Evaluation of antioxidant, in vitro cytotoxicity of micropropagated and naturally grown plants of Leptadenia reticulata (Retz.) Wight & Arn.-an endangered medicinal plant.

Objective: To evaluate the antioxidant and anti proliferative potential of different solvent extract of micropropagated and naturally grown plants of Leptadenia reticulata against various cancer cell lines.

Methods: In this study different extract were tested for cytotoxicity against human breast adenocarcinoma cell line MCF-7, human colon adenocarcinoma grade II cell line HT-29 and non cancer skeletal muscle cell line L6 through 3-(4, 5-dimethyl thiazol-2-yl)-5-diphenyl tetrazolium bromide assay. The total antioxidant potential was estimated by three different antioxidant model diphenylpicrylhydrazyl free radical scavenging activity, H2O2 scavenging activity and FeCl3 reducing activity.
