✦ Synopsis

An array of one-and two-dimensional NMR techniques (APT, DEPT, COSY, NOESY, HMQC and HMBC) was used to achieve the structural elucidation of some natural benzofuranoid and hydrofuran neolignans isolated from L icaria chrysophylla, L . armeniaca, L . aurea and Nectandra glabrescens fruits. The combination of homo-and heteronuclear NMR data was used to obtain the 1H and 13C chemical shift assignments of these neolignans.
