Massworks^(TM)技术结合气相色谱/质谱联用分析黄花蒿挥发油成分

Analysis of volatile oil of Artemisia annua L. by Massworks^(TM)technology and gas chromatography / mass spectrometr

运用气相色谱/质谱联用技术(GC/MS)对甘肃永登产黄花蒿挥发油化学成分进行了分析。结合Massworks TM质谱解析软件及NIST谱库检索等手段,确定了黄花蒿挥发油中33种挥发性成分,主要为侧柏酮、桉树醇、邻异丙基甲苯、β-蒎烯、蒿酮、双戊烯和樟脑等。结果显示,Massworks TM技术提供的模拟精准分子量信息对未知化合物的确定具有非常重要的意义,可以为单四级杆质谱确定未知化合物提供重要的依据,可提高谱库检索定性的可靠性。

The constituents of the Artemisia annua L. volatile oil from Yongdeng of Gansu were analyzed by GC/MS,MassworksTMsoftware and NIST library. There were 33 kinds of components determined in the Artemisia annua L. volatile oil, mainly for thujone, eucalyptus alcohol, isopropyl toluene, β- pinene, artemisia ketone,dipentene,camphor and so on. The results showed that MassworksTMtechnology had very important significance to provide accurate molecular weight information of unknown compound. It could provide a strong basis to identify unknown compounds which was obtained by the low-resolution quadruple mass spectrometer,and meanwhile could improve the reliability of spectral library search.
