摘要: | 目的:优选复方翻白草颗粒剂药材的提取工艺和颗粒成形的辅料。方法:以山柰酚、槲皮素、总黄酮含量组成的综合评分为指标,以加水量、浸泡时间、煎煮时间、煎煮次数为考察因素,采用单因素试验和正交试验优化处方药材提取工艺并进行验证试验;以颗粒的成形率、溶化率、吸湿率、休止角组成的综合评分为指标,采用单因素试验优选颗粒成形中的辅料类型及配比。结果:最优提取工艺为药材加14倍量水浸泡0.5 h,煎煮3次,每次1.0 h;验证试验显示山柰酚、槲皮素、总黄酮含量的RSD分别为1.77%、1.76%、4.62%(n=5);成形工艺中的辅料选择糊精与可溶性淀粉(2 ∶ 1)的混合物,所制颗粒成形率、溶化率、吸湿率、休止角分别为94.02%、76%、26%、25.02 °。结论:优选的复方翻白草颗粒剂药材提取工艺稳定、可行,所制颗粒成形性和抗湿性较好。 |
ABSTRACT: | OBJECTIVE: To optimize the extraction technology and forming technology of Compound Potentilla discolor granules. METHODS: The extraction technology was optimized by single factor and orthogonal test with the amount of added water, soaking time, decocting time and decocting times as factors using the comprehensive score of the content of kaempferol, quercetin, and total flavonoids as indexes. Validation test was conducted. The type and ratio of excipients in forming technology were optimized by single factor test using comprehensive score of molding rate, soluble rate, moisture absorption rate and angle of repose as indexes. RESULTS: The optimal extraction process was 14-fold water, soaking for 0.5 h, decocting for 3 times, 1.0 h each time. The RSDs of kaempferol, quercetin and total flavonoids content in validation test were 1.77%, 1.76% and 4.62% (n=5). The excipients of forming technology was the mixture of dextrin and soluble starch (2 ∶ 1); the molding rate, soluble rate, moisture absorption rate and angle of repose were 94.02%, 76%, 26% and 25.02 °, respectively. CONCLUSIONS: The optimized extraction technology of Compound P. discolor granules is stable and feasible, and prepared granules have good formability and moisture resistance. |
