Abstract

A method of extracting buckwheat flavone from buckwheat hull includes: shatter sweet buckwheat hull or tartary buckwheat hull raw material, formulate extracting solvent of 0.1 mol per liter sodium carbonate, use ultrasonic to extract, use kieselguhr filter for filtration, deposit, centrifuge, washing, and dry craft steps. By substantive laboratory studies and test, the heavy metal content, flavacin B1, pesticide residue, total bacterial count, mold and microzyme number, coliform group, salmonella and Staphylococcus aureus of buckwheat flavone produced by this method all meet regulation of commerce department medicinal plant and preparation trade green industry stand ard.

Description

technical field [0001] The invention belongs to the technical field of preparation of non-alcoholic beverages, and in particular relates to a method for extracting buckwheat flavonoids from sweet buckwheat or tartary buckwheat husks. Background technique [0002] Buckwheat (Fagopyrum esculentum) is a dicotyledonous plant belonging to the genus Fagopyrum of the Polygonaceae family, and has two cultivars, sweet buckwheat and tartary buckwheat. The main component of flavonoids contained in buckwheat is rutin. Rutin, also known as vitamin P, is also called rutin, which can promote the accumulation of vitamin C in the body, enhance the immune function of the human body, maintain the normal activity of capillaries, and reduce vascular circulation. Permeability, promoting cell proliferation and preventing blood cell aggregation, as well as anti-inflammatory, anti-allergic, diuretic, antispasmodic, antitussive, hypoglycemic, hypolipidemic, etc. Clinically, it is often used to preve...
