External flavone aglycones in the overground parts of Veronica chamaedrys L. (Scrophulariaceae) have been analysed by isocratic reversed-phase high performance liquid chromatography. Luteolin, apigenin, luteolin-3'-methyl ether and scuterallein-6,4'-dimethyl ether have been identified. The latter compound is a new flavonoid identified in Veronica genus.
