The invention discloses a method for separating and extracting chrysanthemum volatile oil, fiavonoid and phenolic acids from chrysanthemum. The method comprises the following steps: (1), crushing chrysanthemums dried in the shade, packaging the crushed chrysanthemums with filter paper, placing the packaged chrysanthemums into a soxhlet extractor, adding a low-boiling-pint organic solvent to carry out continuous refluxing and extracting until the color of the solvent is not increased, placing an extract into a rotary evaporator and volatilizing the organic solvent; then, adding distilled water and mixing, distilling in water, collecting the chrysanthemum volatile oil, after adding anhydrous sodium sulfate to dehydrate, and sealing and storing at a low temperature; (2), after volatilizing the organic solvent from the chrysanthemum residue, adding alcohol 8-12 times the amount of the residue to extract for 1-3 times, combining filtrates, recycling alcohol under reduced pressure, concentrating, freeze-drying, sea
