目的建立一种准确、快速,同时测定蚊香中4种有效成分的气相色谱-质谱联用法(GC-MS),并且分析比较其中成分及使用。方法采用Rtx-5MS色谱柱(30 m×0.25 mm×0.25μm),程序升温,EI源,对蚊香中4种有效成分即烯丙菊酯、炔丙菊酯、四氟甲醚菊酯、氯氟醚菊酯进行GC-MS分析,并对其进行定性鉴定和定量分析。结果该分析方法的线性相关系数为0.999 99,回收率为94.3%~98.7%,相对标准偏差为1.96%。结论用此方法检测了蚊香中4种有效成分的含量,分离效果非常好,准确度和精密度都非常高,快速而简便,同时达到了定性鉴定和定量分析的要求。
Objective To establish an accurate and rapid determination of 4 active ingredients in mosquito coils by gas chromatography-mass spectrometry (GC-MS), and analyze the composition and use of them. Methods Four active constituents of mosquito-repellent incense (allergens, pyrethroids, tetramethrin, chlorpromazine, chlorpromazine) were determined by Rtx-5MS column (30 m × 0.25 mm × 0.25 μm) Hesperidin GC-MS analysis, and its qualitative identification and quantitative analysis. Results The linear correlation coefficient of this method was 0.999 99, the recovery was 94.3% ~ 98.7%, and the relative standard deviation was 1.96%. Conclusion This method was used to detect the content of four active ingredients in mosquito coils. The separation effect is very good. The accuracy and precision are very high. It is fast and simple, and meets the requirements of qualitative identification and quantitative analysis.
