Abstract: From the aerial parts of Saxifraga melanocentra, ten compounds were isolated and identified with spectral analysis and compared with authentic samples as kaermpferol ( 1 ) , quercetin ( 2 ) , kaempferol-3- O-β-D-glucoside ( 3 ) , quercetin-3- O-β-D-glucoside ( 4 ) , kaempferol-3-rutinoside ( 5 ) ,
rutin (6) , 2″- O-galloylrutin (7 ) , bergenin ( 8 ) , gallic acid ( 9) and methyl gallate ( 10) . Six compounds were found from the plant for the first time with the exception of 2 , 6 , 8 and 10 . These results provided new chemical evidences for the bioactive investigation of this plant .
