裂解气相色谱法具有快速、灵敏、准确等特点,已被广泛应用于高聚物、生物大分子相微生物等的鉴别和分类,在中药材分析中的应用也有报道。我们在研究工作中发现,同属及同种不同产地中药材的裂解色谱图十分相似,用肉眼很难区别,为此,我们首次将数值分析技术引入中药材裂解色谱图的解析,并对五加科中几种名贵中药材和百合科麦冬进行了分析鉴别,结果令人满意,此法可望为中药材鉴别提供新的途径。 Pyrolysis gas chromatography has the characteristics of rapid, sensitive and accurate. It has been widely used in the identification and classification of polymers, biological macromolecules and other microorganisms, and the application in the analysis of Chinese medicinal materials has also been reported. We found in the research work, the same genus and the same origin of different parts of the Chinese herbal medicine cleavage chromatogram is very similar, with the naked eye is difficult to distinguish, therefore, for the first time we introduced the numerical analysis of traditional Chinese medicine cleavage chromatogram analysis, and five plus Section of several valuable Chinese herbal medicines and Radix Ophiopogon for analysis and identification, the results are satisfactory, this method is expected to provide a new way for the identification of Chinese herbal medicines.
