The invention discloses a production process for quickly and easily extracting a plant flavone compound. The process comprises 1, soaking, namely wetting dried buds and fruit after plant harvest by spraying an aqueous solution; 2, crushing, namely crushing the wetted buds and the fruit obtained in the step 1; 3, stewing, namely stewing the crushed buds and fruit raw materials obtained in the step 2 at high temperature for 30 to 60 minutes; 4, performing eluting and chromatography infiltration, namely eluting the material stewed at the high temperature by using weak base, performing chromatography infiltration, adjusting the pH value of the leachate, precipitating and crystallizing the flavone compound; 5, filtering a crystalline solution, and washing crystalline solids to obtain a crude product; and 6, drying and crushing the crude product to obtain the product. According to the process, an enzyme is inactivated at the high temperature, impurities are removed by using weak base, the flavonoid compound is easily susceptible to open-loop and soluble in the aqueous solution under an alkaline condition, and aqueous alkali at low concentration is subjected to low pressure chromatography to quickly prepare the flavonoid compound; requirements on equipment under low pressure are low, and the fixed production input can be reduced. Through chromatography under certain pressure, separation efficiency is improved.
