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.
目的
研究冬虫夏草及其混淆品的高效液相色谱指纹图谱特征分析。
方法
采用高效液相色谱法测定13个冬虫夏草及其混淆品样品，并用相似度评价方法及二维平面上多变量样本的图形方法（如轮廓图、雷达图和星座图法）对高效液相色谱结果进行分析。
结果
相似度评价方法能综合量化相似度，而轮廓图、雷达图和星座图等图形方法能更直观地显示品种分类及特征的更多细节。
结论
鉴于相似度评价方法和图形方法在指纹图谱判断及特征分析方面的优势，建议二者联合应用。
