(16alpha,20R,24S)-2,16,20,25-tetrahydroxy-24-methoxycucurbita-1,5-diene-3,11,22-trione 2-O-beta-D-glucopyranoside

(16alpha,20R,24S)-2,16,20,25-tetrahydroxy-24-methoxycucurbita-1,5-diene-3,11,22-trione 2-O-beta-D-glucopyranoside is a triterpenoid saponin that is cucurbita-1,5-diene substituted by hydroxy groups at positions 16, 20 and 25, a methoxy group at position 24, oxo groups at positions 3, 11 and 22 and a beta-D-glucopyranosyloxy residue at position 2. It has been isolated from the roots of Machilus yaoshansis. It has a role as a plant metabolite. It is a tertiary alpha-hydroxy ketone, a cucurbitacin, a beta-D-glucoside, a triterpenoid saponin and a monosaccharide derivative.
