Abstract:After germination，the tartary buckwheat was divided into two parts：malt and kernel.The contents changes of total flavonoids，rutin，quercetin and D-CI of malt powder and whole powder was studied in the different germination.The results showed that the content of total flavonoids，rutin and D-CI decreased gradually and the content of quercetin increased slowly from second day of germination later in the malt powder.The D-CI content of malt powder was as high as 18.38 mg/g in the second day of germination，however the D-CI content was only 0.32 mg/g of whole buckwheat powder without germination.With the germination，the content of total flavonoids and rutin of the whole powder increasd firstly and then decreased.The content of total flavonoids reached the maximum at 27.92 mg/g on the seventh day of germination，and the content of rutin reached the maxmum at 23.13 mg/g on the sixth day of germination.The content of quercetin of whole powder increased with germination.The quercetin content increased rapidly in the mid-anaphasc germination，and the content was 6.85 mg/g on the eighth of germination.The D-CI content was increasing slowly that the content was 1.07 mg/g on the first day and 1.51 mg/g on the sixth day of germination.The content of total flavonoid，rutin，D-CI of malt powder was higher in the early germination.The synthesis of D-CI of whole powder was also occurred in the early germination；and the synthesis of rutin and quercetin was mainly occurred in the mid-anaphasc germination.
