Abstract In addition to some previously described 7,8-dioxy-isoflavonoids and 2-benzylbenzo[ b ]furan-3 (2H)-ones the heartwood of Xanthocercis zambesiaca has been shown to contain 7,8,3′-trihydroxy-4′-methoxyisoflavone. These are accompanied by the novel α,3,4,4′-tetrahydroxy-2′-methoxydihydrochalcone and its 3-deoxy analogue, the latter of which presumably served as biogenetic precursor for the unique
摘要 除了一些先前描述的 7,8-二氧基-异黄酮和 2-苄基苯并[b]呋喃-3 (2H)-ones 之外,赞比亚黄尾草的心材已被证明含有 7,8,3'-trihydroxy-4' -甲氧基异黄酮。这些伴随着新的 α,3,4,4'-四羟基-2'-甲氧基二氢查耳酮及其 3-脱氧类似物,后者可能是独特的 1-羟基-3-(4-羟基苯基)-1-(4-羟基-2-甲氧基苯基)丙-2-酮及其1-脱氧类似物。这种可能的生物合成关系通过适当的 α-羟基二氢查耳酮在体外轻松转化为不同的 1,3-二芳基丙-2-酮来证明。
