【摘要】 本文对芹菜中黄酮类物质的提取进行了研究,研究结果表明,乙醇溶液对黄酮类物质的提取效果好于碳酸钠溶液和水;鲜芹菜榨汁与浸提结合的效果优于只榨汁或只浸提。采取正交实验的方法得出:70%乙醇溶液,60℃提取温度,提取时间90min,可得最高提取率761mg/100g干芹菜叶。更多还原

【Abstract】 In this paper, the extraction of flavonoids from celery was investigated. The results showed that the extracting efficiency of ethanol solution is better than those of sodium carbonate solution and water. Moreover, juicing and leaching of the fresh celery must be combined with each other as the best process. By adopting the cross experiment, the maximum extraction rates of 761mg/100g was achieved with the ethanol solution being 70%, temperature being 60℃ and the extracting time being 90 min.更多还原
