Abstract

Four new flavonoid glycosides, quercetin 3-O-beta-D-xylopyranosyl-(1-4)-beta-D-glucopyranoside, quercetin 3-O-beta-D-apiofuranosyl-(1-4)-beta-D-glucopyranoside, kaempferol 3-O-beta-D-apiofuranosyl-(1-4)-beta-D-glucopyranoside, and kaempferol 4'-methyl ether 3-O-beta-D-xylopyranoside, along with other known flavonoids and phenolic derivatives, were isolated from the leaves of Vernonia ferruginea Less. Their structures were established on the basis of detailed spectral analysis.

摘要

从锈毛斑鸠菊（Vernonia ferruginea Less.）的叶子中分离出四种新的黄酮苷，即槲皮素3 - O - β - D - 吡喃木糖基 -（1→4）- β - D - 吡喃葡萄糖苷、槲皮素3 - O - β - D - 阿糖呋喃糖基 -（1→4）- β - D - 吡喃葡萄糖苷、山奈酚3 - O - β - D - 阿糖呋喃糖基 -（1→4）- β - D - 吡喃葡萄糖苷和山奈酚4'-甲基醚3 - O - β - D - 吡喃木糖苷，以及其他已知的黄酮类化合物和酚类衍生物。它们的结构是在详细的光谱分析基础上确定的。
