| Abstract: | In this paper,flavonids were extracted from plumula nelumbinis using the method of alkali dissolution and acid separation.Flavonids were identified through the method of reaction with magnesium-hydrochlorie acid and IR characterization.In addition,all the flavonids in leaves and culms of plumula nelumbinis were determined by spectrophotometry with rutin as the standard,and the results were 4.135 mg/g and 6.266 mg/g,respectively.Effects of time and pigment on the determination were investigated,and the resul... |
