摘要:

利用GC MS法对四合木茎叶的石油醚提取物进行了成分鉴定。鉴定出40种化合物，包括烷烃类化合物8种、羧酸类化合物11种、酯类化合物9种、萜类化合物2种、甾体类化合物2种、醇类化合物4种，占样品总量的80.5%。其中相对含量最高的3种成分依次为油酸(15.33%)、β 谷甾醇(9.12%)和十八碳二烯酸甲酯(7.24%)。β 谷甾醇可能是四合木具有抗虫性的主要成分。

Abstract:

The composition of petroleum extraction of the stem and leaf of T.mongolic was identified by GC MS. 40 compounds were identified. They include alkane(8 kinds)，Carboxylic acid(11 kinds)，Ester(9 kinds)，Terpene(2 kinds)，Steroid(2 kinds)，Alcohol(4 kinds)，which accounted for 80.5% of the total sample. The highest relatively content was Oleic Acid(15.33%)，the second was β Sitosterol with the content of 9.12% and the third was 9，12 Octadecadienoic acid，ethyl ester with the content of 7.24%.β sitosterol may be main insect resistance compound of Tetraena which have insect resistance.
