| acarbose | A tetrasaccharide derivative consisting of a dideoxy-4-{[4,5,6-trihydroxy-3-(hydroxymethyl)cyclohex-2-en-1-yl C7 cyclitol moiety [called valienol (or valienamine)] linked via nitrogen to isomaltotriose. | acarbose |
| 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 |
| dehydrotomatine | A steroid alkaloid that consists of tomatine which has undergone formal dehydrogenation across positions 5 and 6. Found in tomatoes. | 5,6-dehydrotomatine |
| deslanoside | A cardenolide glycoside that is lanatoside C with the acetoxy group replaced by a hydroxy group. | deslanoside |
| ristocetin | A heterodetic cyclic peptide that is produced by species of Amycolatopsis and Nocardia. | ristocetin |
| tomatine | A steroid alkaloid that is tomatidine in which the hydroxy group at position 3 is linked to lycotetraose, a tetrasaccharide composed of two units of D-glucose, one unit of D-xylose, and one unit of D-galactose. | tomatine |
