Abstract: To study the chemical and bioactive characteristics of bergenin derivatives which were purified from Saxifraga melanocentra Franch ., a new gallic acid ester of bergenin , 11- O- (4 - O-methylgalloyl) bergenin (1) was isolated from the aerial parts of Saxifraga melanocentra Franch ., and its structure was established mainly on the basis of 1D and 2D NMR spectroscopic analysis . It showed weak inhibitory activity against HCV NS3 serine protease with IC50 of 0.32mg/ml .

Key words: HCV NS3 serine protease
