[Objective] To study the chemical components of volatile oils from leaves of Uvaria microcarpa Champ.ex Benth.[Method] Volatile oils were extracted from leaves of Uvaria microcarpa Champ.ex Benth by supercritical fluid CO2 extraction (SFE-CO2),and then their chemical components were separated and identified by GC-MS.[Result] 58 chromatographic peaks were isolated from leaves of Uvaria microcarpa Champ.ex Benth,among which 37 compounds were identified occupying 89.70% of the total volatile oils,mainly referred to linoleic acid,palmitic acid,mono (2-ethylhexyl) phthalate,bicyclogermacrene and benzoic acid.[Conclusion] There were obvious differences in chemical components of volatile oils extracted by SFE-CO2 and steam distillation.
