Abstract

The invention belongs to the technical field of extraction and purification of effective components of traditional Chinese medicines, and particularly discloses a method for extracting and recycling acanthopanax total flavonoids by using a deep eutectic solvent. The method comprises the following steps: by taking powder of acanthopanax roots as a raw material, adding a deep eutectic solvent with a certain water content, extracting acanthopanax total flavonoids under an ultrasonic-assisted condition, and enriching and recovering flavonoid compounds in an extracting solution by using macroporous resin, and meanwhile, after the water in the obtained eutectic recovery liquid is evaporated, extracting the acanthopanax total flavonoids again, wherein the acanthopanax total flavonoids can be repeatedly utilized for at least three times. The invention develops a novel process technology for extracting and enriching the acanthopanax total flavonoid compounds from the acanthopanax roots and stems by combining the eutectic solvent with the macroporous resin, the recycling of the eutectic solvent is realized, and the purposes of greenness, high efficiency and repeatable extraction are achieved. Compared with a traditional extraction method, the method has the advantages of no use of an organic solvent, simplicity and convenience in operation, time saving, safety, low cost and the like, and industrial production can be realized.

Description

technical field [0001] The invention belongs to the technical field of extracting and purifying effective components of traditional Chinese medicine, and relates to a method for extracting and recovering total flavonoids of Acanthopanax senticosus with a deep eutectic solvent, in particular to a new type of ultrasonic-assisted deep eutectic solvent combined with macroporous adsorption resin from the rhizome of Acanthopanax senticosus A method for extracting and purifying total flavonoids from Acanthopanax. Background technique [0002] Acanthopanax is a shrub belonging to the Araliaceae family. It is widely distributed in Russia, South Korea, Japan and Northeast China in Asia. Its roots, stems, leaves, flowers and fruits all have pharmacological activity and are often used as various functional preparations. Acanthopanax contains a large number of biologically active ingredients, such as eleutheroside, flavonoids, polysaccharides and polyphenols, etc., which are the materia...
