摘要: 荞麦花中的黄酮含量最高,平均含量达7.4%,开花后逐渐下降;其次是叶,黄酮的平均含量为5.3%,并在开花期达到最高峰,后期下降;茎中的含量较低,平均值为1.0%,生育期中无明显变化。籽粒中,以苦荞的黄酮含量高,平均值为2.02%,甜荞的黄酮含量平均值仅为0.23%。放射线对荞麦进行辐射可使其黄酮含量增加。荞麦中黄酮化合物的形成主要受苯丙氨酸解氨酶(PAL)活力的调控。

Abstract: The highest flavone content of buckwheat is in its flowers, and the mean value is as high as 7.4%. After flowering, the value will decrease gradually. The flavone content of buckwheat leaves is lower, and its mean value is 5.3%, and its highest peak appears at the stage of flowering, then decreases slowly. The flavone content of buckwheat stems is the lowest, and its mean value is 1.0%, without obvious change in the whole growth of the plant. Among the buckwheat grains, tartarty buckwheat grains contain the highest flavone content, and the mean value is 2.02%. The mean flavone content value in common buckwheat is only 0.23%. Radiative treatment can increase the flavone content of buckwheat. The formation of flavonid compounds of buckwheat is mainly controlled by PAL activity.
