| Abstract: | 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 ofUvaria 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 tvolatile oils extracted by SFE-CO2 and steam distillation. |
