应用裂解-高分辨气相色谱-模式识别技术对五个不同地区的55个贝母类样品进行了分类研究,从裂解-高分辨气相色谱图中选取了19个特征峰作为分类指标,应用主成分分析法和SIMCA法进行了分类识别,有效地区分了贝母类样品的来源。本法操作简易、快速,无需化学预处理,所得结果可靠,是中药分类分析的一种有效技术。 The pyrolysis-high resolution gas chromatography-pattern recognition technique was used to classify 55 Fritillaria samples from five different regions. From the pyrolysis-high resolution gas chromatogram, 19 characteristic peaks were selected as classification indicators, and the main components were applied. Analytical methods and SIMCA methods were used to classify and identify the source of fritillaria samples. This method is simple and fast, does not require chemical pretreatment, and has reliable results. It is an effective technique for the classification and analysis of traditional Chinese medicine.
