description The invention discloses a method for extracting flavone in platycodin grandifloras roots through microwave assistance, and belongs to the technical field of effective ingredient extraction of agricultural products. The method comprises the following concrete steps that (1) fresh platycodin grandifloras roots are cleanly cleaned, peeled and cut into slices; then, drying is performed at 60 DEG C toreach constant weight; after crushing, the materials pass through a 100 mesh sieve; (2) a certain quantity of platycodin grandifloras powder is taken; ethanol with the volume being 30 times and the concentration being 70 percent is added; (3) microwave treatment is performed for 60s under the condition that the microwave power is 420w; (4) extraction liquid is filtered; filter slag is repeatedly extracted; twice filtering liquid is merged; the whole platycodin grandifloras flavone leaching process is completed; the solution is subjected to rotary evaporation and freeze drying to obtain the platycodin grandifloras flav
