Two New Triterpene Glycosides in the Roots of Uraria crinita.

Two new triterpene glycosides, 24-deoxyoxytrogenin 3-O-alpha-L-rhamnopyranosyl (1 -> 2)[beta-D-glucopyranosyll]-beta-D-galactopyranosyl (1 -> 2)-beta-D-glucuronopyranoside and sophoradiol 3-O-alpha-L-rhamnopyranosyl (1 -> 2)-beta-D-glucuronopyranosyl (1 -> 2)-beta-D-glucuronopyranoside with four known glycosides were isolated from a Chinese natural medicine, the roots of Uraria crinita (L.) DESV. Their structures were determined by chemical and spectral methods.
