Objective:To study on solubilization of dihydromyricetin(DMY) by hydroxpropyl-β-cyclodextrin(HP-β-CD).Method:Inclusion of HP-β-CD on DMY under different temperatures was investigated by phase-solubility method.The content of DMY was determined by HPLC.Result:With increasing of HP-β-CD in aqueous solution
solubility of DMY increased linearly
which showed typical AL-type phase solubility diagram.The molar ratio of DMY and HP-β-CD in the inclusion complex was 1∶ 1.The apparent stability constants of inclusion reaction at 25
35
45 ℃ were determined as 500.0
944.8
2 449.8 mol · L-1
respectively.Conclusion:The solubility of DMY was improved remarkably by HP-β-CD inclusion.
