Antimicrobial activity of four annual Papaver species growing in Turkey

Abstract

The extracts obtained from aerial parts of four annual Papaver (Papaveraceae) species from sections Argemonidium (P. argemone L. subsp. davisii Kadereit) and Rhoeadium (P. clavatum Boiss. & Hausskn. ex Boiss., R dubium L. subsp. lecoqii var. lecoqii (Lamotte) Syme Kadereit and P rhoeas L.) have been investigated for antimicrobial activity using a microbroth dilution technique. The antimicrobial activity of these species is reported for the first time. The petroleum ether and diethyl ether extracts of R dubium subsp. lecoqii showed antibacterial activity against Staphylococcus aureus (MIC: 9.76 and 19.52 mu g/mL, respectively). The diethyl ether and chloroform extracts of P. argemone subsp. davisii and diethyl ether, chloroform and acetone extracts of P. rhoeas had activity against S. aureus with a MIC value of 39.06 mu g/mL.
