Pellucidin A, a novel dimeric ArC2 compound, together with dill-apiol have
been isolated from the aerial parts of Peperomia pellucida. The structure o
f pellucidin A was established by 1D and 2D NMR spectroscopy (H-1-H-1 COSY;
H-1-C-13 COSY; DEFT; NOESY and double irradiation) and other spectroscopic
techniques. The biogenesis of pellucidin A is also briefly discussed. (C)
