Phytochemical studies of seeds of medicinal plants. I. Two sulfated triterpenoid glycosides, sulfapatrinosides I and II, from seeds of Patrinia scabiosaefolia FISCHER.

Abstract

Two new sulfated glycosides were isolated as major constituents from seeds of Patrinia scabiosaefolia FISCHER (Valerianaceae). These compounds, termed sulfapatrinosides I (1) and II (2), have been established to be 23-sulfates (in the forms of the sodium salts) of 3β-hydroxyurs-12-en-28-oic acid 28-O-[β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl] ester and 3β-hydroxyolean-12-en-28-oic acid 28-O-[β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl] ester, respectively, based on chemical and spectral evidence.
