Leaves of P.cerasoides were collected from Shillong, Meghalaya.The methanolic extract of the plant was fractionated by column chromatography. For in-vivo studies, wistar male rats were divided into groups, first group received propylene glycol (0.2 ml/rat i.p.), second group received testosterone (0.2 mg/rat s.c.), third group received testosterone with plant extract (10 mg/kg body weight, i.p.) and the last group received testosterone with standard drug (Finasteride). One group of uncastrated rat received propylene glycol (0.2ml/rat i.p.). After 30 days all the animals were sacrificed under anesthesia and the total prostate weight was measured for all the animals.
