Embodiment 1
[0044] The extraction of embodiment 1 polygonatum polysaccharide
[0045] Mix 1 gram of Rhizoma Polygonatum with 8 grams of water, heat to boil and keep boiling for 60 minutes, separate the Rhizoma Rhizoma Polygonatum from the decoction, then mix the separated Rhizoma Rhizoma Polygonatum with another 8 grams of water, and repeat the above The process of heating and boiling and separating the Rhizoma Rhizoma Rhizoma Polygonatum and the decocted liquid is performed twice, and all the decocted liquids are combined.
[0046] Boil the combined decoction on high heat to concentrate, and when the ratio of medicine to liquid is 1:1, stop the concentration.
[0047] Adding the mass percent of ethanol in the concentrated medicinal solution is 95% ethanol aqueous solution, so that the mass percent of ethanol in the mixed solution after adding is 75%, (slowly and quickly stirring when adding ethanol aqueous solution helps to prevent the occurrence of coprecipitation) , after stirring eve...
Embodiment 3
[0051] The drawing of embodiment 3 standard curve
[0052] 1. References for the determination of the maximum absorption wavelength of Polygonatum polysaccharide [Imbety, Bourne Y, Cambillau C etal, Oligosaccharide Conformation in Protein Carbohydrate Computers, Adv. Biophys, Chem, 1993, 3: 71~117.] or [Yang Li, Wang Zhihua , Tao Jiansheng, etc. Comparison of Astragalus Polysaccharide Content Determination Methods in Radix Astragali [J]. Chinese Journal of Pharmaceutical Industry, 2005, 36 (9): 562-563], and obtained the ultraviolet absorption spectrum of Polygonatum polysaccharide, see figure 1 , where 625nm is the maximum absorption wavelength.
[0053] The determination of sugar content in the following examples in the present invention is all carried out at this wavelength.
[0054] 2. Preparation of glucose standard solution
[0055] Accurately weigh an appropriate amount of glucose standard substance that has been dried to a constant value, and add ultrapure water to d...
Embodiment 4
[0061] The purification of embodiment 4 polygonatum polysaccharide
[0062] NKA-9 macroporous adsorption resin was used as a filler, and the pretreatment in Example 2 was performed first, and then 2.0 g of the pretreated resin was wet-packed with ultrapure water. The column length was 50 cm and the column diameter was 2 cm.
[0063] The Polygonatum polysaccharide crude product obtained through the method of Example 1 is formulated with ultrapure water into a medicinal solution of crude Polygonatum polysaccharide with a concentration of 3.90 mg / mL, and 10 mL of it is taken for loading, and the loading flow rate is 2 mL / min; The resting time is 12 hours; then the eluent is 30% ethanol aqueous solution for elution; the amount of eluent is 120mL; the elution flow rate is 2mL / min. Collect the entire eluate in a weighed clean glass.
