Optimization of Extraction Technology for Yangxin Anshen Granules with Orthogonal Test / 中国中医药信息杂志

ABSTRACT

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.
