摘　　要：研究分析荞麦萌发过程中芦丁和槲皮素含量的变化趋势,为荞麦萌动食品的开发提供了理论参考。以发芽时间为试验因素,采用反相液相色谱法对荞麦萌发前后的芦丁和槲皮素进行测定比较。结果表明(1)萌发有助于提高苦荞中芦丁和槲皮素的含量,有助于提高甜荞中芦丁的含量。苦荞萌发7 d后芦丁含量为19.33 mg/g远高于甜荞的0.66 mg/g。(2)苦荞萌发过程中芦丁含量呈先上升后下降再上升的趋势,萌发7 d后芦丁含量提高了66.64%。甜荞萌发7 d后,芦丁含量提高了75.13%。苦荞萌发7 d,槲皮素含量整体呈上升趋势,由8.93 mg/g上升至11.90 mg/g。甜荞萌发过程中未检测出槲皮素。荞麦萌动后提高了黄酮类成分,苦荞中的芦丁含量萌发前后均高于甜荞,选择苦荞作为荞麦萌动食品原料具有更好的营养价值。Content changes trend for rutin and quercetin in germinating buckwheat seeds was studied. In order to provide references for the development of buckwheat germinated food. The germination time as experiment factors, using reversed-phase liquid phase chromatography of buckwheat germination and rutin and quercetin were measured and compared. The results showed that （1） the germination to help to improve the content of rutin and quercetin in F.tartaricum Guerth, was helpful to improve the content of Rutin in F.esculentum Moench. F.tartaricum Guerth, germinated after 7 d rutin content was 19.33 mg/g higher than F.esculentum Moench 0.66 mg/g. （2） F.tartaricum Guerth germination rutin content was increased at first and then decreased and increase trend, after 7 d of germination of the content of rutin improved 66.64 %. F.esculentum Moench germinated after 7d, rutin content increased by 75.13 %. F.tartaricum Guerth, germination of 7 d, the content of quercetin in the overall upward trend, increased from 8.93 mg/g to 11.90 mg/g. F.esculentum Moench germina- tion process of quercetin was not detected. The flavonoids components were increased after F.tartaricum Guerth germination.Content of rutin of F.tartaricum Guerth was higher than F.esculentum Moench in germination. Selecting F.tartaricum Guerth as raw material of germinated food may have better nutritional value.
