摘要
应用挤出滚圆法制备盐肤木总酚酸微丸,优化处方组成及其制备工艺。以收率、外观以及成丸性能为评价指标对处方因素(载药量、稀释剂、润湿剂和抗黏剂)进行单因素考察,优选处方组成;采用Box-Behnken设计与响应面法,以挤出速度、滚圆速度、滚圆时间为自变量,收率、脆碎度和圆整度的总评归一化值为因变量,优化制备工艺。单因素试验确定的最佳处方组成:载药量为28. 7%,微晶纤维素-乳糖9∶1,二氧化硅为抗黏剂,60%乙醇为润湿剂; Box-Behnken试验优化的制备工艺参数:挤出速度43 r·min-1,滚圆速度1 800 r·min-1,滚圆时间4 min,在此条件下,预测值和测定值偏差绝对值<5. 0%,与模型拟合程度较高,得到的制备工艺参数准确可靠,重复性良好。在扫描电镜下观察该工艺制备的盐肤木总酚酸微丸,粒径较均一,表面圆整光滑。该研究优化筛选出的处方组成及制备工艺稳定可行,可用于盐肤木总酚酸微丸的制备。
Extrusion-spheronisation method was used to prepare Rhus chinensis total phenolic acid pellets. The formula and preparation of R. chinensis total phenolic acid pellets were optimized. The formulas( drug loading capacity,diluent,wetting agent and anti-sticking agent) were determined by the single factor test with yield,appearance and performance as the indexes. The preparation was optimized by Box-Behnken design and response surface method,with the rate of extrusion,rate of spheronization and time of spheronization as the independent variables and the overall desirability value of yield,friability and roundness as the dependent variables. The optimal formula of pellets was as follows: drug loading capacity 28. 7%,MCC-lactose 9 ∶1,silicon dioxide as anti-sticking agent,and 60% ethanol as wetting agent. The optimal preparation was determined as follows: the rate of extrusion was 43 r·min-1,the rate of spheronization was 1 800 r·min-1,and the time of spheronization was 4 min. The absolute deviation between predicted value and estimated value under the conditions was less than 5. 0%,with a high degree of model fit. The preparation parameters obtained were accurate,reliable and reproducible. Under scanning electron microscopy( SEM),R. chinensis total phenolic acid pellets were uniform in diameter,round and smooth. The optimal formulation and process are stable and feasible for preparing R. chinensis total phenolic acid pellets.
