New bicyclic [3.2.1] octane neolignan derivative from Aniba firmula.

bicyclic [3.2.1] octane neolignans have garnered increasing interest, because of their unique structural features and biological activities. This study describes the isolation and identification of a new bicyclic octane neolignan 1 obtained through fractionation of the crude extract of the stem of Aniba firmula (Lauraceae family). The structure of bicyclic octane neolignan 1 was determined through NMR analysis and mass spectrometry data.
