【摘要】 对显齿蛇葡萄中二氢杨梅素的超声辅助溶剂提取工艺进行了研究,在单因素实验和正交实验的基础上,得出超声波法辅助溶剂提取显齿蛇葡萄中二氢杨梅素的最佳工艺条件为:在40℃下,以液料体积质量比为15 mL∶1 g的体积分数65%乙醇溶液,超声波辅助溶剂提取40 min,目标物二氢杨梅素的一次提取率可达93.1%,优于常规的热提取法。更多还原

【Abstract】 In this manuscript,the solvent extraction of dihydromyricetin assisted by ultrasonic wave was studied.The optimum process parameters based on the single factor and orthogonal test as follows:the temperature 40 ℃,the ratio of solution to solid 15∶1,the concentration of ethanol was 65% and the operating time of ultrasonic wave 40 min,the extraction rate could reach at 93.1%.The ultraonic-assistent extraction method was superior over the other traditional ethanol method.更多还原
