Characterization of antibacterial flavonoids and stilbenes of the root extract of Anogeissus leiocarpus by UHPLC-MS-QTOF

Anogeissus leiocarpus occurs in savannas in tropical and subtropical regions of Africa and is used among traditional medicinal practitioners for treatment of various diseases, among them bacterial infections [1]. Eight flavonoids [2], methyl ellagic acid, ellagic acid [4, 5] and the ellagitannins castalagin and flagallonic acid [6] have been reported from the leaves and bark of A. leiocarpus. There are just a few investigations on the phytochemistry of the roots [1], however. This study has aimed on in depth investigations on the phytochemistry of the root part.
