Problems solved by technology

However, at present, the development and utilization of Sorbus arvensis is low, and the value of anthocyanins has not been fully developed. The polyphenols are mainly concentrated in the aspects of lowering blood fat, blood sugar, and anti-oxidation. The process of rowan anthocyanins has not been reported

Abstract

The invention discloses a method for extracting anthocyanins from berry fruits. The method comprises the following steps: (1) beating the berry fruits into pulp, adding an ethanol aqueous solution andextracting; purifying the extract liquid by macroporous resin, evaporating to recover a solvent by rotary evaporation, concentrating the extract liquid, and freeze-drying in vacuum to obtain crude anthocyanin extracts; and (2) separating an anthocyanin crude extract solution by simulated moving bed chromatography, to obtain the anthocyanin extracts. The anthocyanin extracts in the berry fruits are separated and purified by macroporous resin and the simulated moving bed, the anthocyanin extracts with fewer impurities are separated out, and then the anthocyanin extracts for resisting senility are prepared. The method realizes industrialized production of the anthocyanin extracts so as to improve the production efficiency of the anthocyanins. The anthocyanins can be used alone or combined infood or medicines, and are made into any dosage form of health care products or medicines, and anthocyanins of aronia melanocarpa elliot, mulberry, grapes and the like have the function of delaying senility.

Description

technical field [0001] The invention relates to a method for simulating a moving bed to separate anthocyanins with anti-aging effects. Background technique [0002] Anthocyanins belong to the flavonoids of plant polyphenols, which are secondary metabolites of plants. Its structure is composed of anthocyanins with a C6-C3-C6 skeleton structure combined with glycosides such as glucose and galactose through glycosidic bonds. There are 20 kinds of anthocyanins known in nature, and food-derived anthocyanins mainly have six forms, most of which exist in the form of glucose esterification. Anthocyanins are esterified with glucose, galactose, arabinose, xylose, rhamnose, etc. to form anthocyanins; Diacids, malic acid, succinic acid, and acetic acid, etc. undergo acylation reactions to form acylated forms of anthocyanins. Anthocyanins contain multiple phenolic hydroxyl groups and have strong antioxidant activity. As free radical scavengers and antioxidant active substances, they ar...
