Abstract
A new isoindole alkaloid, 6-hydroxy-2-(4′′′-hydroxy-3′′′-methoxyphenethyl)-4-(4′-hydroxy-3′-methoxyphenyl)-7-methoxy-1H-benzo[f]isoindole-1,3(2H)-dione, named oleraisoindole B was isolated from Portulaca oleracea L., its structure was elucidated using NMR and UHPLC-ESI-Q-TOF/MS spectroscopic methods, and presented anti-inflammatory activity at 5 μM.
