''Dioscorea composita'' or barbasco is a species of yam in the genus ''Dioscorea'', native to Mexico. It is notable for its role in the production of diosgenin, which is a precursor for the synthesis of hormones such as progesterone.〔http://www.ars-grin.gov/cgi-bin/npgs/html/taxon.pl?14226〕 Russell Marker developed the extraction and manufacture of hormones from ''D. mexicana'' at Syntex, starting the trade of ''D. composita'' in Mexico. Marker also discovered that the ''composita'' variety had a much higher content of diosgenin than the ''mexicana'' variety, and therefore it came to replace the latter in the production of synthetic hormones.〔http://www.americanheritage.com/articles/magazine/ah/1978/5/1978_5_80.shtml〕 == Chemical constituents == Steroidal sapogenin, diosgenin.〔Indian herbal pharmacopia Vol.II.〕
