Dioscin is a spirostanyl glycoside that consists of the trisaccharide alpha-L-Rha-(1->4)-[alpha-L-Rha-(1->2)]-beta-D-Glc attached to position 3 of diosgenin via a glycosidic linkage. It has a role as a metabolite, an antifungal agent, an antiviral agent, an antineoplastic agent, an anti-inflammatory agent, a hepatoprotective agent, an apoptosis inducer and an EC 1.14.18.1 (tyrosinase) inhibitor. It is a spirostanyl glycoside, a spiroketal, a hexacyclic triterpenoid and a trisaccharide derivative. It is functionally related to a diosgenin. It derives from a hydride of a spirostan. Dioscin is a natural product found in Ophiopogon intermedius, Dracaena draco, and other organisms with data available. See also: Dioscorea polystachya tuber (part of). A spirostanyl glycoside that consists of the trisaccharide alpha-L-Rha-(1->4)-[alpha-L-Rha-(1->2)]-beta-D-Glc attached to position 3 of diosgenin via a glycosidic linkage. Dioscin is a member of the class of compounds known as steroidal saponins. Steroidal saponins are saponins in which the aglycone moiety is a steroid. The steroidal aglycone is usually a spirostane, furostane, spirosolane, solanidane, or curcubitacin derivative. Dioscin is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). Dioscin can be found in fenugreek and yam, which makes dioscin a potential biomarker for the consumption of these food products.
