[Study on HPLC-FPS of Pueraria of different sources].

OBJECTIVE: To make comparative study on HPLC-FPS of several kinds of Pueraria lobata and P. thomsonii from different sources. METHOD: Kromasil C18 column was used, with mixture of acetonitrile and water as mobile phase in a gradient mode. The wavelength of measurement was 250 nm. RESULT AND CONCLUSION: The fingerprints of P. lobata and P. thomsonii were obtained. This method can be used to identify P. lobata and P. thomsonii from different sources conveniently, and it may be practically valuable for the quality control of sample for P. lobata or P. thomsonii and its preparation.
