphology and histology suggested that B. diffusa (I-BdT) and Black Caraway Oil (I-
BCOT) feeding did offer a significant protection and did reduce the severity and extent of neoplastic
transformation during both initiation and/or promotion in the liver and kidney of experimental carcinogenic rats.B. diffusa (I-BdT) and Black Caraway Oil (I-BCOT) treatment, in addition to its anti-cancer and antioxidant
impacts, also exerted a strong hypocholesterolemic action, indicating a linkage between atherosclerosis and
cancer. The dual chemotherapeutic properties ofB. diffusa (I-BdT) and Black Caraway Oil (I-BCOT) in
atherosclerosis and cancer are apparently mediated by reducing HMG-CoA reductase, thus limiting the
availability of mevalonate-derived products required for cholesterol production and tumour growth. Daily use of
B. diffusa (I-BdT) and Black Caraway Oil (I-BCOT) by normal population will prevent the occurrence of
hypercholesterolemia and cardiovascular diseases as well as initiation and promotion of certain forms of cancer.
In conclusion, based onB. diffusa mediated multiple therapeutic benefits, described in the present study,
daily intake of Black Caraway Oil as a dietary supplement by hypolipidemic /antiatherogenic
/antihypercholesterolemic, antioxidant actions and anticarcinogenic may be useful in the prevention and
treatment of DMBA-Induced hyperlipidemia/ and atherosclerosis. In addition, daily use of dietary B. diffusa
and Black Caraway Oil will be efficacious, cost effective, no side effects and a good source of
antihypercholesterolemic, antioxidant actions and anticarcinogenic.
