摘　　要：不同生长期的盘播荞麦苗,经预处理后采用分光光度法检测其中总黄酮的含量,以获得不同生长期养麦苗中总黄酮的含量变化趋势。结果表明:随着生长期的延长,养麦苗中黄酮类化合物的含量亦逐渐增高,直至生长到第17 d时其黄酮类化合物的含量达到最高值为10.56 mg/g。此后随着生长期的延长荞麦苗中黄酮类化合物的含量逐渐下降,但降幅较小。The total flavonoids in pretreated buckwheat seedling at different growing period were determined by absorption spectrometry to obtain the change tendency. The results indicated that the total flavonoids content gradually increased as the buckwheat seedling growing. The total flavonoids content in the buckwheat seedling achieved maximum of 10.56 mg/g on the 17th day of growing period. Afterwards it gradually decreased within a narrow range.
