OBJECTIVE： To establish HPLC fingerprint of Zhuang and Yao medicine Lespedeza formosa， and to provide reference for quality control of L. formosa from different producing areas. METHODS： Totally 10 batches of samples were collected from 5 producing areas as Guangxi Nanning， Guilin， Wuzhou and so on. HPLC fingerprints was established and similarity analysis was carried out by using “Similarity evaluation system of TCM chromatographic fingerprint” （2012 edition） software. The determination was performed on Inertsil ODS-3 column with mobile phase consisted of acetonitrile-0.2％ phosphoric acid solution （gradient elution） at the flow rate of 0.8 mL/min. The detection wavelength was set at 350 nm， and the column temperature was 35 ℃. The sample size was 10 μL. Common peaks were identified by comparing substance control. Cluster analysis and principal compoent analysis were performed by using IBM SPSS 21.0 statistical software. RESULTS： HPLC fingerprint was established， and 12 common peaks were calibrated. 3 common peaks were identified （common peak 8， 10， 11 were chafotalin， vitexin and isovitexin）. The similarity of 10 batches of samples were all higher than 0.9. Through cluster analysis， 10 batches of medicinal materials could be clutered into 2 groups. According to the principal component analysis， the cumulative variance contribution rate of the two principal component factors was 86.108％ （contribution rates of first principal components and second principal components were 66.891％ and 19.217％）. CONCLUSIONS： HPLC fingerprint of L. formosa is established successfully. The method is simple and easy to use， provides a reliable evalution method for quality control of L. formosa.
