OBJECTIVE
To develop a GC method to determine the content of caryophyllene in Eupatorium fortune.
METHOD
The samples were determined on a DB-1701 (0.32 mm x 30 m, 0.25 microm) quartz capillary column. And the sample was extracted with ethanol by the ultrasonic assisted extraction.
RESULT
The calibration curve of caryophyllene is liner over the range of 0.002-2.0 g x L (-1) (R2 = 1). The recovery was from 96.76% to 104.15%.
CONCLUSION
The method is accurate, simple with a good reproducibility. It can be used to control the quality of E. fortune.
目的
建立一种气相色谱法测定野马追中石竹烯的含量。
方法
采用DB-1701（0.32mm×30m，0.25μm）石英毛细管柱对样品进行测定。样品采用乙醇超声辅助提取。
结果
石竹烯在0.002 - 2.0 g·L⁻¹范围内校准曲线呈线性（R² = 1）。回收率为96.76%至104.15%。
结论
该方法准确、简便，重现性好。可用于控制野马追的质量。
