Constituents of the Leaves of Verbascum blattaria

Abstract

Phytochemical investigation of the dried leaves of Verbascum blattaria L. (Scrophulariaceae) led to the isolation and identification of five known compounds, E-harpagoside, laterioside, kaempferol 3-O-beta-D-glucopyranoside, bis(2-ethylhexyl)phthalate, and (28)-liquiritigenin. The structures of these compounds were determined by physical and spectroscopic data analysis. All compounds were isolated from V. blattaria for the first time.
