| FooDB Name | Diosgenin |
|---|
| Description | Diosgenin is a member of the class of compounds known as triterpenoids. Triterpenoids are terpene molecules containing six isoprene units. Diosgenin is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). Diosgenin can be found in a number of food items such as carrot, wild carrot, yam, and bitter gourd, which makes diosgenin a potential biomarker for the consumption of these food products. Diosgenin, a phytosteroid sapogenin, is the product of hydrolysis by acids, strong bases, or enzymes of saponins, extracted from the tubers of Dioscorea wild yam, such as the Kokoro. The sugar-free (aglycone) product of such hydrolysis, diosgenin is used for the commercial synthesis of cortisone, pregnenolone, progesterone, and other steroid products . |
