Investigation on Kalimeris integrifolia resulted in two compounds by means of various chromatographic techniques (silica gel, Sephadex LH-20, RP-LC and Pre-HPLC). Their structures were determined as 5,8-dihydroxy-2-(3-hydroxy- 4,5-dimethoxyphenyl)-6,7-dimethoxy-4H-chromen-4-one (1) and 5-hydroxy-6,7-dimethoxy-2-(4-methoxyphenyl)-4-oxo-4H- chromen-8-yl 2-methylbutanoate (2) on the basis of extensive spectroscopic analyses including MS, IR, UV, 1D- and 2D- NMR. Among them, compounds 1 and 2 are two new flavonoids, named as kalinturflavone A (1) and kalinturflavone B (2).

Key words: Kalimeris integrifolia, Asteraceae, chemical constituent, flavonoids
