OBJECTIVE
Optimize the technic condition of Duzhong Jiangya prescription with Semi-bionic Extraction.
METHOD
Using homogeneous design, under the same materials granularity, decoction temperature, consumption of water, filtration, concentration, and taking aucubin, hydrochloric acid stachydrine, maloicacid, baicalin, ethanol extract, dry extract as the indexes, the results were comprehensive considered to optimize the semi-bionic extraction condtions.
RESULT
The optimized SBE extraction conditions are the following: pH values of the water for the thrice extraction is 5.845 3, 7.496 1, 8.011 7, and the total extraction time is 3.418 0 h.
CONCLUSION
Considering the fact of manufacture, the SBE extraction conditions are the following: pH values of the water for the thrice extraction is 6.0, 7.5, 8.0, and the thrice extraction time is 1.5, 1.0, 1.0 h.
目的
优化杜仲降压方的半仿生提取工艺条件。
方法
采用均匀设计法，在物料粒度、煎煮温度、加水量、过滤、浓缩相同的条件下，以桃叶珊瑚苷、盐酸水苏碱、苹果酸、黄芩苷、乙醇提取物、干浸膏为指标，综合考虑结果优化半仿生提取条件。
结果
优化后的半仿生提取条件为：三次提取用水的pH值分别为5.845 3、7.496 1、8.011 7，总提取时间为3.418 0小时。
结论
考虑到生产实际情况，半仿生提取条件为：三次提取用水的pH值分别为6.0、7.5、8.0，三次提取时间分别为1.5、1.0、1.0小时。
