A dimeric ArC2 compound from Peperomia pellucida.

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