Zusammenfassung:Mycelium of Inonotus rheades (Pers.) Bondartsev & Singer (Hymenochaetaceae) grown with illumination by blue light contained p -hydroxybenzoic acid 4- O -glucoside, protocatechoic acid 4- O -glucoside, p -coumaric acid 4- O -glucoside, caffeic acid 4- O -glucoside, and the new styrylpyrone glycosides 1 and 2 . According to UV, IR, and NMR spectroscopic and mass spectrometric data, the new compounds were hispidin 4′- O - β -D-glucopyranoside (rheadoside A, 1 ) and bisnoryangonin 4′- O - β -D-glucopyranoside (rheadoside B, 2 ), which could inactivate superoxide radicals.
