Abstract: The present invention relates to a preparation method of Agrocybe aegerita extract and its use in the preparation of lowering uric acid drugs, including: (1) Crush the dried fruit bodies of Agrocybe aegerita; (2) Separate the filter residue and the filtrate within 120 hours of extraction with 100-3000% ethanol by volume weight percentage at 0-100° C., and repeat it for 1-10 times; (3) Combine the filtrates obtained in step (2), concentrate to 25-35 mL and freeze-dry to obtain the alcohol extract; (4) Use 100-3000% water by volume percentage as a solvent to extract the alcohol-extracted filter residues of step (2) at 0-100° C. within 120 hours, separate the filter residue and the filtrate, repeat it for 1-10 times; (5) The filtrates obtained in step (4) are combined and concentrated to 25-35 mL, and lyophilized to obtain the water extract.

Abstract: The present invention discloses a process for preparing a functionalized choline chloride ionic liquid as defined in formula (I), and thereof use in an electrochemical energy storage device, as an electrolyte solution or an additive for a lithium ion battery and a supercapacitor. The ionic liquid electrolyte material has better biocompatibility, flame retardance, high ionic conductivity, low viscosity, and wide electrochemical window. wherein R1 is selected from the group consisting of: (CH2?CH—(CH2)n)—, CN(CH2)n—, or R23Si—; R2 is selected from CH3—(CH2)m—, n is an integer selected from 1 to 3, m is an integer selected from 0 to 2; or one of R2 is (CH3)3Si—O—. Anion A in Formula I is selected from the group consisting of: Cl?, Br?, I?, BF4?, NO3?, SO42?, CF3COO?, CF3SO3?, (CF3SO2)2N?, PF6?, BF2C2O4?, or B(C2O4)2?.
