Abstract

Twelve sesquiterpenes comprising either the protoilludane or the rare cerapicane carbon skeletons were obtained from the saprotrophic wood decomposing fungus Granulobasidium vellereum; 2a-hydroxycoprinolone (1), 3-hydroxycoprinolone (2), coprinolone dial B (3), granulodiene A (4), granulodiene B (5), granulone A (6), 8-deoxy-4a-hydroxytsugicoline B (7), granulone B (8), demethylgranulone (9), cerapicolene (10), as well as the known compounds radudiol and Delta(6)-coprinolone. The structures were determined using spectroscopic methods and biosynthetic considerations. Granulone A had growth stimulating effect on the total elongation of lettuce. seedlings. None of the isolated compounds showed any antifungal effect. (C) 2014 Elsevier Ltd. All rights reserved.
