Results: the yield rate of the collected volatile oil of artemisia indica and artemisia feddei was 0.32%, 0.29%, respectively. the main constituents of them were as follows: eucalyptol, camphor, borneol, terpineol, cubebene, caryophyllene, caryophyllene oxide, germacrene d, etc, which was similar to the constituents of volatile oil from artemisia argyi. but the contents of volatile oil were different in different medicinal materials. longiverbenone with high content in artemisia feddei was can not be detected in artemisia indica and artemisia argyi.

结果：广西产五月艾与细叶艾挥发油的得率分别为0.32%、0.29%；五月艾、细叶艾和艾叶挥发油中均含有桉油精、樟脑、龙脑、松油醇、荜澄茄油烯、石竹烯及其氧化物、大根香叶烯d等药效成分，但各成分在不同药材中的含量存在一定差别；此外，细叶艾挥发油中含量较高的长叶马鞭烯酮在五月艾和艾叶挥发油中均未检出。

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.

五味子种子挥发油的主要成分为烯，α-金合欢烯、α-荜澄茄油烯，与以前报道的果实挥发油成分有所不同。

The main volatile compounds were recorded, such as à-Cubebene (1.470%), Copaene (3.686%), C-Muurolene (3.152%, Eremophila-1(10), 11-diene (30.145%), Longifolene-(V4)(5.653%), Cadina-3, 9-diene (15.152%), Copaene (1.232%). The SPME fiber shows better selectivity and sensitivity toward some fragrance compounds comparing with other method.

主要挥发组分如：荜澄茄à-Cubebene (1.470%)、胡椒烯Copaene (3.686%)、衣兰油烯C-Muurolene (3.152%)、雅槛兰－1(10)，11-二烯Eremophila-1(10)，11-diene (30.145%)、长叶松萜烯Longifolene-(V4)(5.653%)、杜松－3，9-二烯Cadina-3，9-diene (15.152%)、古巴烯Copaene (1.232%)等。
