    摘要:

    以合成磷脂DPPC和氢化大豆卵磷脂HSPC为膜材,采用薄膜超声法和乙醇注入法制备β-紫罗兰酮脂质体,并对其超声条件及配方进行优化。优化得到的较佳工艺参数为:超声功率240 W,超声时间4 min。通过单因素实验优化得到的β-紫罗兰酮脂质体的较佳配方为:DPPC与HSPC摩尔比为8∶2,磷脂质量浓度10 mg/mL,β-紫罗兰酮与Tween80、磷脂的质量比为1∶1∶20。该条件下制备的脂质体包封率为(60.62±3.48) %,平均粒径在200 nm左右,在原子力显微镜的观察下为球状或近似球状的小囊泡。

    Abstract:

    To prepare beta-ionone liposomes bythin-film evaporation and ethanol injection using DPPC(1,2-dipalmitoyl-sn-glycero-3-phosphocholine) and HSPC(hydrogenated soy phosphatidy- lcholine) as membrane materials,as well as optimize its preparation formula.The results showed that the optimal preparation condition and formula of beta-ionone liposomes was as follows:the molar ratio of DPPC to HSPCwas 8∶2,the concentration of phosphatidylcholine(PC)was 10 mg/mL,the mass ratio of beta ionone toPCs was 1∶20,the ratio of Tween80 to PCs was 1∶20,the ultrasonic power was 240 W,the time was 4 min.Under these conditions,entrapment efficiency of beta-ionone liposomes was 60.62%±3.48%. The diameters of beta-ionone liposomes were about 200nm,the appearances ofbeta-ionone liposomes were completely or approximately globular vesicles under atomic force microscope(AFM).
