The invention relates to a method of extracting isoquercitrin, senecio cannabifolius less glycoside and senecio cannabifolius less polysaccharide from senecio cannabifolius less, wherein the isoquercitrin has the effects of stopping bleeding and reducing blood pressure, resisting inflammation and killing virus; the senecio cannabifolius less glycoside has the effects of relieving a cough and diminishing inflammation, and resisting tumors and lung cancer; and senecio cannabifolius less polysaccharide has the effect of enhancing the immunity. The conventional senecio cannabifolius less extract production technique still has more limits and deficiencies, different substances in the extracting product can not be effectively separated, and only one product is obtained. Three effective products can be obtained by adopting methods of supercritical CO2 extraction, normal-temperature ethanol digestion, macroporous resin adsorption and the like through one production technique. The method is simple in flow process and
