HPLC fingerprint of Rubus chingii Hu

AIM:To establish HPLC fingerprint for controlling the quality of Rubus chingii Hu. METHODS: Analysis was performed on Alltech C_(18) column(250 mm×4.6 mm,5 μm)with a mixture of acetonitrile and water as mobile phase in gradient mode,flow rate was 1.0 mL/min,wavelength at 211 nm. RESULTS: There were 15 common peaks in the HPLC fingerprints of Rubus chingii Hu.The RSD of precision and reproducibility lay within 5%. CONCLUSION: The method has good sensitivity and repeatability.This chromatographic fingerprint method can be used to controll the quality of Rubus chingii Hu.
