Two New Triterpene Glycosides in the Roots of Uraria crinita.

Abstract

Two new triterpene glycosides, 24-deoxyoxytrogenin 3-O-α-L-rhamnopyranosyl (1→2)[β-D-glucopyranosyl]-β-D-galactopyranosyl (1→2)-β-D-glucuronopyranoside and sophoradiol 3-O-α-L-rhamnopyranosyl (1→2)-β-D-glucuronopyranosyl (1→2)-β-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.
