摘要(Abstract):

制备并优化共载细叶远志皂苷和β-细辛醚自微乳(TF/ASA-SMEDDS),并进行质量评价。通过溶解度试验、单因素试验及伪三元相图的绘制,筛选TF/ASA-SMEDDS的处方组成;采用Box-Behnken效应面法,以载药量和粒径为考察指标筛选最优处方,并进行乳化外观、粒径、形态以及体外释放的考察。最终确定TF/ASA-SMEDDS的最优处方为辛酸癸酸三甘油酯-聚氧乙烯蓖麻油-丙三醇(10.8∶39.2∶50),其中细叶远志皂苷载药量为(5.563±0.065)mg·g~(-1),β-细辛醚的载药量为(5.526±0.022)mg·g~(-1),乳化后可形成均一透明泛蓝光的纳米乳,粒径为(28.84±0.44)nm;TEM显示TF/ASA-SMEDDS乳化后可形成粒径均一的圆球状结构;体外溶出试验结果显示细叶远志皂苷和β-细辛醚溶出速率及释放度均显著提高。TF/ASA-SMEDDS制备工艺简单,可有效提高细叶远志皂苷和β-细辛醚的释放度。
To prepare and optimize the self-microemulsion co-loaded with tenuifolin and β-asarone(TF/ASA-SMEDDS) and evaluate its quality. The prescription compositions of TF/ASA-SMEDDS were screened by solubility test, single factor test and pseudo-tern-ary phase diagram, and the prescriptions were further optimized by Box-Behnken response surface method, with the drug loading and particle size as the evaluation indexes. Then the optimized TF/ASA-SMEDDS was evaluated for emulsified appearance, particle size, morphology and drug release in vitro. The optimized prescription for TF/ASA-SMEDDS was as follows: caprylic citrate triglyceride polyoxyethylene castor oil-glycerol(10.8∶39.2∶50), drug loading of(5.563±0.065) mg·g~(-1) for tenuifolin and(5.526±0.022) mg·g~(-1) for β-asarone; uniform and transparent pan-blue nanoemulsion can be formed after emulsification, with particle size of(28.84±0.44) nm. TEM showed that TF/ASA-SMEDDS can form spherical droplets with a uniform particle size after emulsification; In vitro release test results showed that the drug release rate and cumulative release of tenuifolin and β-asarone were significantly improved. The preparation process of TF/ASA-SMEDDS was simple and can effectively improve in vitro release of tenuifolin and β-asarone.
