In-vitro evaluation of the antimicrobial activities of Enantia chlorantha Oliv. extractives.

A bioactivity-directed fractionation of the root-and stem-barks of Enantia chlorantha resulted in the isolation of palmatine chloride 1 and jatrorrhizine chloride 2 as the major antimicrobial constituents. MIC determinations indicated that these compounds were superior to those of well established broad spectrum antibiotics against some of the organisms used.
