正交试验优选芪句颗粒水提取工艺

Optimization of Water Extraction Technology for Qiju Granule by Orthogonal Test

目的:优选芪句颗粒的提取工艺。方法:以黄芪甲苷含量和出膏率为评价指标,采用L9(34)正交设计优选芪句颗粒提取工艺。结果:最佳水提取工艺为加18倍量水提取2次,每次1 h。结论:该优选工艺合理可行。

Objective： To optimize extraction process of Qiju granule. Method： With the content of astragaloside IV and extract rate as indexes, extraction process was optimized by L9 （34） orthogonal method. Result： Optimum extraction technology of Qiju granule was as follows： extracted 2 times with 18 times the amount of water, 1 h each time. Conclusion： This optimized extraction process was reasonable and feasible.
