| Abstract: | Objective To standardize the kaempferol reference substance.Methods HPLC-diode array detection(DAD)was applied to determine the purity of kaempferol,and then the purity of kaempferol were calculated both by area normalization method and self-contrasted dilution method.Results The results of normalization method and self-contrasted dilution method showed that the purity was over 98.0 %.Conclusion Purity of this batch of kaempferol could reach the requirement of chemical reference standards for traditional Ch... |
