Two new isobenzofuranone derivatives, polyphthaliside A () and polyphthaliside B (), and a new isocoumarin derivative, polyisocoumarin (), were isolated from . Their structures were elucidated by detailed spectroscopic analysis and chemical methods. The cytotoxicity activity and PTP1B inhibitory activity of compounds 1-3 were estimated and none of them exhibited activities at a concentration of 10 M.
