| 摘 要： | 对用超声波法从葡萄穗轴废渣中提取白藜芦醇的工艺进行了研究。用薄层层析法分离后，用紫外分光光度计测定吸光度，得出白藜芦醇的提取率。考察了不同提取时间、温度、占空比、固液比对白藜芦醇提取率的影响，通过单因素实验和正交实验确定了最佳提取条件：提取剂为体积分数60%的乙醇，超声作用时间为6 min，占空比1∶2，提取温度为70 ℃，固液比为m(葡萄穗轴废渣质量):m(乙醇溶液质量)＝1∶13，白藜芦醇一次提取率达0.33%。

| Abstract: | The ultrasonic extraction of resveratrol from grape spike-stalk waste residue was studied by separation with thin layer chromatography，The yield of resveratrol was determined by ultraviolet spectrometry. The effect of various factors such as extraction time，extraction temperature，duty ratio and solid/liquid ratio on the extraction yield of resveratrol was investigated. On the basis of single factor and orthogonal experiment，the optimum conditions were determined as follows：volume fraction 60% ethanol solution as extractive solvent，extraction time 6 min，extraction temperature 70℃，solid/liquid ratio 1∶15，the extraction yield of resveratrol could reach 0.33%. |
