Abstract: Characteristic color reactions and UV-visible spectra analysis for petal pigments of Osmanthus fragransSiji Gui and extraction methods for flavonoids and carotenoids from its flower were studied using single factor and orthogonal tests. Results for flavonoids showed a characteristic absorption peak of 320 nm with optimum extraction conditions being an immersion in 50% (V/V) ethanol aqueous solution at 45 ℃ for 3 h with a solid-liquid ratio of 1(g) ∶ 20 (mL). For three common carotenoid compounds the characteristic absorption peaks were:lutein (443 nm),lycopene (472 nm),and carotene (502 nm) with the best extraction conditions being immersion in acetone:ethanol(1 ∶ 1) solution at 50 ℃ for 3 h with a solid-liquid ratio of 1(g) ∶ 10(mL).[Ch,3 fig. 5 tab. 17 ref.]
