The structures of the two saponins were elucidated as 3 α hydroxyolean 9(11), 12 diene 28 oic acid 28 O α L rhamnopyranosyl (1→4) β D glucopyranosyl (1→6) β D glucopyranoside(1) and 3 α hydroxyolean 11,13(18) diene 28 oic acid 28 O α L rhamnopyranosyl (1→4) β D glucopyranosyl(1→6) β D glucopyranoside(2), respectively.展开更多
