目的:研究导痰祛瘀口服液的提取工艺。方法:采用 Ｌ９(３４)正交试验设计及Ｕ４７均匀试验设计,以大黄中的大黄素含量及石菖蒲中挥发油含量分别为指标进行试验。结果:较好渗漉条件为 ５５%乙醇渗漉１０倍量,５%ＮａＯＨ作润湿液,流速为３ｍｌ/ｍｉｎ;较好蒸馏条件为药材粉碎成粗粉,加水１６倍,蒸馏５ｈ。结论:研究所得工艺较合理。 Objective: To study the extraction process of Guiqi Oral Liquid. Methods: L9(34) orthogonal test design and U47 uniform test design were used to test the content of emodin in rhubarb and volatile oil content in I. glabra. Results: The better osmotic conditions were 55% ethanol percolation 10 times, 5% NaOH as the wetting fluid, and the flow rate was 3ml/min. The better distillation conditions were that the medicinal material was crushed into coarse powder, water was added 16 times and distilled for 5 hours. Conclusion: The research process is reasonable.
