Study on HPLC Fingerprint and Pattern Recognition Method of Citri Sarcodactylis Fructus from Different Origins / 世界科学技术-中医药现代化

ABSTRACT

This study was aimed to establish fingerprints of Citri Sarcodactylis Fructus from different geographical origins,and to use the method of pattern recognition to compare the differences of Citri Sarcodactylis Fructus from different habitats.In this study,high performance liquid chromatography (HPLC) was used to establish fingerprints for 25 batches of Citri Sarcodactylis Fructus from 4 habitats.Furthermore,similarity evaluation,cluster analysis (CA) and principal component analysis (PCA) were performed.The results from established fingerprints showed that a total of 26 common peaks were pointed out and 4 peaks were identified as the common peaks.The CA and PCA can be used to compare Citri Sarcodactylis Fructus from different habitats.It was concluded that Cirri Sarcodactylis Fructus in near geographic origins had a higher similarity,while the different geographic origins had a higher difference.
