摘要
采用酶法提取工艺提取银杏叶中总黄酮,与传统水浸提工艺相比,提取率提高了25.1％。本工艺提取率高,提取条件温和。实验确定的提取工艺条件为:提取温度50℃,提取pH4.5,提取时间90min,酶与银杏叶配料比1:140。
Using enzyme, a new technology of extracting total flavone from ginkgo biloba leaves is developed. Compared with traditional extracting technology by water, the extracting ratio of total flavone is increased by 25.1 % . Vsing this enzyme - based extracting technology. The enzyme - based extracting technology is characterized by its high extracting ratio and gentle extracting conditions determined experimentally are as following: extracting temperature is 50 t, pH of extracting media is 4.5, the extracting time is 90 min and the weight radio of enzyme to ginkgo biloba leaves is 140:1.
