Study on HPLC Fingerprint of from Guangxi Zhuang Autonomous Region
Objective: RP-HPLC fingerprint of Sophora tonkinensis grown in Guangxi Zhuang autonomous region was established. Method : A gradient separated method was applied on C18 column at 25 ℃ with methanol-water as mobile phase. Reference material was oxymatrine. Flow rate was 1.0 mL ·min-1; detection wavelength was set up at 220 nm and changed to 280 nm after 24 min. Result : The results showed that this method had a good repeatability and precision. Conclusion : This result can provide scientific data for analyzing the quality control of Sophora tonkinensis.
