An unusual tetrahydrofuran lignin, zanthplanispine (1), together with 14 known lignans (2 - 15) were isolated from the AcOEt-soluble fraction from the MeOH extract of Z. planispinum roots. The structures of 1 was elucidated on the basis of 1D- and 2D-NMR experiments as well as HR-ESI-MS analysis. The known compounds were identified by the comparison of their NMR data with previously reported in the literatures. Bioassay showed that compounds 1 - 4 could inhibit nitric oxide (NO) production in lipopolysaccharide (LPS) stimulated RAW 264.7 cells. In particular, compound 1 showed significant inhibitory activity with an IC50 value of 36.8 μm.
