Objective:
To establish a HPLC fingerprint analysis method for identification of Bupleurum chinense of Hebei Province and compare the fingerprints of Radix Bupleuri collected from different habitats so as to establish a sensitive and specific method for controlling the quality of Radix Bupleuri.
Methods:
The HPLC-UV fingerprints of Radix Bupleuri from different habitats were obtained from Waters 1525 instruments. The HPLC separation was performed on a C18 analytical column gradient eluted with a mixture consisting of acetonitrile and water at a flow rate of 1.0 ml/min with UV detector at 203 nm. The temperature of column was 30 degrees C.
Results:
The mutual mode of HPLC-UV fingerprints was set up, and the similar degrees to the crude drugs of different habitats were compared.
Conclusion:
It is simple and quick to differ Bupleurum chinense from different habitats with the method that can be used as a quality control item for Radix Bupleuri.
