The invention relates to the technology field of extraction and separation methods of effective ingredients from medicinal plants, particularly to a method for extracting high-purity neohesperidin. The prior art has the disadvantages of high requirements for raw materials, long production period, and high cost. The inventive method comprises the steps of: extracting bitter orange, immature bitter orange and sour orange with a solvent under reflux to obtain crude extract, concentrating to obtain concentrate, performing liquid extraction and salting out to obtain crude neohesperidin, and recrystallizing to obtain neohesperidin product. Compared with the prior art, the inventive method has the advantages of large raw materials selecting range, simple operation, low cost, high yield, high purity, environmental friendliness, and applicability to large scale production.
Description
A method for extracting high-purity neohesperidin Technical field: The invention relates to the technical field of extraction and separation methods for active ingredients in medicinal plants, in particular to a method for extracting high-purity neohesperidin. Background technique: Neohesperidin belongs to flavonoids, and is usually distributed in sour orange, citrus aurantium, citrus aurantium, and immature pomelo, with the highest content in citrus aurantium. Pharmacological studies have shown that the flavonoids in Fructus Aurantium and Fructus Aurantii have inhibitory effects on the non-physiological contraction of smooth muscle in rats, and can resist the spasmodic contraction caused by barium chloride and acetylcholine, and also have antibacterial and anti-inflammatory effects. In addition, neohesperidin is also an important raw material for the synthesis of sweetener neohesperidin dihydrochalcone. Neohesperidin dihydrochalcone is an important sweetener, its sweetne...
