Klimek, B. | Lavaud, C. | Massiot, G.
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-(l leads to 4)-(beta-D-glucopyranosyl-(l leads to 3)-beta-D- glucopyranosyl]-(l leads to 2)-beta-fucopyranosyl)-13beta,28-epoxyolean-11-ene-3beta,23 -diol and 3-O-{[alpha-L-rhamnosyl-(l leads to 4)-(beta- D-glucopyranosyl-(l leads to 3)-beta-D-glucopyranosyl]-(l leads to 2)-beta-fucopyranosyl)-11-methoxy-olean-12-ene-3beta,23,28- triol.
