Chemistry, toxicity and antifeedant activity of the resin of Flourensia thurifera

Abstract

The resin extract from leaves and stems of Flourensia thurifera displayed high levels of activity in the brine shrimp (Artemia salina) and antifeedant disk-choice (Spodoptera littoralis) bioassays. A bioassay-guided fractionation of the extract led to the isolation of nine known aromatic compounds (1-9) including coumarins, chromenes, a benzofuran, a flavonoid and p-coumaric acid derivatives. The results of bioassays on the pure compounds are discussed.
