【摘要】 以汉中银杏树叶为原料,采用有机溶剂提取法对银杏叶中黄酮类化合物的提取工艺进行研究,通过单因素实验研究了不同提取温度,提取液浓度,提取次数,超声波对银杏叶中黄酮提取率的影响,其中对其显著地影响因素采用正交试验作以继续探究,得到:在提取温度70℃,提取液浓度为70%,提取次数为3次下为最佳提取条件,并且对黄酮类物质作以性能研究得到:黄酮类物质对绿豆幼苗有壮苗作用。更多还原

【Abstract】 The extiaction technology of flavonoids in Ginkgo leaves of Hanzhong area by the method of organic solvent extra was studied,with ginkgo leaves as the raw material.The effect of the different extraction temperature,extraction concentration,extraction times,ultrasound waves of Ginkgo leaf flavonoid,one of the significant factors affecting the orthogonal experiment to continue was explored.The conditions were the extraction temperature 70 ℃,extraction concentration 70%,extraction times was 3 times as the best extraction condition,and performance of flavonoids played an important role of bean seedlings.更多还原
