伸筋草挥发油成分的固相微萃取分析

Analysis of chemical constituents of volatileoils from lycopod herb

目的:分析伸筋草中挥发油化学成分。方法:采用固相微萃取-气相色谱-质谱联用法分析挥发油化学成分。结果:共分离出98个组分,鉴定了81个组分,用归一化法测定其百分含量,占总挥发油组分峰面积的97.80%。结论:主要成分是癸酸(10.63%)、β-马榄烯(6.60%)、反-石竹烯(7.29%)、白菖蒲油烯(23.77%)、α-古芸烯(3.38%)、α-姜黄烯(1.38%)、α-蛇床烯(1.67%)、δ-杜松烯(2.16%)、α-雪松醇(15.50%)等组分。

OBJECTIVE Onto analyze the volatile oil chemical composition from lycopodii herb. METHODS The volatile oil chemical composition was analyzed by SPME-GC-MS. RESULTS 98 components were separated from total essential oil and 81 components were identified by GC-MS. The amount of the components from the essential oil was determined by normalization method, these components is equivalent to about 97. 80% of the total essential oil. CONCLUSION The main chemical components are decanoic acid （10. 63%）, beta-maaliene （6. 60%）, trans-caryophyllene （7. 29%）, calarene （23. 77%）, alpha -gurjtmene （3. 38%）,alpha. -curcumene （1.38%）,alpha. -selinene （1.67%）,delta. -Cadinene （2. 16%,alpha. -Cedrol （15. 50%）et al.
