【Abstract】 Three new saponins,3 O {〔β D glucopyranosyl (16) β D glucopyranosyl(12)〕 〔β D glucopyranosyl(13)〕 α L arabinopyranosyl}oleanolic acid 28 O β D glucopyranosyl (16) β D glucopyranoside(congmunoside Ⅻ,1),3 O {〔β D glucopyranosyl (16) β D glucopyranosyl(12)〕 〔β D glucopyranosyl(13) β D glucopyranosyl(13)〕 α L arabinopyranosyl}oleanolic acid 28 O β D glucopyranosyl (16) β D glucopyranoside(congmunoside ,2),Oleanolic acid 3 O {〔β D xylopyranosyl (12)〕 〔β D galactopyranosyl (13)〕 (β D glucuronopyranoside 6′ O butyl ester)} 28 O β D glucopyranoside(congmunoside ,3),were isolated from the root bark of Aralia elata (Miq.)Seem.Their structures were determined on the basis of chemical and spectroscopy methods.更多还原
