Abstract

Vicenine-2, cirsimaritin, salvigenin, diosmetin, desmethoxycentaureidin, 6-methoxy-luteolin 7,3,4- trimethylether, apigenin and luteolin, eight flavonoids were isolated for the first time from the aqueous methanolic extract of the aerial parts of Teucrium pilosum, The structures were established on the basis of chemical and spectroscopic (UV, 1H-, 13C-NMR) analyses. Biological activity was studied using agar diffusion and cytotoxicity tests.

Keywords: Lamiaceae, Teucrium pilosum, flavonoids, antimicrobial and cytotoxicity tests
