The invention relates to a method for rapidly detecting the content of xanthophyll in fresh marigold flowers, which belongs to the technical field of natural plant content detection and comprises the following four steps: crushing petals and receptacles of the fresh marigold flowers; adding NaCl into the crushed sample, uniformly stirring, and extruding with filter cloth; adding an organic solvent aqueous solution into the extruded sample, uniformly mixing, carrying out suction filtration, and repeating the operation; accurately weighing the sample subjected to suction filtration, adding an organic solvent mixed solution into the sample, uniformly shaking, saponifying, cooling to room temperature, adding an organic solvent and an anhydrous sodium sulfate aqueous solution, uniformly shaking, splitting phases, diluting supernate, measuring the absorbance of a diluent, and calculating the content of xanthophyll. The method is simple to operate, low in cost, short in detection time and high in accuracy, is suitab
