Two Pyrone Derivatives from Fungus Phellinus Igniarius
2003
Two new pyrone derivatives phelligridins A 1 and B 2 were isolated from the fruit body of Phellinus igniarius. Their structrues were elucidated as 8, 9-dihydroxy-3-methyl-1H,6H- pyrano[4,3-c][2]benzopyran-1,6-dione and 4-hydroxy-6-(3',4'-dihydroxystyryl)-3-methoxycarbon- yl-2-pyrone , respectively, by means of spectral methods, including IR, MS, 1D and 2DNMR spectra.
