Embodiment 1
[0037] (1) Preparation of crude sugar from Lycium barbarum leaf buds: Freshly picked Lycium barbarum leaf buds were dried at 40°C, crushed to a fineness of 60 mesh by a pulverizer, and added ultrapure water according to a material-to-liquid (Kg / L) ratio of 1:20, Using pilot extraction equipment (TS-NS-300 multi-functional extraction and concentrator, Shanghai Shunyi Experimental Equipment Co., Ltd.) to stir and extract at 40°C for 8h. The extract obtained after extraction is filtered and then concentrated to 1 / 10 of the volume before concentration at a negative pressure of 0.04MPa and a concentration temperature of 50°C, and then adding ethanol by volume until the content ratio of ethanol is 70%. After standing overnight, filter, retain the filter residue, evenly spread the filter residue in a stainless steel freeze-drying tray, put it into a freeze dryer to dry, and the moisture content of the product is ≤5%. The obtained powder is the crude polysaccharide of Lycium barbarum ...
Embodiment 2
[0046] (1) Preparation of crude sugar from Lycium barbarum leaf buds: Freshly picked Lycium barbarum leaf buds were dried at 50°C, crushed to a fineness of 80 meshes by a pulverizer, added ultrapure water at a material-to-liquid ratio of 1:25, and extracted using pilot-scale extraction equipment ( TS-NS-300 multifunctional extraction and concentrator (Shanghai Shunyi Experimental Equipment Co., Ltd.) was stirred and extracted at 50°C for 9h. The extract obtained after extraction is filtered and then concentrated to 1 / 14 of the volume before concentration under the condition of negative pressure 0.05MPa and concentration temperature 55°C, and then adding ethanol by volume until the content ratio of ethanol is 73%. After standing overnight, filter, retain the filter residue, evenly spread the filter residue in a stainless steel freeze-drying tray, put it into a freeze dryer to dry, and the moisture content of the product is ≤5%. The obtained powder is the crude polysaccharide of...
Embodiment 3
[0055] (1) Preparation of crude sugar from Lycium barbarum leaf buds: Freshly picked Lycium barbarum leaf buds were dried at 60°C, crushed to a fineness of 100 mesh by a pulverizer, added ultrapure water at a material-to-liquid ratio of 1:30, and extracted using pilot-scale extraction equipment ( TS-NS-300 multifunctional extraction and concentrator (Shanghai Shunyi Experimental Equipment Co., Ltd.) was stirred and extracted at 60°C for 10h. The extract obtained after extraction is filtered and then concentrated to 1 / 16 of the volume before concentration under the condition of negative pressure 0.06MPa and concentration temperature 60°C, and then adding ethanol by volume ratio until the content ratio of ethanol is 76%. After standing overnight, filter, retain the filter residue, evenly spread the filter residue in a stainless steel freeze-drying tray, put it into a freeze dryer to dry, and the moisture content of the product is ≤5%. The obtained powder is the crude polysacchar...
