Abstract

The invention relates to a method for extracting chlorogenic acid from Jerusalem artichoke. The method is that, after the water of the jerusalem artichoke is removed and the enzyme is activated, the raw material is extracted by using solvent under the action of ultrasonic wave or microwave, chlorogenic acid extract liquid is obtained after solid-liquid separation, and finally pure chlorogenic acid is obtained after adsorption separation through polyamide or macroporous resin, elution and refining. The solvent can be water, organic solvent or mixed solution of organic solvent and water. Through the fixation treatment of the Jerusalem artichoke and the extraction by using the organic solvent or water under the assistance of the ultrasonic wave or the microwave, the yield of chlorogenic acid is improved and the extraction time is reduced. By using Jerusalem artichoke to extract pure chlorogenic acid, the source of raw material for preparing chlorogenic acid is widened, more valuable development and utilization of the Jerusalem artichoke are realized, and the economic benefit and the social benefit are better.

Description

technical field

[0001] The invention relates to a method for extracting chlorogenic acid from Jerusalem artichoke. Polyamide or macroporous resin is used to separate and purify the extract, and combined with water or organic solvent recrystallization method to refine chlorogenic acid, which belongs to the field of separation and purification of biochemical products. Background technique

[0002] Jerusalem artichoke, commonly known as Jerusalem artichoke, Latin name Helianthus tuberosus L., belongs to the Asteraceae sunflower genus annual herb, native to North America. It was introduced to Europe in the 17th century. It is also cultivated in most provinces and regions of our country. Jerusalem artichoke is mainly propagated by tubers, and the leaves are oval or oblong. The small protrusions on the surface of the blade are evenly distributed, and the back side is relatively smooth. The stem height of Jerusalem artichoke is generally about 2m, and the height can reach more t...
