Abstract: Objective To determine the content of hyperoside and oleanolic acid in Diospyros kaki.Methods The HPLC method was used to determine the content of hyperoside and oleanolic acid in Diospyros kaki.The analysis of hyperoside was carried out on Shi madzu C18column (150mm×4.6mm,5μm).The mobile phase was MeOH-0.2%H3PO4(45:55).The flow-rate was 1.0mL/min.The detection wave-length was 350nm.The analysis of oleanolic acid was carried out on ShimadzuC18column(150mm×4.6mm,5μm).The mobile phase was MeOH-0.2% H3PO4(90:10).The flow -rate was 0.8 mL/min.The detection wave -length was 220nm.Results The liner range of hyperoside was 0.50-2.50μg and gave a correlation (r) of 0.9999.The recovery was 99.65% and RSD was 1.24 % .The liner range of oleanolic acid was1.56-5.20μg and gave a correlation (r) of 0.9990.The recovery was 97.02% and RSD was 2.84 % .Conclusion The method is simple, fast and had a good linear relationship.It is to determine the content of hyperoside and oleanolic acid in Diospyros kaki.
