中文摘要：

本文研究了葡萄果实中白藜芦醇提取的最优工艺以及在最优提取条件下葡萄不同品种、果实不同部位白藜芦醇的含量差异。结果表明,葡萄果实中白藜芦醇提取的最优条件为乙醇浓度50%、水浴温度60℃、水浴时间40 min、超声时间6 min和料液比1∶6。在最优提取条件下,白藜芦醇含量因品种和部位的不同而有差异。同一品种葡萄果实中不同部位白藜芦醇含量由高到低依次为果皮〉果肉〉果籽。供试4个品种葡萄中白藜芦醇含量由高到低依次为巨峰葡萄〉马奶葡萄〉国产红提〉进口红提。

英文摘要：

The optimum extraction process of resveratrol in grape and the resveratrol content under optimum technological conditions of different parts of different grape varieties were studied.The results showed that the optimal conditions of resveratrol in grape fruit were extracted of 50% ethanol concentration,water bath temperature of 60 ℃,water bath time of 40 min,ultrasonic time of 6 min and liquid ratio of 1 ∶6.Under the condition of the optimal extraction,resveratrol content with different varieties and parts had difference.The content of resveratrol in different parts of the same variety of grape fruit was peel〉 fruit〉 fruit seed. The content of resveratrol in different varieties of grape fruit was kyoho grape 〉mares grape 〉domestic red grape〉import red grape.
