Problems solved by technology

[0012] However, these methods are still not accurate and simple enough, and the specificity is not strong. With the wide application of glucosamine in food, health food and medicine, it is necessary to establish a set of relatively fast, simple and accurate analysis methods for the determination of glucosamine. quantitative analysis

experiment example 1

[0027] Experimental Example 1-Selection of High Performance Liquid Chromatography Conditions

[0028] Instruments and reagents: Japan Shimadzu LC-10A high-performance liquid chromatograph and ultraviolet detector are used. The control and recording of the chromatographic separation system are completed by the Wemaron chromatographic workstation. Glucosamine hydrochloride reference substance was purchased from China National Institute for the Control of Pharmaceutical and Biological Products; glucosamine hydrochloride samples were purchased from Zhejiang Chengyi Pharmaceutical Co., Ltd.; It was ultrapure water, and other reagents were of analytical grade.

[0029] Column: Ultimate from Welch Materials TM XB-NH2, 5μm, 4.6×250mm; column temperature: 30°C.

[0030] Detection wavelength: Glucosamine hydrochloride has no characteristic absorption peak, and the ultraviolet absorption is in the terminal ultraviolet region, so 195nm is selected as the detection wavelength.

Description

technical field [0001] The invention relates to the field of analytical chemistry, in particular to an analysis method for glucosamine. Background technique [0002] Cartilage is composed of a small portion of chondrocytes and most of the cartilage matrix, which is composed of proteoglycans, collagen fibers, and water. Proteoglycan aggregates are composed of proteoglycans, and their main function is to form the matrix between cells, including the matrix in articular cartilage. It is a structural substance that supports and maintains the relationship between cells. part. It is also an important component of articular cartilage, and attracts a large amount of water molecules to form a gel. It forms a solid, network form of cartilage matrix together with collagen fibers, and bears the load during joint movement. Each proteoglycan aggregate is like a small spring, which has good elasticity and expansion ability, and plays a mechanical role in protecting joints. [0003] Prote...
