| 摘 要： | 目的优选淫羊藿的提取工艺.方法以淫羊藿苷的含量为指标,应用正交试验设计筛选淫羊藿的最佳提取工艺条件.结果影响提取的主次因素为B＞A＞E＞D＞C(A为药材粉碎度;B为乙醇浓度;C为乙醇用量;D为回流时间;E为回流次数).最佳提取条件为药材粗粉,75%乙醇,加25倍量,回流60min,回流7次.根据优选工艺验证实验表明,有效成分提取率较高,重现性较好.结论优选得到的工艺稳定可行.

| Abstract: | Objective: To optimize the extraction pr ocess of Herba Epimedii . Methods: The optimum extracti on conditions were investigated by orthogonal design and with Icariin as the c ontent index. Results: The factors influencing extraction efficiency were as follows: B>A>E>D>C (A:Particle size. B:The concentration of ethanol. C:The amount of added ethanol. D:Duration of reflux. E:Times of refl ux). The optimum extraction condition obtained was: coarse powder, 75 percent et hanol, the refluxing and extracting for 7 times, 60 min for every turn, 25 folds of ethanol. The content of Icariin was fairly high with a good reproducibility. Conclusion: The optimized process is stable and high effic ient. |
