Puerarin extraction process

Abstract

The invention discloses a puerarin extraction process, relating to extraction of effective components in Chinese herbal medicine plants and belonging to the field of extraction processes. The puerarin extraction process is characterized by comprising the following steps: taking kudzu root, pulverizing at the low temperature of -4-0 DEG C, passing through a 30-100-mesh screen, adding distilled water which is 1-7 times by weight of kudzu root, immersing at room temperature for 5-8 hours, stirring with a stirrer to obtain a kudzu root slurry, adding an enzyme preparation to perform enzymolysis reaction while performing low-intensity ultrasonic treatment, carrying out solid-liquid separation and collecting the filtrate to obtain the kudzu root extract concentrated solution. The technique for extracting effective components of kudzu root has the advantages of high production efficiency, low requirements for equipment, high controllability, high operability and low energy consumption, is suitable for large-scale production of the kudzu root product, is beneficial to overall development and utilization of kudzu root resources, and has obvious economic benefit and social benefit. The kudzu root beverage prepared by the technique has the advantages of high nutrient content and good and diversified tastes, is convenient to drink, and is convenient for transportation and storage.

Description

technical field [0001] The invention relates to an extraction of effective components of Chinese herbal medicine plants, which belongs to the field of extraction technology, in particular to a puerarin extraction technology. Background technique [0002] Pueraria Lobata (Willd.) Ohwi is the dried root of Pueraria Lobata (Willd.) Ohwi, a leguminous plant. It is a commonly used natural plant for both medicine and food. It tastes sweet and cool, and is often used for soup; it contains about 12 % flavonoids, including more than 10 kinds of daidzein, daidzein, puerarin, etc., and also contain carrotin, amino acids, coumarins, etc., which have the functions of expanding blood vessels, improving blood circulation, lowering fat and blood sugar, anti-oxidation and Various functions such as scavenging free radicals. [0003] Puerarin flavonoids and puerarin extracted from pueraria root have been widely used in health food, biopharmaceutical and other fields in the United States. In ...

Problems solved by technology

The extraction of puerarin is also more and more paid attention to by people. Traditionally, the utilization of puerarin is generally directly edible or medicinal, and its beneficial components such as puerarin cannot be effectively utilized, and it is inconvenient to eat, and the taste is single; The extraction methods are generally water extraction and alcohol precipitation method, n-butanol-water extraction method, alumina decolorization method, polyacrylamide chromatography, glacial acetic acid crystallization method and other extraction and purification methods, but these technologies have limited extraction efficiency. Incomplete extraction, many links, large use of flammable and toxic organic solvents, easy to cause environmental pollution and health damage to operators, and difficult to remove harmful impurities in the product, high production cost, long cycle, low puerarin content, etc. , the effect is not ideal when applied to the processing of puerarin products
