摘要
Bioassay guided fractionation of the dichloromethane extract of the underground parts of Gethyllis ciliaris, using a cyclooxygenase-1 enzyme assay, has resulted in the isolation of the dihydroxydimethylbenzopyran-4-one isoeugenitol 1 (IC50 = 262 mu M). The 90% methanolic extract yielded 9Z-octadec-9-enamide 3 and the novel compound isoeugenitol glycoside 2. The structures of the isolated compounds have been assigned on the basis of spectral analysis, including 1D and 2D NMR techniques. (c) 2006 SAAB. Published by Elsevier B.V. All rights reserved.
