Abstract

Guaiacin A and B, two new saponins, have been isolated from the leaves of G. officinale and were characterised on the basis of 13C-NMR and FAD mass spectroscopy as 3-O-(β-D-glucopyranosyl (1→3)-α-L-arabinopyranosyl]-30-nor-olean-12,20(29)-dien-28-O-β-D-glucopyranosyl ester (1) and 3-O-[D-glucopyranosyl-(1→3)-α-L-arabinopyranosyl] oleanolic acid-28-O-β-D-glucopyranosyl ester (2).
