ABSTRACT
Type I 5α-reductase has been implicated in skin disorders such as acne, hirsutism and male pattern baldness and its inhibition offers a potential treatment for these disorders. The aim of this study was to investigate the inhibition of type I 5α-reductase activity by extracts from Indian medicinal plants. Plant extracts were screened and selected based on their ability to inhibit Propionibacterium acnes and Staphylococcus epidermidis. Since type I 5α-reductase metabolises testosterone to Δ4-androstene-3, 17-dione, the activity of enzyme was determined using RIA for testosterone and Δ4-androstene-3, 17-dione. It was found that methanolic extract of Embelia ribes was a potent inhibitor of type I 5α-reductase (IC50:100μg/mL). Extracts of Vitex negundo, Terminalia chebula, and Terminalia bellerica which also inhibited type I 5α-reductase (IC50: 200-390 μg /mL). Therefore herbal formulation of these plant extracts may be used in the treatment of skin disorders involving type I 5α-reductase.
