The patent discloses a method for efficiently collecting and purifying() germination stimulants using aeroponic system and solid-phase extraction (SPE), including the following steps: (1) sunflower seeds germination, then planting sunflower seedlings in aeroponic device, and cultivating the sunflower seedlings in the aeroponic system; at the aeroponic stage, phosphorus-containing aeroponic nutrient solution is first used to cultivate the sunflower seedlings for 20 to 25 days, and phosphorus-free aeroponic nutrient solution is then used instead to subject the sunflower seedlings to starvation cultivation for 5 to 7 days; and (2) passing all nutrient solutions in the aeroponic device through an SPE cartridge for SPE to extractgermination stimulants. The obtainedgermination stimulants are diversified, and have high concentration and purity.
