摘要
目的:研究冬虫夏草及其类似品的HPLC指纹特征分析方法。方法:对冬虫夏草及其类似品共13个样本进行HPLC测定,结果分别采用相似度评价和采用轮廓图、雷达图、星座图等方法进行多变量二维平面比对分析。结果:相似度分析可综合量化样本的相似程度,轮廓图、雷达图、星座图等图示则能直观展示品种间的分类和特点。结论:相似度分析和轮廓图、雷达图、星座图等多变量图示的综合应用更加有利于指纹图谱的评判和指纹特征解析。
Objective： To study on HPLC fingerprint characteristic analysis of Cordyceps sinensis and its similar products. Methods： To determinate 13 samples of Cordyceps sinensis and its similar products by HPLC, and analyze the HPLC results with similar appraisal method and graphical methods of multivariate sample in two dimensional plane such as the methods of profile, radar chart and constellation graph. Results： The similar appraisal method might synthesize the similar degree in quantification, while the graphical methods such as profile graph, radar chart and constellation graph could show more details about the classification and the characteristic of varieties directly. Conclusions ： We recommend the combined application of similar appraisal method and the graphical methods due to its advantages on the judgment and characteristic analysis of fingerprint.
