The desired extraction solvent, solid-liquid ratio, extraction temperature and extraction time of flavonoids extract in okra were determined through single factor experiment. On the basis of single factor test, the best extraction technique was determined by using flavonoids yield as evaluation through orthogonal test. Result: Factors influencing the extraction of flavonoidsin okra were ranked as Follows:Extraction temperature>extraction time>ethanol concentration>solid-liquid ratio. The optimum extraction method was:extraction time 30min, extraction temperature 40 ℃, solid-liquid ratio of 1 : 20(m/V)and 55% ethanol concentration. Using the optimized method, the extraction rate of flavonoidsin validation test reached 3 . 30%.
