摘要：
We determined the allelochemicals produced by Fimbristylis miliacea and their allelopathic potential against 4-weed species (Ludwigia hysopifolia, Echinochloa colonum, Cyperus iria and Paspalam digitatum). Two allelochemicals (hexanedioic acid dioctyl ester and di-n-octyl phthalate) were isolated from the F. miliacea using a bioassay-guided isolation method. The compounds were isolated and identified by GC-MS (Gas chromatography-mass spectrometry). Both compounds reduced the germination of all test weed species. Hexanedioic acid dioctyl ester was found more toxic than di-n-octyl phthalate.
