ANTI-OXIDANT ANDANTI-CANCER POTENTIAL OF SYMPLOCOS RACEMOSA BARK AGAINST HEP3B CELL LINE

Objective: The aim of this study is to evaluate anti-oxidant and anticancer activity of methanol extract and ethyl acetate soluble fraction of methanol extract of Symplocos racemosa bark against the hepatocellular carcinoma. Materials and methods: DPPH and H₂O₂ free radical scavenging assay were tested for determining the anti-oxidant activity. Rat normal liver cells (BRL-3A) and human hepatocellular carcinoma (Hep3B) cells were tested in-vitro for cytotoxicity using (3-4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay. Result: Ethyl acetate soluble fraction of methanol extract of Symplocos racemosa bark exhibited significant DPPH and H2O2free radical scavenging activity withIC50 value (µg/ml) of 10.58 and 11.89 as compared to standard drug ascorbic acid. Ethyl acetate soluble fraction of methanol extract of Symplocos racemosa bark exhibited significant cytotoxicity against human hepatocellular carcinoma (Hep3B) cells in-vitrowithIC50 value (µg/ml) of 32.55 as compared to standard doxorubicin (55.43µg/ml), and not affected the normal liver (BRL-3A) cells. Conclusion: Symplocos racemosa bark showed the potent anti-oxidant and anticancer activity. It may be due to presence of phytochemicals which are responsible for the anticancer activity.
