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).
