石菖蒲挥发油的气相色谱指纹图谱研究

Study on the GC Fingerprints of Grassleaf Sweetflag Rhizome Aetherolea

目的:建立石菖蒲挥发油的气相指纹图谱,以控制其质量。方法:进样口温度为250℃,检测器温度为280℃,载气为氮气, 流速为1．3ml／min,并采用程序升温对10批石菖蒲中挥发油成分的气相色谱进行分析。结果:共标出6个特征峰,其平均峰面积之 和为总峰面积的(75．4±13．7)％。结论:本方法精密度、重现性、稳定性好,各挥发油成分分离较好,所建立的指纹图谱可作为石菖 蒲的质量控制依据。

OBJECTIVE： To establish the GC fingerprints for Grassleaf sweetflag rhizome aetherolea and to control its quality.METHODS： The temperature at the mouth of the sample injector was 250℃ and that of the detector was 280℃ , the carrier gas was nitrogen gas and the flow rate was 1.3ml/min, the GC of aetherolea in 10 batches of Grassleaf sweetflag rhizome was analyzed by adopting temperature programming.RESULTS：Altogether 6 peaks were marked out, the sum total of the average peak area of which made up（75.4± 13.7）% of the total.CONCLUSION： The method is of high degree of precision, reproducibility, stability, the resolving of each component in the aetherolea is good, the established fingerprints can be used as one of the quality control index for Grassleaf sweetflag rhizome.
