Abstract
Two new isobenzofuranone derivatives erinaceolactones G and H (1 and 2) were isolated from the ethanolic extract of fruiting bodies of Hericium erinaceus. Their structures were characterized on the basis of spectroscopic evidences. Compound 2 was suggested to be racemic by specific rotation, which was resolved by chiral HPLC into enantiomers.
