A new arylnaphthalene lignan from Knema furfuracea

A new aryl naphthalene lignan, named furfuracin (1), was isolated from the leaves of knema furfuracea (Myristicaceae), whereas 7 known compounds including (+)-trans-1,2-dihydrodehydroguaiaretic acid, fragransin A(2), biochanin A, gingkolic acid, anarcardic acid, 2-hydroxy-6-(12-phenyldodecyl)benzoic acid and 2-hydroxy-6-(12-phenyldodecen-8'Z-yl)-benzoic acid were obtained from its stems. The structure of the new lignan was established by analysis of spectroscopic data (UV, IR, MS and NMR). (C) 2009 Elsevier B.V. All rights reserved.
