丙二酰,丙二酰基
Major isoflavone in cotyledons, leaves and roots were daidzin and genistin and their derivatives, genistin and its malonyl derivatives, and malonyl daidzin, respectively. 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；
Then succinate dehydrogenase, SDH activity, malonyl dialdehyde, MDA concentration, water content and morphological change of wound tissue were observed dynamically. 而创面过氧化脂质含量及含水量治疗组低于对照组，在伤后8，24及48小时两组均有显著差异；
Soy hypocotyls contained a lot of isoflavones, existing mainly in malonyl isoflavone glycosides.This kind ofisoflavones showed mainly bitter and beany components in soy hypocotyls. 大豆胚芽含有大量异黄酮化合物,天然异黄酮存在形式主要丙二酰型糖苷,此类异黄酮化合物是大豆胚芽的苦涩、豆腥味的主要呈味物质。
