Chemical investigation of the methanolic extract from the fruiting bodies of Hericium erinaceus, led to the isolation of fifty-one compounds including thirty-five ergostane-type sterols (1–35), fourteen aromatic compounds (36–49), and two cerebrosides (50 and 51). Their structures were identified based on spectroscopic analyses and by comparison of their spectral data with those reported in literature. This is the first comprehensive low-polarity chemical investigation of H. erinaceus. Thirty-one of the compounds (6–8, 11–35, 39, 41, and 49) were isolated for the first time from the genus Hericium and the family Hericiaceae. The chemotaxonomic relationship between H. erinaceus and other Hericium species was also discussed.
