Abstract
Ten aromatic metabolites with the phenalene skeleton have been isolated as permethylated derivatives from the ethyl acetate extract of the aquatic plant Eichhornia crassipes. Beside the already described monomeric lachnanthocarpone red dimethyl ether,4,9-dimethoxy-7-phenyl-2,3-dihydro-phenalen-1-ol-O-methyl,4,9- dimethoxy-7-(4′-methoxy-phenyl)-2,3-dihydro-phenalen-1ol-O-methyl and 4,5-dimethoxy-9-phenyl-2,3-dihydro -phenalen-1-ol-O-methyl, six new dimeric compounds have been characterized. The structures have been deduced on the basis of the data of these compounds. © 1992.File in questo prodotto:
