HPLC fingerprint analysis of Cacumen Platycladi / 中成药

ABSTRACT

AIM: To establish a method of fingerprint analysis on Cacumen Platycladi. METHODS: HPLC was adopted with ZORBAX Eclipse XDB-C18,acetonitrile-0. 1% H3PO4 solution (gradient alution) as a mobile phase and detection wavelength at 254 nm,flow rate was 1 mL/min,and colum temperature was at 40 ℃. RESULTS: Eleven common peaks were separated from 14 batches of Cacumen Platycladi. As compared with standard sample,quecitroside and quecitin were checked out. CONCLUSION: The method is reliable,accurate and can be used as a quality control method for Cacumen Platycladi.
