摘要:
The structures of sulcatine B, 5-epi-armillol and armillol, three protoilludene sesquiterpenes isolated from still liquid cultures of Laurilia sulcata, have been assigned on the basis of one- and two-dimensional (HETCOR and COLOC) H-1 and C-13 NMR studies. The relative configuration of the metabolites was deduced from NOE experiments and the magnitude of the H-1-H-1 coupling constants.
