Complete assignments of 1H and 13C NMR data for three new arylnaphthalene lignan from Justicia procumbens

Magn Reson Chem. 2008 Mar;46(3):283-6. doi: 10.1002/mrc.2175.

Abstract

Three new arylnaphthalene lignans, named neojusticin C (1), procumbenoside C (2) and procumbenoside D (3), have been isolated from the whole plant of Justicia procumbens, together with three known ones, justicidinoside B (4), justicidinoside C (5), and diphyllin-1-O-beta-D-apiofuranoside (6). The complete assignments of 1H and 13C NMR data for three new lignans were first obtained by means of 2D NMR techniques, including HSQC and HMBC.
