摘　　要：本文对苦荞麸皮中黄酮的喷淋提取工艺进行研究。以总黄酮得率为检测指标,通过均匀设计试验,分别探讨了以水和乙醇两种溶剂的喷淋工艺中料液比和提取时间两个因素对苦荞麸皮中黄酮得率的影响,得到水和乙醇两种溶剂的喷淋工艺,且将优化工艺的得率和提取物的芦丁及槲皮素含量与以甲醇和乙醇为溶剂的传统浸提方法相比较。This paper studied the spray extraction process of flavonoids from tartary buckwheat bran.Taking the yield of total flavonoids as the detection index,the effects of two factors,the ratio of solid to liquid and the extraction time in the spraying process of water and ethanol,on the yield of flavonoids in tartary buckwheat bran were investigated through uniform design experiments.The spray process of two solvents,water and ethanol,was obtained,and the yield of the optimized process and the content of rutin and quercetin in the extract were compared with the traditional extraction method using methanol and ethanol as solvents.
