While lentil (Lens culinaris) seeds are phytochemically well characterized, very little is known about secondary metabolites from lentil roots. Our research on lentil roots led to isolation of five phenolic compounds and five group B soyasaponins. Their structures were established using NMR spectroscopy and mass spectrometry. Four phenolics have not been hitherto described in the literature: 4‐O‐β
尽管扁豆(Lens culinaris)种子在植物化学上具有良好的特征,但对来自扁豆根的次生代谢产物了解甚少。我们对小扁豆根的研究导致分离出5种酚类化合物和5种B组大豆皂苷。它们的结构是使用NMR光谱和质谱法确定的。四种酚类没有在文献中进行了说明:4- ø - β - d吡喃葡萄糖基-2-甲氧基苯甲酸,(αS)-4,4'-二- ø - β - d -glucopyranosyl- α,2'-二羟基二氢查耳酮((αS)‐4′‐ O ‐ β ‐ d-吡喃葡萄糖基-α,2',4-三羟基二氢查尔酮和酮基-2-羟基糖精。还评估了纯化酚类化合物的DPPH ∙ 清除自由基的活性。
