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。
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.
