Publication number: 20240132928Abstract: The present invention provides a Ganoderma lucidum ?-glucan extract, a preparation method and detection method therefor. The preparation method includes: S1: crushing fruiting bodies of Ganoderma lucidum, mixing the crushed fruiting bodies with a solvent, adding trypsin for enzymatic hydrolysis for 0.5-2 h, and separating to obtain a Ganoderma lucidum fruiting body filter residue; S2: mixing the Ganoderma lucidum fruiting body filter residue with an alkali solution, carrying out ultrasonic extraction with heating, adjusting the pH value of the obtained filtrate to be neutral, and concentrating to obtain a crude Ganoderma lucidum polysaccharide; S3: carrying out alcohol precipitation on the crude Ganoderma lucidum polysaccharide, separating the obtained precipitate, and freeze-drying to obtain a crude Ganoderma lucidum ?-glucan extract; and S4: purifying the crude Ganoderma lucidum ?-glucan extract by glucose gel column chromatography to obtain a Ganoderma lucidum ?-glucan extract.Type: ApplicationFiled: October 17, 2023Publication date: April 25, 2024Inventors: Chengyuan LIANG, Boxin ZHANG, Changhua KE, Shan YANG, Jingjing ZHOU, Jinrong HU, Yuting LIU

Patent number: 11434889Abstract: A piston-cylinder structure includes a cylinder, an end cap, a tapered portion for extruding dead space, an upper bowl-shaped seal portion, a columnar seal portion, a lower bowl-shaped seal portion and a piston push rod. The upper bowl-shaped seal portion is configured to form sealing between the piston push rod and the cylinder when the piston push rod moves toward the end cap and to remove crystals on an inner wall of the cylinder. The columnar seal portion is configured to enable the piston push rod to be coaxial with the cylinder, and to provide a mechanical support for the piston push rod. The lower bowl-shaped seal portion is configured to provide sealing between the piston push rod and the cylinder and remove the crystals on the inner wall of the cylinder when the piston push rod moves toward the end cap.Type: GrantFiled: June 24, 2020Date of Patent: September 6, 2022Assignees: BEIJING BEIFEN-RUILI ANALYTICAL INSTRUMENT (GROUP) CO., LTD., MAITUOWEI PRECISION INSTRUMENT MANUFACTURING HEBEI CO., LTD.Inventors: Lu Chen, Jiaxiang Deng, Rongbing Tian, Sainan Li, Jinrong Liu, Hongxiang Shu

Publication number: 20150207139Abstract: A composition, method of its preparation, and zinc electrodes comprising the composition as the active mass, for use in rechargeable electrochemical cells with enhanced cycle life is described. The electrode active mass comprises a source of electrochemically active zinc and at least one fatty acid or a salt, ester or derivative thereof, or an alkyl sulfonic acid or a salt ester or derivative thereof. The zinc electrode is assumed to exhibit low shape change and decreased dendrite formation compared to known zinc electrodes, resulting in electrochemical cells which have improved capacity retention over a number of charge/discharge cycles.Type: ApplicationFiled: December 8, 2014Publication date: July 23, 2015Inventors: Simon Berners HALL, Jinrong Liu
