摘要:

采用三因素二次回归正交旋转组合设计方法,研究液固比、浸提温度、浸提时间对黄芩多糖提取率的影响,确定黄芩多糖的较优提取工艺。结果表明:通过频率分析法得到黄芩多糖最优提取工艺为液固比30:1(ml/g)、浸提温度85℃、浸提时间100min,在此工艺条件下黄芩多糖提取率为4.92%。

Abstract:

Three factors quadratic orthogonal rotation design was used to investigated the factors influencing the yields of the polysaccharides of Scutellaria baicalensis Georgi like liquor/solid ratio, extraction temperature, and extraction time. The optimum extraction conditions were as follows: liquor-solid ratio of 30:1, extraction temperature of 85 ℃ and 100 min of extraction time. The yield of the polysaccharides of Scutellaria baicalensis Georgi was 4.92% under above conditions.

Key words: quadratic regression rotation-orthogonal combination design, polysaccharides from Scutellaria baicalensis Georgi, rate of extraction, optimization
