A new neolignan, paniculignan (1), and a known lignan, tetracentronside B (2), were isolated from Panicum turgidum. The structure of 1 was elucidated by extensive spectroscopic methods including 1D and 2D NMR and HR-ESI-MS. The relative configuration of 1 was determined on the basis of circular dichroism spectroscopy, optical rotation, and NOESY correlations.
