Summary:The invention discloses a method for extracting coreopsis tinctoria procyanidins and an application of the coreopsis tinctoria procyanidins in delaying senescence. The method comprises the following steps: extracting coreopsis tinctoria procyanidins from the raw material coreopsis tinctoria which grows 2600m over the sea level by adopting a dynamic high-pressure microfluidization assisted extraction technology for 30 minutes with 70% ethanol at the extracting pressure of 120MPa and the extracting temperature of 50 DEG C, and treating the coreopsis tinctoria twice by means of microjet pressure. The total antioxidation activity of the prepared procyanidins is higher than that of ascorbic acid, and has an effect of delaying senescence of drosophila melanogaster by combining results of drosophila melanogaster surviving experiments and in-vivo biochemical index detection; liver injury experiments in mice indicate that the procyanidins extracted from coreopsis tinctoria is capable of reducing the activities of ALT
