Saponins from Verbascum nigrum.
Two triterpene saponins have been isolated from the inflorescences of Verbascum nigrum. Their structures were determined by chemical and spectral methods as 3-O-([alpha-L-rhamnosyl-(1-->4)-(beta-D-glucopyranosyl-(1-->3)]-be ta-D-glucopyranosyl]-(1-->2)-beta-fucopyranosyl)-13 beta,28-epoxyolean-11-ene-3 beta,23-diol and 3-O-([alpha-L-rhamnosyl-(1-->4)-(beta-D-glucopyranosyl-(1-->3)-bet a-D- glucopyranosyl]-(1-->2)-beta-fucopyranosyl)-11-methoxy-olean-12-en e-3 beta,23,28-triol.
