Özet: A chemical investigation of the aerial parts of Launea resedifolia (O.K.) afforded four flavonoids, apigenin 1, luteolin 2, apigenin 7-O-β-glucoside 3and apigenin 7-O-β-glucuronide 4. The structures of the isolated compounds were established by chromatographic behaviour and by means of UV, NMR and MS spectral analysis. Moreover, the antimicrobial activity of two isolated flavonoids 3, 4 and the n-BuOH extract against eleven bacteria and one fungus was studied. It was found that the most powerful effect was against Morganella morgani; Streptococcus Sp; Enterobacter Sp. and Proteus mirabilis.
