The fractions of hexane and dichloromethane extraction from marupa´ (Simaruba amara) and (Bertholletia excelsa) leaves were analyzed by HT-HRGC (high temperature high resolu- tion gas chromatography) and HT-HRGC coupled to mass spectrometry (HT-HRGC-MS).

Several compounds can be characterized including unusual high molecular weight com- pounds.
