Phytochemical screening and evaluation of cytotoxic and hypoglycemic properties of Mangifera indica peels

Objective: To investigate the presence of different phytoconstituents in Mangifera indica(M. indica) peel and evaluate its cytotoxicity to Artemia salina and hypoglycemic potential in Swiss albino mice.Methods: The methanolic extract of M. indica peel was used to determine the presence of phytoconstituents. Brine shrimp lethality bioassay method was followed to determine the cytotoxic potential of plant extract. In the case of hypoglycemic activity, oral administration of extract at 200 and 400 mg/kg and standard glibenclamide at 10 mg/kg was done, followed by determining the percentage of reduction of plasma glucose from the initial level.Results: The methanolic extract of M. indica peel showed the presence of flavonoid,saponin, steroid, tannins, terpenoids, glycosides and alkaloids. In brine shrimp lethality bioassay, the LC_(50) of the extract and standard vincristine sulfate was found to be 2.04 and0.41 mg/mL, respectively. After 90 and 150 min, the methanolic extract at 200 and 400 mg/kg showed prominent plasma glucose reduction of 13.95%, 22.48% and 14.16%,26.18% respectively compared to standard glibenclamide showing 14.90% and 20.67% plasma glucose reduction.Conclusions: This current research affirms prominent cytotoxic and moderate hypoglycemic potential of M. indica peel. Further bioactivity guided isolation of phytoconstituents and investigation on higher animals can lead to development of new drug molecules.
