Abstract: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.tartaricumGuerth，germinatedafter7drutincontentwas19.33mg/g higher than F.esculentum Moench 0.66mg/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 germination 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.
