Six new neolignans, casearialignans A–F ( 1 – 6 , resp.) and one known lignan syringaresinol‐ β ‐ D ‐glucoside were isolated from the leaves of Casearia sylvestris. Their structures were determined on the basis of 1D‐ and 2D‐NMR, and HR‐ESI‐MS analyses. The relative and absolute configurations were determined by the value of the coupling constants and CD spectral analysis, respectively.
