Abstract

The invention belongs to the technical field of lycium barbarum polysaccharide extraction, and provides an ultrasonic extraction method of lycium barbarum polysaccharide. The method comprises the following steps of: accurately weighing 5g of lycium barbarum dry powder, placing in a conical flask and adding 150mL of distilled water; performing ultrasonic extraction twice, filtering, combining the filtrates, precipitating with 95% ethanol and standing for 24 hours before suction filtration; washing the obtained solid matter sequentially with 95% ethanol, absolute ethyl alcohol and acetone; and performing vacuum drying at 50 DEG C to obtain the coarse powder of solid matter lycium barbarum polysaccharide, wherein the best technological conditions of the ultrasonic extraction of lycium barbarum polysaccharide are as follows: the ultrasonic material-liquid ratio is 1:30, the power is 90W, the time is 30min, and the extraction is conducted twice; and moreover, the extraction technology is simple, the usage amount of the extraction solvent is small, the yield is high, the cost is low, and a great value in popularization and application is realized.

Description

technical field [0001] The invention belongs to the technical field of wolfberry polysaccharide extraction, in particular to a method for ultrasonically extracting wolfberry polysaccharide. Background technique [0002] Lycium barbarum is a plant of the genus Lycium barbarum in the family Solanaceae, and its fruit, Lycium barbarum, is a traditional precious Chinese medicinal material in my country, known as "Red Treasure". Lycium barbarum is rich in plant polysaccharides, protein, vitamins and other nutrients. It has the functions of protecting liver and lungs, nourishing kidneys and improving eyesight, nourishing qi and promoting essence, eliminating fatigue, strengthening muscles and bones, anti-aging, lowering blood sugar, lowering blood lipids, and enhancing immunity, etc. Pharmacological effects have always been highly valued by Chinese and foreign medical and dietary experts. Lycium barbarum polysaccharide is an important biological regulator, which can regulate the b...
