Further applications of "home made" SFE systems. II. South American plants. The Laboratório de Cromatografia, IQSC-USP, has been developing joint research projects with other research groups from Brazil and Latin America, aiming a future implementation of SFE (supercritical fluid extraction) in these laboratories. In the present work, some of the results obtained in the cooperation with researchers from Chile and Venezuela, focused to SFE of potential economical interest compounds, active compounds or toxic molecules, are presented: triglycerides, fatty acids, flavonoids, alkaloids, etc. Native plants from Chile and Venezuela, belonging to several families (Leguminosae, Chrysobalanaceae, Annonnaceae, etc.) were studied, some of them never studied by conventional phytochemical methods. The utilization of SFE along as HRGC-EM (high resolution gas chromatography - mass spectrometry) or HPLC-DAD (high performance liquid chromatography - diodearray detector) allowed the identification of some compounds, starting from small amounts of plant material; these data are of great significance to the chemical characterization of the studied species.
