Two epimeric flavalignans from Trichilia catigua (Meliaceae) with antimicrobial activity

Z Naturforsch C J Biosci. 2002 May-Jun;57(5-6):483-8. doi: 10.1515/znc-2002-5-614.

Abstract

A mixture of flavalignan cinchonains Ia and Ib was isolated from the bark of Trichilia catigua. The structures were established on the basis of spectroscopic data of the natural products and their methylated derivatives including 2D NMR experiments, and compared with data in the literature. These flavalignans exhibited antibacterial activity against Bacillus
