目的 优化养心安神颗粒提取工艺.方法 以挥发油得率为指标,采用单因素试验考察加水量、浸泡时间、提取时间对挥发油得率的影响;以加水量、提取时间、提取次数为考察因素,以提取液中芍药苷和总固形物含量为综合评价指标,采用正交试验设计优化养心安神颗粒的提取工艺.结果 最佳提取工艺为:桂枝、防风、佛手加8倍量水,蒸馏6 h提取挥发油;其余药味加8倍量水煎煮1 h,提取2次.结论 该提取工艺合理可行,并能较好保证制剂质量.%Objective To optimize the extraction technology for Yangxin Anshen Granules. Methods With yield of volatile oil as index, single factor tests were adopted to investigate effects of water, soaking time and distillation time on extraction technology of volatile oil. Using water amount, extraction time and extraction times as factors, the contents of paeoniflorin and total solid as indexes, orthogonal test was employed to optimize the extraction technology of Yangxin Anshen Granules. Results The optimical extraction technology conditions were as follows:Cinnamomi Ramulus, Saposhkoviae Radix, and Citri Sarcodactylis Fructus were extracted to get volatile oil with eight-folds amount water of herbs for 6 hours; other herbs were boiled with eight-folds amount water of herbs and extrancted for two times, 1 h each time. Conclusion This extraction process is reasonable and practical, and can well guarantee the quality of preparation.
