Objective: To compare the differences of bergenin content in different parts of S. stolonifera from different regions in Guizhou province

and provides the scientific basis for reasonable medication and quality control of S. stolonifera. Method: The bergenin content in different parts of S. stolonifera was quantitative analyzed by HPLC. Result: The difference of bergenin content in identical part of S. stolonifera from the different regions was significant

and the bergenin content in the different parts of identical S. stolonifera was different too; and that in leaves was better than in stems

which in the roots was the lest. Conclusion: The method for determination of bergenin in the different parts of S. stolonifera was established

which was exact

simple

fast

stable and reproducible so that may be used as one of the methods for quality evaluation of S. stolonifera.
