Abstract
Cuparene-type sesquiterpenes were isolated from a culture broth of Flammuli na velutipes (Curt.:Fr.) Sing. Using spectroscopic methods (HR-MS,H-1 and C -13 NMR, and 2D NMR, spectroscopy), their structures were determined to be 2,3,4,5-tetrahydro-2,7-dihydroxy-5,8,10,10-tetramethyl-2,5-methano-1-benzox epin and 5-methyl-2-(3-oxo-1,2,2-trimethylcyclopentyl)benzoquinone. Both sh owed antimicrobial activity against Cladosporium herbarum and Bacillus subt ilis. (C) 2000 Elsevier Science Ltd. All rights reserved.
