A new chromone and a new aliphatic ester were isolated from the EtOAc extract of myceliums of Daldinia eschscholtzii. Their structures were elucidated as (R)-5-hydroxy-8-methoxy-2-methylchroman-4-one (1) and (E)-6-(non-3-en-1-yl) -2H-pyran-2-one (2) by interpretation of the spectroscopic evidence.
Keywords: (E)-6-(non-3-en-1-yl)-2H-pyran-2-one; (R)-5-hydroxy-8-methoxy-2-methylchroman -4-one; Daldinia eschscholtzii.
