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
