| Abstract: | To discuss a fast determination of Bergenin in the Rodgersia aesculifolia Batal.by using Bergenin as standard sample and UV spectrophotometry.Using alcohol as solvent at 275nm the calibration curve is good linear over 0.04-0.8mg/ml(r=0.998) and the mean recoveries are 100.02%.The method is simple,fast,accurate and reliable,and it is proper for fast analysis. |
