利用比色法和高压液相色谱法对在我国16个省采集的40个不同样品玉米须黄酮类总量和黄酮类单体化合物的含量进行了测定。结果表明，玉米须黄酮类总量随品种的不同差异很大，含量从不足0.1%到3%以上。黄酮类单体化合物的含量随品种的不同差异很大，化合物A、B、C、D、E的含量范围分别为：0～0.188%、0～0.149%、0～0.028%、0～0.045%、0～0.040%。

The five flavonoids monomers and total flavonoids content in forty corn silk samples collected from sixteen provinces in China were analyzed by HPLC and colorimetric methods. The results showed that there was a wide range of flavonoids levels in the corn silk, total flavonoids , from 0.1% to 3.0% dry weight; compound A, from 0 to 0.188%; compound B, from 0 to 0.149%; compound C, from 0 to 0.028%; compound D, from 0 to 0.045%; compound E, from 0 to 0.040%.
