Abstract:Trapa bispinosa Roxb. pericarp extract (TBE) has a polyphenol-rich composition and exhibits potent antioxidant and anti-glycation activities in vitro. In the present study, we investigated the inhibitory effects of TBE on 5α-reductase in vitro using LNCaP cells and in vivo using a mouse model of castrated benign prostatic hyperplasia. TBE showed concentration-dependent inhibitory effects in the 5α-reductase (5αR) activity assay. In a reporter assay using AR-Luc/LNCaP cells, TBE inhibited the activity induced b… Show more
