ABSTRACT
<p><b>OBJECTIVE</b>To develop a HPLC method for the determination of arbutin, bergenin and catechin in Chinese herb Bergenia, and to provide a scientific basis for evaluating the quality and reasonable utilization of the herb.</p><p><b>METHOD</b>The HPLC analysis was achieved by using a C18 column and methanol-water as the mobile phase, with a flow rate of 1.0 mL min(-1), and detected by UV at 275 nm. The contents of arbutin, bergenin and catechin in the different parts of axial root, fibrous root and blade from Bergenia purpurascens and B. crassifolia.</p><p><b>RESULT</b>The contents of arbutin, bergenin and catechin have a few difference in B. purpurascens and B. crassifolia, and varies significantly in the different part of axial root, fibrous root and blade from some species. The contents of bergenin are higher in axial root, fibrous root, and the content of arbutin is higher in blade.</p><p><b>CONCLUSION</b>This HPLC method can be used to determine simultaneously the content of arbutin, bergenin and catechin, and can establish a foundation for scientific study and evaluating the quality of species in Bergenia.</p>
