The chemical investigation of an extract of the aerial parts of Centaurea amanicola
afforded several compounds including flavon (apigenin), coumarin (scopoletin),
triterpen (α-amyrin), steroid (β-sitosterol) and six aromatic compounds (vanilic acid, phydroxybenzoic acid, benzyl-β-D-glucoside, 2-phenylethyl-β-D-glucoside, 4'-fomyl-2',6'-dimethoxy-n-heptanophenone and 4'-formil-n-heptanophenone). This is the firstreport on the chemical constituents of Centaurea arnanicola. The structures of the compounds were determined by spectroscopic methods such as UV, IR, 'H and 13C NMR spectroscopy as well as mass spectrometry.
