Herniaria saponin B. a novel triterpenoid saponin from Herniaria fontanesii.
The aerial parts of Herniaria fontanesii have yielded a new saponin named herniaria saponin B. Its structure was characterized by means of mass spectrometry. NMR techniques, and chemical analysis gave 28-O-[alpha-L-rhamnopyranosyl-(1-->2)-[(alpha-L-rhamnopyranosyl-(1--> 3)]-beta-D-xylopyranosyl (1-->2)-beta-D-fucopyranosyl) ester of 3-O-[beta-D-glucopyranosyl uronic-(1-->4)-alpha-L-rhamnopyranosyl]-2 beta. 3 beta-16 alpha-trihydroxy-olean-12-ene-23, 24-dioic acid.
