湖南香柚皮中黄酮类物质提取工艺的研究

The Research of the Extraction of Flavonoids from Hunan Grapefruit Peel

以湖南香柚皮为原料,采用溶剂法和超声波辅助法对柚皮中黄酮类物质的提取工艺进行研究,其最佳提取工艺为:固液比1∶25(g/mL),乙醇体积分数80%,超声波提取时间60min,溶液pH值7.0,黄酮类物质的提取率达2.42%。

This paper reviewed the research of the extraction of flavonoids from Hunan grapefruit peel. The better technical condition is the 1 ： 25 （g/mL） of solid-to-liquid ratio, the 80% of alcohol concentration, the 60 rain of sonication, the 7 of pH value. Under the condition, it can get the 2.42 extraction percentage of flavonoids.
