用ＨＰＬＣ检测了不同光照处理大豆组织中异黄酮的含量。结果显示：幼苗子叶异黄酮含量大大高于叶片和根中的含量；光照处理后，子叶中异黄酮的含量降低，而叶片和根中的异黄酮含量上升；异黄酮含量较低的品种，幼苗光照后子叶中异黄酮含量上升较多。幼苗子叶中的异黄酮以大豆甙和染料木甙及其丙二酰衍生物为主，叶片中主要含有染料木甙及其丙二酰衍生物，根中异黄酮组分以丙二酰大豆甙为主；异黄酮组分因品种不同显示出一定差异。
The contents of isoflavones in different light-treated soybean tissues were detected by HPLC. The results showed that the content of isoflavones in seedling cotyledons was much higher than that in leaves and roots. After light treatment, the content of isoflavones in cotyledons decreased, while the content of isoflavones in leaves and roots increased. The varieties with lower isoflavone content and seedlings Cotyledon after isoflavone content increased more. Isoflavones in seedling cotyledons with daidzein and genistin and malonyl derivatives mainly containing genistein and malonyl derivatives, root isoflavone component to malonyl daidzin Mainly isoflavone components due to different varieties showed some differences.
