Abstract

OBJECTIVE To study the chemical constituents of the essential oil from the seeds of Schisandra chinensis (Truze.)Baill.METHODS The essential oil was obtained by steam distillation.The chemical components were separated and identified by GC MS.The relative content of each component was determined by area nomalization.RESULTS 44 peaks were separated within 30 min and 27 of them were identified representing 95.13% of the total contents.CONCLUSION The main constituents of the essential oil from the seeds of Schisandra chinensis were found to be Copaene, α Farnesene and α Cubebene.Some components such as δ Selinene,Germacrene B and Germacrene D,etc.,have not been reported before.The chemical composition of the essential oil from the seeds of Schisandra chinensis are not same as those of the essential oil from the fruits studied before.
