The flavones in the balls and leaves of platanus were extracted by microwave assisted cloud point extraction. Based on the single factor test, 0.6% tween-80 was applied to study the effects of microwave power, extraction time and liquid-solid ratio on extraction rate of total flavones. The optimal extraction conditions were as follows:microwave power 410 W, extraction time 7 min and liquid-solid ratio 49:1 mL/g, the average yield of flavonoids was 1.480mg/g. After separation and purification, two compounds were obtained from the flavones mixture, it was found that one compound is 3, 5, 7-trihydroxyflavone(C₁₅H₁₀O₅) and another compound is 3, 5, 7-trihydroxy-2-(4-hydroxyphenyl)-4H-chromen-4-one (C₁₅H₁₀O₆) by spectra analysis appraisal.
