Zusammenfassung:The present invention belongs to the field of natural organic chemistry, and relates to an extraction and separation method for anthocyanidin derived from vaccinium vitis idaea. According to the method, tea polyphenol is adopted as an antioxidant, extraction is performed under an acid condition, impurity removing is performed with a flocculant, and purification is performed by using a macroporous adsorption resin so as to obtain the high-purity anthocyanidin product. The industrial method of the present invention has the following advantages that: 1, the water is adopted as the extraction solvent under the acid condition so as to substantially reduce the production cost compared with the conventional extraction using ethanol; 2, the tea polyphenol is added as the antioxidant during the extraction process so as to effectively reduce the anthocyanidin loss; and 3, the flocculant is used to precipitate the impurities in the extraction liquid so as to easily improve the purity of the anthocyanidin product. The prepared anthocyanidin of the present invention can be widely used in the fields of health food, cosmetics, and the like.
