| Abstract: | OBJECTIVE To analyze the chemical components of supercritical fluid CO2(SFE-CO2) extraction of the aerial parts of Synurus deltoides(Ait.) Nakai.METHODS The aerial parts of S.deltoides was extracted with SFE-CO2,and analyzed by GC-MS.RESULTS The SFE-CO2 extraction was grey green oil,and its yield was 1.57% 22 chemical components were identified by GC-MS.CONCLUSION The main components were lupeol,lup-20(29)-en-3-ol,acetate,(3 β),tetratetracontane,olean-12-en-3-one,stigmast-5-en-3-ol,lup-20(29)-en-3-one,etc. |
