Diosgenin (Fig. 4) is a steroid sapogenin produced by Dioscorea species. This natural product is used as a precursor for the commercial synthesis of medicinal steroids such as prednisolone, dexamethasone, norethisterone, and metenolone, among others. Microtuber-derived cell suspensions of Dioscorea doryophora were able to accumulate diosgenin at concentrations as high as 3.5% g dw. Embryogenic callus of Tribulus terrestris were also able to accumulate diosgenin (170.7 1.0 pg/g dw). ...
