摘要
据化学计量学分辨方法,提出一个用气相色谱-质谱联用法定性定量分析仙鹤草中挥发油成分的方法。对重叠色谱峰采用直观推导式演进特征投影法进行分辨,从而获得每一组分的纯色谱和质谱,对每一组分纯质谱在NIST质谱库进行相似性检索并进行定性分析,用总体积积分法进行定量分析。从仙鹤草挥发油样品中共分离出56个色谱峰,鉴定出其中50个组分,占挥发油总含量的90.53%,其主要组分为醇和单萜类化合物,分别占总化合物的50.58%和18.34%。采用该方法可为进一步研究和开发仙鹤草的药用价值提供有用信息。
Based on chemometric resolution methods, a method for qualitative and quantitative determination of the volatile components in Agrimonla Pilosa Ledeb was developed by chromatography-mass spectrometry. The overlapping chromatographic peaks were resolved into pure chromatograms and spectra with heuristic evolving latent projections （HELP）, qualitative analysis was performed by similar search in NIST library with the obtained pure mass spectrum of each component and the quantitative results were obtained by calculating the volume of total two-way response. The results show that 56 components are separated and 50 components are identified, accounting for 90.53% of the total content. The main components are alcohols and monoterpene, accounting for 50.58% and 18.34% of the total content, respectively. The present method can be used to provide useful information for further study and development of Agrimonla Pilosa Ledeb.
