摘要 采用逆相蒸发法制备茶多酚脂质体并进行质量评价。通过二次回归旋转组合设计优化茶多酚脂质体制备工艺及配方,对其形态、结构、粒径分布等性质进行考察。研究结果表明,最佳配方为m(大豆卵磷脂)∶m(胆固醇)=3∶1、茶多酚质量浓度为7 mg/mL、V(有机相)∶V(水相)=4∶1、磷酸盐缓冲液浓度15 mmoL/L,此条件下包封率为50.37%;所制备的茶多酚脂质体形态呈圆球形或椭球形,为大单室脂质体,有效粒径为165.3 nm,Zeta电位为-69.3mV。逆相蒸发法制备茶多酚脂质体方法简单可行,所制备的脂质体具有一定缓释性。 Tea polyphenol liposomes were prepared by reverse-phase evaporation. The quadratic rotationregression-orthogonal combination was designed to optimize the technique parameters,and the indices including the character, structure and particle distribution of tea polyphenols liposomes were investigated. The optimal conditions were as follows: ratio of soybean phospholipids to cholesterol was 3:1 (m/m) ,the concentration of tea polyphenols was 7 mg/mL, the ratio of oil phase to aqueous phase was 4:1 (V/V) ,the concentration of phosphate buffer saline was 15 mmol/L. The encapsulation efficiency was up to 50.37%. The shape of the lipsomes was spherical or ellipsoidal and the structure of the lipsomes was large unilamellar vesicles. The effective diameter was 165.3 nm,and the zeta potential was -69. 3 inV. The preparation of reverse-phase evaporation was simple and feasible. The prepared lipsomes had releasing function of tea polyphenols.
