Preparation and Quality Evaluation of Proanthocyanidin B2 Phospholipid Complexes
objective:To optimize the preparation process of PB2-PC and to characterize it.Methods:A one-way test was used to determine the optimal preparation process for PB2-PC and to characterise it.RESULTS:The optimal preparation process was:tetrahydrofuran as solvent,phospholipid to PB2 ratio of 2.PB2 concentration was 5 mg·mL-1,and the reaction was carried out at 40℃for 0.5 h.The worthwhile complexes log P enhancement,transformation to amorphous form and change in physical phase.conclusion:PB2 preparation process is stable and reliable.
