[Methods]Welch Ultimate XB-C18( 5 μm,250 mm ×4. 6 mm) chromatographic column was adopted,and the mobile phase was acetonitrile-0. 1% phosphoric acid aqueous solution for gradient elution,the detection wavelength was 328 nm,the column temperature was 25 ℃,the similarities of 18 different batches of medicinal materials were evaluated,and the HPLC fingerprint chromatogram of S. paniculata Wall. ex DC. was set up. [Results] The RSDs of precision,repeatability and stability of HPLC fingerprint of 18 batches of S. paniculata Wall. ex DC. medicine materials were all less than 3%;HPLC reference fingerprint of the medicine materials was established.[Conclusions]HPLC fingerprint was established,its data were stable and reliable,and the method was simple and efficient,which could provide reference for the quality evaluation of Zhuang medicine S. paniculata Wall. ex DC.展开更多
