They were characterized as adinaic acid 3 beta-O-[alpha-L-rhamnopyranosyl(1-->2)-beta-D-glucopyranosyl(1-->2)-beta-D-glucurono-pyranoside-6-O-methyl ester]-28-O-beta-D-glucopyranoside, adinaic acid 3 beta-O-[alpha-L-rhamnopyranosyl(1-->2)-beta-D-glucopyranosyl(1-->2)-beta-D-glucuronopyranoside-6-O-butyl ester]-28-O-beta-D-glucopyranoside, adinaic acid 3 beta-O-[beta-D-glucopyranosyl(1-->2)-beta-D-glucopyrnaosyl]-(28-->1)-beta-D-glucopyranosyl(1-->6)-beta-D-glucopyranosyl ester, 27-hydroxyursolic acid 3 beta-O-[alpha-L-rhamnopyranosyl (1-->2)-beta-D-glucopyranosyl(1-->2)-beta-D-glucuronopyranoside-6-O-methyl ester]-28-O-beta-D-glycopyranoside. Their structures were elucidated by spectral methods, especially with the aid of 2D NMR techniques. Their complete assignments of the H-1 and C-13 NMR signals were carried out.展开更多
