Objective:Gallic acid of Saxifraga stolonifera in Guizhou was determined by HPLC.The difference of the quality of S.stolonifera in Guizhou was studied by the current quality criteria of S.stolonifera.It aims at providing a technological basis of improving the method of controlling the quality of S.stolonifera and the standardi-zation planting.Method:The content of bergenin and gallic acid in S.stolonifera was determined by HPLC.Result: The content of bergenin of S.stolonifera was higher than 0.080%
the minimum of current quality criteria
and the average content of gallic acid was 0.121%.The content of bergenin and gallic acid in S.stolonifera was different from various habitats
various collection time and various processing methods.Conclusion: The quality of S.stolonifera was evaluated by using various componential indices and to provide a standardized planting technological basis for GAP and improve the method of quality control of S.stolonifera.
