Abstract

Four new isoindolinone derivatives, daldinans D‒G (36), together with two known compounds, daldinans A and B (1 and 2), were isolated from the stroma of the ascomycete Daldinia concentrica. Chemical structures of the isolated compounds were determined by spectroscopic methods. All of these compounds exhibited antioxidant activities with IC50 values of 3.21 to 39.67 µM in the 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assay.
