BACTERIOSTATIC HETEROCYCLES FROM EUODIA LUNU-ANKENDA

Article abstract of DOI:10.1016/S0031-9422(00)80844-4

A new constituent characterized as 8-acetyl-3,4-dihydroxy-5,7-dimethoxy-2,2-dimethylchroman has been isolated together with alloevodionol-7-methyl ether, 4-methoxy-1-methyl-2(1H) quinolinone, evolitrine, isoevodionol and its methyl ether from the aerial parts of Euodia lunu-ankenda.Its structure was confirmed by its transformation to alloevodionol-7-methyl ether. 4-Methoxy-1-methyl-2(1H)quinolinone and its isomer were synthesized by a modified procedure.Key Word Index - Euodia lunu-ankenda; Rutaceae; 8-acetyl-3,4-dihydroxy-5,7-dimethoxy-2,2-dimethylchroman; alloevodionol-7-methyl ether; 4-methoxy-1-methyl-2(1H)quinolinone; isoevodionol; isoevodionol methyl ether; antibacterial activity.
