Abstract

A phytochemical investigation of Scorzonera veratrifolia Fenzl (Asteraceae) yielded two new 3-benzylphthalides, scorzoveratrin (1) and scorzoveratrozit (2), together with five known compounds, chlorogenic acid (3), chlorogenic acid methyl ester (4), cryptochlorogenic acid (5), 4,5-dicaffeoylquinic acid (6) and 3,5-dicaffeoylquinic acid (7). All secondary metabolites were assigned using physicochemical and spectroscopic data. The known compounds 3-7 were isolated for the first time from this species.
