目的优选小儿解感颗粒制备药材中黄芩苷的提取工艺。方法采用正交试验法考察加水量、提取时间、提取次数3个因素,HPLC法测定黄芩苷的含量,以黄芩苷得率为指标,确定黄芩苷的最佳提取工艺。结果提取次数对黄芩苷的提取效率影响显著。最佳提取工艺为加水6倍量提取2次,第1次3 h,第2次2 h。结论该方法操作简便、有效,为小儿解感颗粒中黄芩苷的提取方法提供参考依据.
Objective To optimize the extraction process of baicalin in the preparation of herbal medicine for children. Methods Orthogonal test was used to study the factors such as the amount of water, extraction time and extraction times. The content of baicalin was determined by HPLC, and the best extraction technology of baicalin was determined by the yield of baicalin. The results of extraction times on the extraction efficiency of baicalin significant effect. The best extraction process was 6 times the amount of water extraction 2 times, the first 3 h, the second 2 h. Conclusion The method is simple and effective, and provides a reference for the extraction of baicalin in children Jieyang granules.
