苦荞发芽后,将其分为芽及去除芽后的籽粒两部分,在发芽期间,对芽和籽粒中的总黄酮、芦丁、槲皮素及D-CI含量变化进行研究.发芽第二天开始,随着发芽时间延长,芽粉中总黄酮、芦丁、D-CI含量呈下降趋势,槲皮素含量缓慢上升;发芽第二天,芽粉中D-CI含量高达18.38 mg/g,未萌动的苦荞全粉中D-CI含量为0.32 mg/g.随发芽时间延长,全粉中总黄酮、芦丁含量呈先上升后下降趋势,在发芽萌动第七天总黄酮含量达到最大值,为27.92 mg/g,第六天芦丁含量达到最大,为23.13 mg/g;槲皮素含量变化呈上升趋势,在发芽中后期含量上升迅速,发芽第八天其含量为6.85 mg/g;D-CI含量变化呈缓慢上升趋势,第一天其含量为1.07 mg/g,第六天其含量为1.51 mg/g.芽粉中总黄酮、芦丁、D-CI在发芽初期含量较高;全粉中D-CI的合成也主要发生在发芽初期,芦丁、槲皮素的合成主要在发芽中后期.%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 dif-ferent 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 ear-ly germination;and the synthesis of rutin and quercetin was mainly occurred in the mid-anaphasc germination.
