Summary:A method for extracting ganoderma triterpene and ganoderma lucidum polysaccharide from ganoderma lucidum comprises the steps as follows: (1) pretreatment of raw materials: placing crushed ganoderma lucidum fruiting bodies in a sodium hydroxide-aqueous solution for extraction, and performing filtration after ultrasonic treatment to obtain a filtrated material and an extract liquid; (2) pH adjustment: adjusting pH of the extract liquid to 2.0-4.5; (3) dynamic reflux adsorption: performing dynamic reflux adsorption on the extract liquid obtained in step B, and after adsorption, collecting an effluent I; (4) staged elution: dividing the elution process into four stages, mixing and collecting eluates III at the first three stages, and collecting an eluate III which is a ganoderma triterpene extract liquid at the fourth stage; (5) mixing the effluent I and the eluates II, adding ethanol for ethanol precipitation, and performing filtration, drying and crushing to obtain crude ganoderma lucidum polysaccharide.
