Supercritical fluid extraction of essential oil from the fruits of Bupleurum chinense DC. and their characterization by GC/MS

摘要

Objective:Aim To analyze the chemical constituents of essential oil from the fruits of Bupleurum chinense DC.Methods:Essential oil from the fruits of Bupleurum chinense DC.was extracted by using supercritical fluid extraction (SFE),and the chemical constituents to be identified by GC/MS spectrum.Results:The yield of essential oil from the fruits of Bupleurum chinense DC.by SFE was 6.60%(V/W)and 73 components were identified in this oil.Conclusions:The essential oil from the fruits of Bupleurum chinense DC.was produced for the first time,and its yield was 3 times more than its root,the relative contents of linoleic acid,cetyl acetate,ethyl linoleate,(-)-caryophyllene oxide are 34.85%,16.63%,2.64%,1.81% apart in this essential oil.Phytol,cetyl acetate,ethyl linoleate,(-)-caryophyllene oxide were confirmed for the first time from the genus of Bupleurum.
