From the fresh roots of Trichosanthes cucumeroides MAIXM., three new triterpenoid glycosides with a bitter taste were obtained together with methyl palmitate, palmitic acid, α-spinasterol, stigmast-7-en-3β-ol, α-spinasterol 3-O-β-D-glucopyranoside, stigmast-7-en-3β-ol 3-O-β-D-glucopyranoside and vanillic acid. On the basis of the results of spectral and chemical investigations, these glycosides were characterized as 25-O-β-D-glucopyranosyl-11-oxocucurbit-5-ene-3β, 24 (R), 25-triol 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside, 25-O-β-D-(6-O-acetyl)-glucopyranosyl-11-oxocucurbit-5-ene-3β, 24 (R), 25-triol 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside and 11-oxocucurbit-5-ene-3β, 24 (R), 25-triol 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranosyl-(1→2)-β-D-glucopyranoside.
