| alpha-solanine | A glycoalkaloid poison found in species of the nightshade family (Solanaceae), such as the potato (Solanum tuberosum). It is a trisccharide derivative of solanidine [(22beta)-solanid-5-en-3beta-ol]. | solanine |
| 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 |
| beta-solamarine | | Beta-Solamarine |
| chinenoside ii | | Chinenoside II |
| digoxigenin-mono(digitoxoside) | A steroid saponin that consists of digoxigenin having a digitoxosyl residue attached at position 3. | digoxigenin monodigitoxoside |
| digoxin | A cardenolide glycoside that is digitoxin beta-hydroxylated at C-12. A cardiac glycoside extracted from the foxglove plant, Digitalis lanata, it is used to control ventricular rate in atrial fibrillation and in the management of congestive heart failure with atrial fibrillation, but the margin between toxic and therapeutic doses is small. | digoxin |
| esculeoside a | A steroid saponin that is spirosolane-3,23,27-triol in which the hydroxy group at position 23 is acetylated and the hydroxy groups at positions 3 and 27 are glycosylated by lycotetraosyl and a beta-D-glucopyranosyl moieties respectively. Isolated from the fruits of Lycopersicon esculentum, it exhibits cytotoxic activity. | esculeoside A |
| estriol 17-glucuronide | | 16alpha,17beta-Estriol 17-(beta-D-glucuronide) |
| estriol 3-sulfate 16-glucuronide | | Estriol 3-sulfate 16-glucuronide |
| furostanol i | 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 26-(beta-D-glucopyranosyloxy)-3beta,22-dihydroxyfurost-5-ene via a glycosidic linkage. Found in several plant species including yams, asparagus and funugreek. | protodioscin |
| lyoniside | A steroid saponin that is sitosterol attached to a beta-D-glucopyranosyl residue at position 3 via a glycosidic linkage. It has bee isolated from Panax japonicus var. major and Breynia fruticosa. | daucosterol |
| oleandrin | A steroid saponin that consists of oleandrigenin having a 2,6-dideoxy-3-O-methyl-alpha-L-arabino-hexopyranosyl residue attached to the oxygen function at position 3. | oleandrin |
| ophiopogonin b | | Ophiopogonin B |
| ophiopogonin d | | Ophiopogonin D |
| prosapogenin a | | Prosapogenin A |
| stigmasterol 3-o-beta-d-glucopyranoside | A steroid saponin that is (3beta,22E)-stigmasta-5,22-dien-3-ol attached to a beta-D-glucopyranosyl residue at position 3 via a glycosidic linkage. It is isolated from Symplocos lancifolia. | stigmasterol 3-O-beta-D-glucoside |
| timosaponin b-ii | | Melongoside N |
| tuberoside | | Tuberoside |
