摘要
应用同步热分析-傅里叶变换红外光谱-气相色谱/质谱联用法对艾叶样品的热分解过程和热解产物进行了研究。分别在氮气、氧气气氛下监测艾叶样品在程序升温下的热失重和红外变化,并将274和312℃时的热解产物切入到气相色谱/质谱仪进行同步检测和分析,两种气氛下共检测到了41个主要化合物,不同气氛下下检测到的化合物的种类是有差别的,在氮气气氛下检测到29个主要化合物,其中γ-松油烯、α-松油醇、马鞭草烯醇、对伞花烃、萜品油烯等含量较高。在氧气气氛下,共检测到27个主要化合物,其中对聚伞花素、γ-松油烯等含量较高。本方法操作比较简单,不需要对样品进行前处理,并可以对热解产物进行实时检测,为艾叶的研究提供了一种新的方法。
The thermal decomposition process and the pyrolytic products under thermogravimetry of Artemisia argyi was investigated by synchronous thermal analysis/fourier transform infrared spectroscopy and Gas chromatography mass spectrometry.The thermogravimetric and infrared changes of Artemisia argyi samples under temperature programmed were monitored under nitrogen and oxygen atmosphere,respectively.The pyrolysis products at 274 and 312℃ were synchronously analyzed by gas chromatography/mass spectrometry,and 41 main compounds were found under the two atmosphere.The types of compounds detected in different atmospheres are different.29 main compounds were detected in nitrogen atmosphere.The contents of γ-terpinene,α-terpineol,verbenenol,paraffinic hydrocarbon,terpene olene are high.A total of 27 main compounds were detected in oxygen atmosphere.The content of paracymosin and γ-terpinene are high.This method is simple to operate and can detect the pyrolysis products in real time.It provides a new rapid analysis and test method for exploration of Artemisia argyi.
