摘　　要：以火炬树芽为原料,在单因素试验的基础上,采用响应面分析法确定其多糖的最佳提取工艺。结果表明,火炬树芽多糖提取的最佳工艺参数为液料比24∶1(mL/g)、提取时间2 h、提取温度66℃、超声时间50 min。验证优化工艺参数得到多糖得率为3.59%,与模型预测得率3.67%基本吻合,由红外光谱分析表明所得提取物为多糖类物质。Based on the single factor experiment,the sprout of Rhus typhina was used as the raw material to determine the optimal extraction condition of polysaccharides by response surface analysis.Results showed that the optimal extraction condition was liquid-to-solid ratio 24∶1(mL/g),extraction time 2 h,extraction temperature 66℃,ultrasound time 50 min.Verify optimization of extraction parameters,the polysaccharides yield was 3.59%,was consistent with the predicted yield 3.67%basically,the infrared spectroscopy analysis showed that the extraction was polysaccharide compound.
