Eclalbatin, a triterpene saponin from Eclipta alba.
From the whole plant of Eclipta alba, a new triterpene saponin, named eclalbatin, together with alpha-amyrin, ursolic acid and oleanolic acid were isolated. The structure of eclalbatin has been established as 3-O-beta-D-glucopyranosyl-3-beta-hydroxy-olean-12-en-28-oic acid, 28-O-beta-D-arabinopyranoside (1) on the basis of chemical and spectral data.
