Abstract
An array of one- and two-dimensional NMR techniques (APT, DEFT, COSY, NOESY , HMQC and HMBC) was used to achieve the structural elucidation of some nat ural benzofuranoid and hydrofuran neolignans isolated from Licaria chrysoph ylla, L. armeniaca, L. aurea and Nectandra glabrescens fruits. The combinat ion of homo- and heteronuclear NMR data was used to obtain the H-1 and C-13 chemical shift assignments of these neolignans. (C) 1998 John Wiley & Sons , Ltd.
