Abstract

Three novel lignans having unusual seco structure, peperomins A, B and C were isolated from the fresh whole plant of Peperomia japonica Makino (Piperaceae). The structures of peperomins A, B and C were established as I, II and III, respectively, on the basis of spectroscopic and crystallographic evidence.
