10.22376/ijpbs.2019.10.1.p1-12 Volume 9 Issue 1 2018 (January-March) The aim of the study was to find out the anthocyanin and anticancer efficacy of lessThan i greaterThan Pithecellobium dulce lessThan /i greaterThan (Roxb.) Benth fruits extract against MCF -7 (Michigdan Cancer Foundation-7).Different concentration (10, 20, 30, 40, and 50 μg/ml) of methanol extract of lessThan i greaterThan P.dulce lessThan /i greaterThan fruits were used to assess the lessThan i greaterThan in vitro lessThan /i greaterThan cytotoxic effect using 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. lessThan i greaterThan Pithecellobium dulce lessThan /i greaterThan fruits contain 6.23 % of anthocyanin. The various concentrations of crude methanol extract (10, 20, 30, 40, and 50 μg/ml concentration) of lessThan i greaterThan Pithecellobium dulce lessThan /i greaterThan fruits were performed for cytotoxic activity. The effect of inhibition of cell growth showed significantly cytotoxic against MCF-7 cell line with an inhibit cell growth by 50% (IC50) of 24μg/ml.The present study concludes that the methanol extract of lessThan i greaterThan Pithecellobium dulce lessThan /i greaterThan fruits possess potent cytotoxic activity.
