    Objective: The present study was designed to examine the cytotoxic effects of methanolic extract of aerial parts of Corchorus depressus and hexane, chloroform, ethyl acetate, and aqueous fractions of the same extract in the human hepatocellular carcinoma (HCC) (HepG2) and invasive hepatocellular carcinoma cell lines (HLE).Methods: Anti-proliferative effects were evaluated using 3-(4,5-dimethythiazol2-yl)-2,5-diphenyl tetrazolium bromide (MTT) and neutral red uptake (NRU) assay. Human HCC (HepG2) and invasive hepatocellular carcinoma cell lines (HLE) were treated with different concentrations of methanolic extract (10, 25, 50, 100, 200, 300, 400, and 500 μg/mL) of aerial parts of C. depressus as well as hexane, chloroform, ethyl acetate, and aqueous fractions (200 μg/mL) for 24 and 48 h. The cell viability and the half maximal inhibitory concentration (IC50) were determined.Results: The maximum cytotoxic effect was noticed with a maximum dose of methanolic extract (500 μg/mL) and alkaloidal fraction (200 μg) in this study with an IC50 value of about 200 μg.Conclusion: The set of studies showed that methanolic extract of aerial parts of C. depressus and alkaloidal, chloroform and ethyl acetate fractions fractions was capable of inhibiting cell growth and cell proliferation by inducing cytotoxicity of HepG2 and HLE cells

    Objective: Alysicarpus monilifer (Family Papilionaceae) has been used in the Indigenous system of medicine in tumor removal. The present study was designed to isolate and identify the constituent responsible for cytotoxic (anti-tumor) effects of the plant Alysicarpus monilifer. Methods: The plant was powdered and extracted to give a methanolic extract. Initially, Hexane, chloroform, ethyl acetate and methanolic fractions of the methanolic extract of the plant were subjected to cytotoxic screening using cell line based assay (MTT assay and NRU assay). The chloroform fraction showed significant cytotoxicity, so it was further subjected to column chromatography, to separate the cytotoxic phytoconstituent. The cell lines selected were breast cancer cells (MCF-7 and MDA-MB-468) and Liver cancer cells (HepG2 and HLE cell). Results were calculated as percentage growth inhibition with respect to untreated (control) cells versus treated cells. Result: A triterpene, Betulinic acid, was isolated from the aerial parts of Alysicarpus monilifer. The cytotoxic activity of the identified compound against MCF-7, MDA-MB-231, HLE and HepG2 cells was also found to be highly significant with 90% growth inhibition. Conclusion: The triterpene was identified to be betulinic acid, to which the cytotoxic activity can be attributed. It is a first report of isolation of betulinic acid from the Alysicarpus species
