摘要
目的:通过改变煎煮时间,研究黄芩苷的提取工艺,从而确定最佳条件。方法:选用单因素水平法,考察提取时间对黄芩苷收率的影响。利用HPLC法测定黄芩提取物中黄芩苷的含量。结果:黄芩在提取2次,提取时间均为60min的条件下,黄芩的出膏率和黄芩苷的含量最高。结论:水提方法合理,收率高,成本低,适用于黄芩苷的提取。
Objective： To study the water extraction techniques of Radix Scutellariae. Methods ： Selection of single factor levels, inspection from to baicalin yield impact. The Use the HPLC to determination, the content of baicalin yield. Results： The soaking time significantly effect the extracting efficiency. Conclusion：The optimal decocting conditions of the root of Scutellaria baicalensis Georgi were refluxing for two times, adding 10 times a- mount of water for the first time and 8 times for the second time, no soaking, and 1 hours for the first time and 1 hour for the last one.
