- Abstract
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 from alkaline hydrolysis of the compounds.
