[摘要]:Four novel sesquiterpenes, 5-hydroxydichomitol (1), dichomilludol (2), 3 beta,13-dihydroxyledol (3), and 2 beta,3 beta,13-trihydroxyledol (4), were isolated along with 2 beta,13-dihydroxyledol (5) from the AcOEt-soluble fraction of the mycelial solid cultures of Dichomitus squalens. Their structures were determined on the basis of spectroscopic analyses. The previously assigned structure of dichomitol was revised. |
