Abstract

The invention provides a method for extracting camellia polyphenol. The method comprises the following extraction steps: (1), preparing camellia powder: freezing, crushing and sieving camellia; (2), performing preparation of a leaching solution: adding camellia powder into the extracting solution, performing ultrasonic extraction, preparing the extracting solution, and preparing the extracting solution from acetone, bio-enzyme, glacial acetic acid and water; (3), performing filtering: adding an adsorbent into the extract liquid prepared in the step (2), performing oscillating, adsorbing and filtering to obtain polyphenol filtrate; (4), performing extraction: extracting the polyphenol filtrate obtained in the step (3) by using saturated n-butyl alcohol and ethyl acetate respectively to prepare a camellia polyphenol crude extract; and (5), performing concentrating and drying: concentrating and drying the camellia polyphenol crude extract prepared in the step (4) to obtain the camellia polyphenol. According to the extraction method, less organic solvent is used, the operation is simple, the extraction rate of the camellia polyphenol is higher than 19%, and the purity of the camellia polyphenol is higher than 95%.

Description

technical field [0001] The invention relates to the field of polyphenol extraction, in particular to a method for extracting camellia polyphenols. Background technique [0002] Polyphenols are one of the important components of natural medicines with various functional activities, which may have a good effect on the prevention of diseases. For example, polyphenols can prevent chronic diseases such as cardiovascular and cerebrovascular diseases, have a strong ability to scavenge free radicals, reduce oxidation, reduce the chance of tumor formation and reduce the risk of cancer. For example, CN201710612581.8 preparation method of tea polyphenols in Southwest Camellia, the method uses dried Southwest Camellia as raw material, reflux extraction with 50-80% acetone aqueous solution as solvent, the extract is concentrated and dried, then dissolved in water, filtered , after the filtrate is adsorbed by DM130 macroporous resin, the impurities are eluted with distilled water, and th...
