香柏总黄酮的提取工艺优化

目的：优化香柏总黄酮的超声波提取工艺。方法：采用单因素及正交试验法确定香柏总黄酮的最佳提取工艺条件。结果：超声波提取香柏总黄酮的最佳工艺条件为在功率250W 超声波功率条件下，提取时间70min、乙醇体积分数75%、液固比10:1(mL/g)、提取次数2 次，此条件下的总黄酮提取率为5.29%。结论：该方法操作简单、方便适用，可以用于工业化生产。

Process Optimization for Extraction of Total Flavones from Sabina pingii var.wilsonii

The key conditions for extracting total flavones from the branches and leaves of Sabina pingii var.wilsonii with aqueous ethanol solution under the assistance of ultrasound,including ultrasound treatment time,ethanol concentration,liquid/solid ratio,and extraction times,were optimized by combined single factor and orthogonal array design methods.The optimal conditions for improved extraction of total flavones were determined as follows:70 min ultrasound treatment repeated twice for extracting the raw materi...
