[HPLC characteristic chromatographic profile of Sarcandra glabra].

ABSTRACT

OBJECTIVE: To develop the characteristic chromatographic profile of Sarcandra glabra by HPLC for its quality control. METHOD: The HPLC analysis was performed on an Agilent Zorbax Eclipse XDB-C18 column (4. 6 mm x 250 mm, 5 microm) with column temperature at 40 degree C. The mobile phase was consisted of water containing 0. 5% formic acid and acetonitrile to methanol (19) in gradient mode, and the detection wavelength was set at 344 nm. RESULT: A common mode of the HPLC characteristic chromatographic profile has been establised. There were 20 common peaks , seven of which were identified, and 46 samples from different habitats were classified into five groups based on principal component cluster analysis. CONCLUSION: The method was time-saving and can represent the chemical information and provide a scientific basis for quality control of S. glabra.
