A new triterpenoid saponin was isolated from the tubers of Thladiantha hookeri C.B.Clarke var. pentadactyla in a high yield (9.7percent).On the basis of chemical and spectral evidence, the structure was determined as β-xylopyranosyl-(1->3)-β-xylopyranosyl-(1->4)-α-rhamnopyranosyl-(1->2)-β-xylopyranosyl ester of 3-O-β-galactopyranosyl-(1->2)-β-glucuronopyranosyl-gypsogenin.The solubilizing effect of this saponin is also described.Key Word Index- Thladiantha hookeri var. pentadactyla; Cucurbitaceae; Wu-ye-chi-pa; Chinese folk medicine; gypsogenin.
