Three new furofuran lignans, (+)‐4,4′‐O‐diangeloylpinoresinol (1), (+)‐4,4′‐O‐diangeloylmedioresinol (2), and (+)‐4,4′‐O‐diangeloylsyringaresinol (3), together with the known compound (+)‐syringaresinol, were isolated from the MeOH extract of Rudbeckia laciniata. The structure elucidation of these compounds were based on 1D‐ and 2D‐NMR, and HR‐ESI‐MS data. The additional structural evidence was obtained
三种新的呋喃呋喃木脂素((+)‐ 4,4' - O-双-二烯基壬二醇(1),(+)‐ 4,4' - O-双-二烯基间苯二酚(2)和(+)‐ 4,4' - O-二邻苯二甲酰基丁香酚醇(3)与已知化合物(+)-丁香油素醇一起从黄金菊的MeOH提取物中分离出来。这些化合物的结构解析基于1D-NMR和2D-NMR,以及HR-ESI-MS数据。从化合物的碱水解获得了额外的结构证据。
