ABSTRACT
Objective:To establish the fingerprint of Bupleuri Radix with Ultra High Performance Liquid Chromatography (UPLC) method and combining Principal Component Analysis to evaluate the quality of Bupleuri Radix in different areas. Methods:Acquity UPLC BEH-C 18 (2.1 mm×100 mm, 1.7 μm) column was used with acetonitrile (A)-water (B) solution, gradient elution. The column temperature was 30 ℃, the flow rate was 0.3 ml/min, and the detection wavelength was 200 nm, injection volume 5 μl. Results:There were 7 common peaks in the UPLC fingerprints of 10 batches of medicinal materials, and the similarity was 0.940-0.975. Through the principal component analysis, the cumulative contribution rate of three main component factors was 90.977%,and comprehensive score of S5 (Hubei) was the highest with the best quality.Conclusions:There are certain quality differences of different areas in Bupleuri Radix. Through the combination of fingerprint and principal component analysis, it can provide reference for quality control, development and application of Bupleuri Radix.
