Triterpenoid Glycosides from the Roots of Patrinia scabiosaefolia.
Four saponins were isolated from the roots of PATRINIA SCABIOSAEFOLIA (Valerianaceae) and identified as 3- O-alpha- L-arabinopyranosylhederagenin 28- O-beta- D-glucopyranosyl(1-->6)-beta- D-glucopyranoside ( 2) and its 2'-acetate ( 1) and 3- O-beta- D-glucopyranosyl(1-->3)-alpha- L-rhamnopyranosyl(1-->2)-alpha- L-arabinopyranosyloleanolic acid ( 3) and its 28- O-beta D-glucopyranosyl(1-->6)-beta- D-glucopyranoside ( 4).
