In a complete examination of the aerial stems of F. imbricata (Ruiz and Pa von), the following substances have been isolated a neutral essential oil which gave a negative reaction for furfuraldehyde; an ester (M.P. 77-5-78[degree]); palmitic acid; a phytosterol (M.P. 134[degree]); a new unsaturated alcohol, C26H42O (B.P. 145[degree]/25 mm.), possessing the fragrantodor of thedrug; traces of unsaturated acids; arachidic acid; scopoletin; a basic compound which gave an amorphous picrate (M.P. 125[degree] with decomposition); a sugar giving d-phenylglucosazone; a new glucoside of scopoletin, C16H18O9.2H2O (M.P. 226-228[degree]), designated fabiatrin; and an amorphous substance possessing the properties of a saponin.
