The chemical constituents of the wood of Xanthoxylum nitidum (ROXB.) D. C.(Fagara nitida ROXB.) were examined. Two phenylpropanoids, methyl nitinoate (2) and dihydrocuspidiol (3), and a benzodioxane type lignan, nitidanin (4), were newly isolated. The structures of the phenylpropanoids were chemically determined. In addition, the application of a selective insensitive nuclei enhanced by polarization transfer selective (INEPT) technique in the NMR spectrum to the new lignan allowed us to deduce the structure.
