  Four new triterpenoid saponins were isolated from the roots of Adina rubella Hance. They were characterized as adinaic acid 3 β-O-[α-L-rhamnopyranosyl(1→2)-β-D-glucopyranosyl(1→2)-β-D-glucurono-pyranoside-6-O-methyl ester]-28-O-β-D-glucopyranoside, adinaic acid 3 β-O-[α-L-rhamnopyranosyl(1→2)-β-D-glucopyranosyl(1→2)-β-D-glucuronopyranoside-6-O-butyl ester]-28-O-β-D-glucopyranoside, adinaic acid 3 β-O-[β-D-glucopyranosyl(1→2)-β-D-glucopyrnaosyl]-(28→1)-β-D-glucopyranosyl(1→6)-β-D-glucopyranosyl ester, 27-hydroxyursolic acid 3 β-O-[α-L-rhamnopyranosyl(1→2)-β-D-glucopyranosyl(1→2)-β-D-glucuronopyranoside-6-O-methyl ester]-28-O-β-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.

  Twelve triterpenoid saponins, including six new, were isolated and identified from the aerial parts of Fagonia glutinosa. The new saponins were characterised as 3-O-[beta-D-glucopyranosyl(1-->2)][beta-D-glucopyranosyl(1-->3)]-alpha-L - arabinopyranosyl-27-hydroxy oleanolic acid 28-O-beta-D-glucopyranosyl ester, 3-O-[beta-D-glucopyranosyl(1-->3)]-alpha-L-arabinopyranosyl ursolic acid, 3-O-alpha-L-arabinopyranosyl ursolic acid 28-O-beta-D-glucopyranosyl ester, 3-O-[beta-D-xylopyranosyl(1-->2)][beta- D-glucopyranosyl(1-->3)]-alpha-L-arabinopyranosyl ursolic acid, 3-O-[beta-D-glucopyranosyl(1-->2)][beta-D- glucopyranosyl(1-->3)]-alpha-L-arabinopyranosyl ursolic acid 28-O-beta-D-glucopyranosyl ester and 3-O-[beta-D-glucopyranosyl(1-->2)][beta-D-glucopyranosyl(1-->3)]-alpha-L - arabinopyranosyl-27-hydroxy ursolic acid 28-O-beta-D-glucopyranosyl ester. The structures of the saponins were established by spectral and chemical evidences. The assignments of the NMR signals were performed by means of HOHAHA, 1H-1H COSY, ROE, HMQC and HMBC experiments.
