Triterpenoid Glycosides from the Roots ofPatrinia scabiosaefolia

Abstract
Four saponins were isolated from the roots of Patrinia scabiosaefolia (Valerianaceae) and identified as 3-O-α-L-arabinopyranosylhederagenin 28-O-β-D-glucopyranosyl(1→6)-β-D-glucopyranoside (2) and its 2′-acetate (1) and 3-O-β-D-glucopyranosyl(1→3)-α-L-rhamnopyranosyl(1→2)-α-L-arabinopyranosyloleanolic acid (3) and its 28-OD-glucopyranosyl(1→6)-β-D-glucopyranoside (4).
