蜘蛛香总缬草三酯固体自微乳的制备及体外评价
Journal of Chinese Medicinal Materials(2019)
Abstract
目的:制备蜘蛛香总缬草三酯固体自微乳,并对其进行体外评价.方法:测定不同吸附材料的吸附量、释放度、休止角、流出速度、豪斯纳比、颗粒间孔隙率、卡尔指数,运用主成分分析法筛选蜘蛛香总缬草三酯固体自微乳的最佳处方,并考察其理化性质.结果:蜘蛛香总缬草三酯固体自微乳最佳处方为:蜘蛛香总缬草三酯自微乳-β-环糊精(1∶5.714,g/g),载药量21.722±0.237 mg/g,分散后乳剂粒径46.2±0.75 nm、Zeta电位-6.17±0.15 mV,15min累积溶出度93.900%,光照会影响该制剂的稳定性,应避光保存.结论:蜘蛛香总缬草三酯固体自微乳粉体学性质较好,制备工艺简单易行,具有良好的应用前景.
