Member | Definition | Role |
bufalin | A 14beta-hydroxy steroid that is bufan-20,22-dienolide having hydroxy substituents at the 5beta- and 14beta-positions. It has been isolated from the skin of the toad Bufo bufo. | bufalin |
convallatoxin | A cardenolide glycoside that consists of strophanthidin having a 6-deoxy-alpha-L-mannopyranosyl (L-rhamnosyl) group attached at position 3. | convallatoxin |
deslanoside | A cardenolide glycoside that is lanatoside C with the acetoxy group replaced by a hydroxy group. | deslanoside |
digitoxigenin | A 5beta-cardenolide that is 5beta-cardanolide with hydroxy substituents at the 3beta- and 14beta-positions and double bond unsaturation at C(20)-C(22). | digitoxigenin |
digoxigenin | A hydroxy steroid that consists of 5beta-cardanolide having a double bond at the 20(22)-position as well as hydroxy groups at the 3beta-, 12beta- and 14beta-positions. It has been isolated from the plant species of the genus Digitalis. | digoxigenin |
