| avenacoside b | A steroid saponin obtained from grain and leaves of oats (Avena sativa) that is nuatigenin in which the hydroxy group at position 26 is converted to its beta-D-glucoside and in which the hydroxy group at position 3 is converted into its methyl alpha-L-rhamnopyranosyl-(1->2)-[beta-D-glucopyranosyl-(1->3)-beta-D-glucopyranosyl-(1->4)]-beta-D-glucopyranoside derivative. | avenacoside B |
| capilliposide b | A triterpenoid saponin that consists of anagalligenin A substituted by a caproyl group at position 22 and a beta-D-xylopyranosyl-(1->2)-beta-D-glucopyranosyl-(1->4)-[beta-D-glucopyranosyl-(1->2)]-alpha-L-arabinopyranosyl moiety at position 3 via a glycosidic linkage. It is isolated from the whole plants of Lysimachia capillipes and has been shown to exhibit potent cytotoxicity against human A-2780 cells. | capilliposide B |
| dioscin | 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 |
| diosgenin | A sapogenin that is spirostan which is substituted by a hydroxy group at the 3beta position, contains a double bond at the 5-6 position, and has R- configuration at position 25. A natural product found in Dioscorea (wild yam) species, it is used as the starting point for the commercial synthesis of a number of steroids, including cortisone, pregnenolone and progesterone. | diosgenin |
| diosgenin glucoside | A sterol 3-beta-D-glucoside having diosgenin as the sterol component. | diosgenin 3-O-beta-D-glucoside |
| limonin | | limonin |
