Total flavonoids in lyciumruthenicummurr as well as extraction method and application thereof

The invention discloses total flavonoids in lyciumruthenicummurr as well as an extraction method and application thereof. The method comprises the following steps: cleaning and drying lyciumruthenicummurr, and crushing the cleaned lyciumruthenicummurr for later use; with choline chloride type eutectic solvent as an extracting agent, carrying out auxiliary extraction to obtain a flavone extractingsolution under the condition that a hydrogen bond receptor for synthesizing the eutectic solvent is choline chloride and a hydrogen bond donor is at least one of levulinic acid, lactic acid, ethyleneglycol, urea and 1, 3-butanediol in the choline chloride type eutectic solvent; adsorbing the flavone extracting solution by adopting macroporous resin and carrying out separation and purification byusing an organic reagent to obtain a purified flavone extracting solution; and carrying out rotary evaporation on the purified flavone extracting solution and adding polyethylene glycol, and carryingout vacuum freeze drying to
