This study examined the inhibitory effect of Stigmast-5-en-3-O-glucopyranosidetriacetate-51-ol (SGTA), an isolate from petroleum ether extract of Cuscuta reflexa and performed comparative study of petroleum ether extract (PTE), ethanolic extract (ETE) and SGTA on hair growth activity in androgenic alopecia rat model. Alopecia induced in albino rats by testosterone administration subcutaneously for 21 days. Finasteride solution was applied topically served as standard. In vitro experiment to study the effect of extracts and isolate on activity of 5α-reductase enzyme and comparing with finasteride. In vivo experiment showed that rat follicular density and anagen/telogen (A/T) ratio were increased in the PTE, ETE and SGTA treated group when compared to a control group. Skin histological results shown that the PTE, ETE and SGTA treated group had an increase in number and shape of the hair follicles and increase in the follicle anagen/telogen ratio when compared to the finasteride and control group. The result indicated that the ethanolic, petroleum ether extract and isolate of petroleum ether extract of C. reflexa found useful in the treatment of androgen-induced alopecia in the experimental animal. In summary, SGTA and extract control the apoptosis of hair cells and retarded the testosterone induce alopecia and therefore be a natural product with much impending for use as a treatment for androgenic alopecia
