Three bisdesmosidic triterpenoid saponins I-III, have been isolated from the flowers of Lonicera macranthoides Hand. -Mazz. By spectral (IR, MS, 1H-NMR and 13C-NMR) and chemical methods, I was proved to be identical with the known dipsacoside B, II and III were new compounds named macranthoidin A and macranthoidin B. Their structures were identified as follows: The prosapogenin of II, macranthoside A(IIb), was elucidated as 3-O-beta-D-glucopyranosyl-(1-3)-alpha-L-rhamnopyranosyl-(1-2)-alpha-L- arabinopyranosyl 3 beta, 23-dihydroxyl-olean-12-en-28-olic acid, II was established as 3-O-beta-D-glucopyranosyl-(1-3)-alpha-L-rhamnopyranosyl-(1-2)-alpha-L- arabinopyranosyl 3 beta,23-dihydroxyl-olean-12-en-28-O-beta-D-glucopyranosyl-(1-6)-beta-D- glucopyranoside. The prosapogenin of III, macranthoside B(IIIb), was elucidated as 3-O-beta-D-glucopyranosyl-(1-4)-beta-D-glucopyranosyl-(1-3)-alpha-L- rhamnopyranosyl-(1-2)-alpha-L-arabinopyranosyl 3 beta,23-dihydroxyl-olean-12-en-28-olic acid, III was established as 3-O-beta-D-glucopyranosyl-(1-4)-beta-D-glucopyranosyl-(1-3)-alpha-L- rhamnopyranosyl-(1-2)-alpha-L-arabinopyranosyl 3 beta,23-dihydroxyl-olean-12-en-28-O-beta-D-glucopyranosyl-(1-6)-beta-D- glucopyranoside. IIb and IIIb have not been reported in the literature.
