Echinacea polysaccharides

Extractsource source: This product is a polysaccharide extracted from the roots of chrysanthemum plant narrow-leaf echinacea echinacea angustifolia DC, alfalfa pine chrysanthemum Echinacea purpurea (L.) Moench, with a total polysaccharide content of more than 60%the method of using alcohol for the solvent to extract the echinacea polyphenolafter raw material residue, boiling to extract polysaccharides, concentrated liquid ethanol precipitation, coarse polysaccharide degreasing, decolorization, de-protein, dialysis, spray drying, and finally added 10% water dry powder mixedcharacter" this product is light green to green yellow powder, soluble in hot wateridentification" take this product with methanol to make 27.0% solution for test ingeTake 1.0g of standard control of echinacea with methanol 30 ml, ultrasound extraction for 30 minutes, the filter concentrates to 1 ml for controlTake the above two liquid each 10 sl, respectively, point on the same silicone G board, a point two plate(1) to ethyl acetate-acetone-ice acetate-water (8;4:0.3:1), spray5% aluminum tetrachloride ethanol solution, UV lamp 365nm inspection(2) is expanded with cyclohetane-chloroform-aqueous ethanol (7:2:1), sprayed with 5% vanilla aldehyde sulfuric acid solution, and the hot wind is blownthe ratio of more than two plates, fluorescent spots and visible spots to 80%take this product and echinacea polysaccharide control products 20mg each, respectively, add 2mol/L sulphate 2ml, 110 degrees C hydrolyzed for 6 hours, with BaCO3 and to pH 6 to 7, centrifugation, upper liquid concentration To 1 ml, each take 10 sl, respectively, point on the same silicone G board, to chloroform-methanol-water (8:3:1) to expand, spray fennel-aldehyde sulfate test liquid, hot wind, speckle correspondence rate of 80%: Starch: No positive reaction (Appendix II)Moisture: No more than 4.0% (Appendix IX) H)Ash: No more than 3.0% (Appendix IX.K)Heavy Metals: No more than 10ppm (Appendix IX.E)arsenic salts: No more than 2ppm (Appendix IX.F)dextrin: not more than 0.5% (Appendix IV)determination) according to polysacchaecontent (Appendix III) determination, the total polysaccharide content is not less than 60% function sit uemes disease resistance storage is cool, dry and light-proof
