| Abstract: | Effect of solvent, soking temperature, extracting time and ratio of materio to liquid on the yield of onin oil was studied. When choosing ethyl acetate as the solvent, soak onion at 40℃ , extraction time was 120 min and liquid ratio is 1：1.25, the extraltion rate of onion oil can be achieved 0.19%. The optimum ultrasonic extraction condition for flavonoids was ultrasonic temperature 40 ℃ for 15 rain, ethanol concentration 80% and liquid ratio 1：10. |
