---|---|---|
cucurbitacin b | A cucurbitacin in which a lanostane skeleton is multi-substituted with hydroxy, methyl and oxo substituents, with unsaturation at positions 5 and 23; a hydroxy function at C-25 is acetylated. | cucurbitacin B |
cucurbitacin c | Cucurbitacin C | |
cucurbitacin d | A cucurbitacin in which a lanostane skeleton is multi-substituted with hydroxy, methyl and oxo substituents, with unsaturation at positions 5 and 23. | cucurbitacin D |
cucurbitacin i | A cucurbitacin that is 9,10,14-trimethyl-4,9-cyclo-9,10-secocholesta-2,5,23-triene substituted by hydroxy groups at positions 2, 16, 20 and 25 and oxo groups at positions 1, 11 and 22. | cucurbitacin I |
cucurbitacin I 2-O-beta-D-glucopyranoside | A triterpenoid saponin that is cucurbitacin I attached to a beta-D-glucopyranosyl residue at position 2 via a glycosidic linkage. It has been isolated from Machilus yaoshansis. | cucurbitacin I 2-O-beta-D-glucopyranoside |
