Interpretive Summary: Six new neolignans, casearialignans A-F (1-6) and one known lignan syringaresinol-ß-D-glucoside were isolated from the leaves of Casearia sylvestris. Here, we report the isolation and structure elucidation of the new neolignans.

Technical Abstract: Six new neolignans, casearialignans A-F (1-6) and one known lignan syringaresinol-ß-D-glucoside were isolated from the leaves of Casearia sylvestris. Their structures were determined on the basis of 1D and 2 D NMR and high resolution ESI-MS spectroscopic analyses. The relative and absolute configurations were determined by the value of coupling constant and CD spectral analysis respectively.
