[Abstract]:OBJECTIVE: To obtain homogeneous polysaccharides from Buick Ginseng by extraction, isolation and purification, and to characterize the physicochemical properties and primary structure of homogeneous polysaccharides so as to lay a foundation for the study on the material basis of Buick Ginseng. Methods: (1) Response surface methodology and four factors and three levels of Box-Behnken central composite experimental design method were used to optimize the hot water extraction process of Polysaccharides from Buick Ginseng. DEAE Sepharose CL-6B and Sephadex G-100 were used to extract crude polysaccharides from Buick Ginseng. The purity and molecular weight of the purified polysaccharides were analyzed by high performance gel chromatography. (2) The contents of total sugar, glucuronic acid, starch and monosaccharide in the homogeneous polysaccharides were determined by phenol-sulfuric acid method, m-hydroxybenzene method, iodine coloration method, pre-column derivatization-HPLC method. Partial acid hydrolysis and NMR analysis were used to identify the structure of the homogeneous polysaccharides. (3) Carbon clearance test in mice was used to investigate the non-specific immune regulation function of Buick Ginseng crude polysaccharides on immunosuppressed mice. The effects of Polysaccharides from Buick Ginseng on the activity, phagocytosis, cytokine and mediator secretion of RAW264.7 cells were studied to investigate the immunomodulatory ability in vitro. Standard study: analysis of water and ash in 10 batches of Buickshen medicinal materials; establishment of microwave digestion ICP-MS method for determination of trace elements and heavy metals in Buickshen; establishment of acetonitrile ultrasonic extraction, GC-MS method for analysis of pesticide residues in Buickshen medicinal materials; establishment of Buickshen medicinal amino acid components, polysaccharide components TLC identification method; Results: (1) Response surface methodology was used to optimize the extraction process of crude polysaccharides from Buick Ginseng. The extraction time was 4.28 h, the extraction temperature was 90 ~C, the ratio of material to liquid was 37 ml/g, and the extraction times were 3 times. The yield (37.25%+0.17%) was in agreement with the predicted value of regression model (37.465%). After separation and purification of AE Sepharose CL-6B and Sephadex G-100, four homogeneous polysaccharides (ESBP1-1, ESBP1-2, ESBP2-1, ESBP3-1) were obtained. The molecular weights of these polysaccharides were 1.3 x 104, 1.7 x 104, 9.4 x 105, 4.1 x 105Da. (2) The results of phenol-sulfuric acid method showed that the total sugar contents of ESBP1-1, ESBP1-2-1, ESBP2-1 and ESBP3-1 were 97.8%, 98.7%, 99.3% and 97.0% respectively. The content of ESBP2-1, ESBP3-1 glucuronic acid was 0.02%, 1.9%, ESBP1-1 and ESBP1-2 were free of glucuronic acid, while the content of ESBP1-1, ESBP1-2 were 0.5%, 0.3%, 0.3%, ESBP2-1 and ESBP3-1 were not detected by hydroxybenzene method, respectively. ESBP3-1 was composed of glucose, galactose and arabinose (molar ratio 24.3:1.1:1), and ESBP3-1 was mainly composed of glucose and galactose (molar ratio 14.8:1); IR, Smith degradation, methylation, partial acid hydrolysis and NMR analysis showed that the structures of four homogeneous polysaccharides of Buicksan were similar, and the main chains of the four homogeneous polysaccharides were composed of (1_4) - alpha-D-Glcp. All the four homogeneous polysaccharides branched from the 6-O position and had different side chains. (3) Carbon clearance test in mice showed that the crude polysaccharides of Buick Ginseng could improve the organ index and monocyte-macrophage clearance index of immunosuppressed mice, suggesting that Buick Ginseng polysaccharides had some non-specific immunomodulatory function. Swelling, cotton ball granuloma and writhing test in mice induced by glacial acetic acid showed that the crude polysaccharide of Buick Ginseng had the ability to inhibit ear swelling, reduce the quality of granulation and writhing times, suggesting that Buick Ginseng polysaccharide had obvious anti-inflammatory and analgesic effects; in vitro cell experiments showed that Buick Ginseng crude polysaccharide ESBP and homogeneous polysaccharide ESBP1-1, ESBP1-2, ESBP2-1 And ESBP3-1 can promote the proliferation of RAW264.7 cells, increase their phagocytic activity, up-regulate the release of NO, IL-1 beta and TNF-alpha, showing immunopotentiatory effect; LPS-induced inflammatory response of RAW264.7 cells showed that Buickshen polysaccharide can inhibit the secretion of NO, IL-1 beta and TNF-alpha produced by LPS-induced excessive immunity, showing anti-inflammatory effect. METHODS: A TLC method for the determination of trace metal elements and pesticide residues in Buickshen was established. A TLC method for the identification of amino acids and polysaccharides in Buickshen was established. A method for the determination of polysaccharides in Buickshen was established. The draft quality standard of Buickshen and the drafting instructions were completed. Buick ginseng polysaccharides were extracted by DEAE Sepharose CL-6B and Sephadex G-100, and the established model was accurate and reliable, which could be used for the extraction process of Buick ginseng polysaccharides. (2) The crude polysaccharides were isolated and purified by DEAE Sepharose CL-6B and Sephadex G-100, and the method was feasible. The effect may be related to Buick Ginseng polysaccharide can promote cell proliferation, enhance phagocytosis and up-regulate cytokines and mediators; at the same time, Buick Ginseng polysaccharide has anti-inflammatory activity, which may be related to Buick Ginseng polysaccharide can inhibit the secretion of inflammatory factors and mediators caused by overimmunity. Keshen polysaccharide has two-way immunoregulation, and its anti-inflammatory activity is related to immunoregulation. (4) The quality standard of Bukeshen was established. The method was proved to be simple, stable and feasible by methodological investigation and systematic verification, which filled the blank in quality control of Bukeshen.
