Phytochemical Evaluation and Anticancer Activity on Root Extracts of Jatropha Gossypiifolia Linn
2016
INTRODUCTION: Cancer, in medicine, common term for neoplasms, or tumors, that are malignant. Like benign
tumors, malignant tumors do not respond to body mechanisms that limit cell growth. Unlike
benign tumors, malignant tumors consist of differentiated, or unspecialized, cells that show
an atypical cell structure and do not function like the normal cells from the organ from which
they derive. Cancer is the major disorder, which increases morbidity and mortality in both
male and females. Certain genes control the life cycle – the growth, function, division, and death -- of a cell.
When these genes are damaged, the balance between normal cell growth and death is lost.
Cancer occurs due to DNA damage and out-of-control cell growth. The following is a partial
list of factors known to damage DNA and increase the risk of cancer:AIM:To evaluate phytochemical and in vitro anti-cancer activity on roots of Jatropha
gossypiifolia Linn OBJECTIVE: 1. To perform Soxhlet extraction on roots of Jatropha gossypiifolia
2. To evaluate preliminary phytochemical screening and in vitro anti-cancer
activity of the extracts on Breast Cancer line (MCF-7)
3. To subject the active extract for fractionation in column chromatography in
solvents from non-polar to polar by gradient elution.(n-hexaneto ethanol)
4. To evaluate the anticancer activity in fractions on Breast Cancer line (MCF-7).
5.To perform Preparative HPLC for the bio active fraction and isolate the pure
compound by observing the peak area , height and retention time.
6.To characterize the compound byFT-IR,1HNMR, GCMS and interpret it to
determine the structure.
7.To perform the docking studies for the isolated compound on breast cancer
target protein human tankyrase 2.
8.To investigate Gene expression of isolated compound by RT PCR method.SUMMARY:The chloroform and ethanol extracts was prepared from the dried powdered roots of Jatropha
gossypiifoliaby hot continuous percolation method using soxhletapparatus.The extracts was
subjected to preliminary phytochemical screening and was found that, secondary metabolites
such as steroids, alkaloids, glycosides, flavonoids and phenolic compounds. It was found that
ethanol extract shows the presence of flavonoids and phenolic compounds and it is absence in
chloroform extract.
Bio guided Isolation
In vitro anticancer activity
The chloroform and ethanol extract was subjected to in vitro anticancer activity on MCF – 7
cell line. The ethanol extract shows better anti-cancer activity than chloroform extract with
the percentage growth of 28.46 on MCF –7cells. Since the present scheme of work is
bioguided isolation, the active extract (ethanol extract) was selected for isolation by column
chromatography.
Isolation by column chromatography
Ethanol extract was subjected to column chromatography isolation by gradient elution
technique. The yellowish green fraction was started eluting fromfractions(chloroform 100%),
chloroform: ethylacetate (160:40), (150:50), (100:100) and ethyl acetate 100%. The brown
colour fraction was started eluting from fractions (ethylacetate: ethanol) and ethanol
100%.TLC was determined for the above fractions. The fractions with the same Rfvalue were
mixed to contain totally of 4 fractions. Fraction 1 (chloroform fraction), fraction 2
(chloroform: ethylacetate), fraction 3 (ethyl acetate: ethanol)and fraction 4 (ethanol 100%).
In Vitro anticancer activity of fractions
All the 4 fractions were subjected to anticancer activity on MCF – 7 cell lines. The fraction 4
(Ethanol 100%) shows the good anticancer activity compared to other fractions against MCF
-7 cell line. The percentage growth of MCF-7 cells in fraction (1 -4) was found to be 24.527,
49.132, 36.909, 14.650 respectively. The EC50 value was found to be for fractions (1- 4) was
found to be 0.00082, 0.1728, 0.00028, 0.00087mg/ml respectively.CONCLUSION:The conclusion of the study present study is the ethanol extract and ethanol fraction of
Jatropha gossypifolia (root) from column chromatography is proved to have antineoplastic
activity. The flavone which is isolated from ethanol fraction is proved to be an effective
antineoplastic agent .against MCF-7 cell line.
