Mauritianin and (+)-syringaresinol as new topoisomerase I inhibitors. Mauritianin has statistically significant cytoprotective activity similar to that of silymarin, tested at 60 ug/mL.

Bioassay-guided fractionation resulted in the isolation of Mauritianin and (+)-syringaresinol as new topoisomerase I inhibitors, and also of the known inhibitor camptothecin.
