摘要
对银杏叶提取物的提取和精制工艺进行了研究 ,确定了提取溶剂、时间、次数及浓缩、干燥温度等提取工艺参数。比较了树脂吸附一次洗脱和二次洗脱以及超滤与树脂吸附相结合的精制工艺对产品质量及总黄酮收率的影响。结果表明 。
The Ginkgo biloba Leaves extracts was prepared using reflux extraction method and ultrafiltration combined with absorption resin chromatography as purification method. Extraction conditions such as extraction reagents, the ratio of liquid to solid, extraction times, the condensing and drying temperature and extract time were optimized, and the extractive ration of total flavonoids was about 78% in the optimal condition. The purification process was effective, the content of total flavonoids was above 24%.
