wedeloside, a new flavanone, 7,4′-dihydroxy-8,3′-dimethoxyflavanone and its related chalcone, together with the 4′- O -β- d -glucopyranoside of the latter, and a number of known compounds were isolated from the aerial parts of Wedelia asperrima . Their structures were established by spectroscopic techniques and by synthesis of the flavanone and chalcone.
摘要 韦德洛苷的 4'-O-硫酸化类似物、新的黄烷酮、7,4'-二羟基-8,3'-二甲氧基黄烷酮及其相关查耳酮,以及后者的 4'-O-β-d-吡喃葡萄糖苷,并且从 Wedelia asperrima 的地上部分分离出了许多已知的化合物。它们的结构是通过光谱技术和黄烷酮和查耳酮的合成确定的。
