Problems solved by technology

[0003] The traditional extraction method of sunflower flavonoids is extracted with ethanol (or methanol)-water mixed solution. During the extraction process, it is necessary to add ether to remove lipid components, add pectinase to remove pectin, and add alcohol to remove sugar and protein; the operation is cumbersome. There are many types of solvents, many types and high content of impurities in the extract, and low impurity removal efficiency
In addition, there is no extraction method for sunflower disc flavonoid glycosides

Abstract

The invention provides a method of extracting sunflower head flavonoid glycosides. The method includes the steps of (1) pretreating a raw material; (2) carrying out primary extraction and separation;(3) carrying out secondary extraction and separation; (4) filtering to remove precipitate; (5) preparing extract; (6) acquiring total flavonoid glycosides. The raw material herein has a rich source, low cost and good accessibility; the method is simple; processing cost is low, and yield is high; no toxic solvents are used in the method, so that no environmental pollution is caused; the method herein has the advantages of good economy and safety, good environmental friendliness, and good convenience of industrial production.

Description

technical field [0001] The invention belongs to the technical field of phytochemical extraction, and in particular relates to a method for extracting flavonoid glycosides from sunflower disc. Background technique [0002] Flavonoid glycosides are widely found in various plants in nature, and they are composed of flavonoids and sugars. Its basic structure is that two aromatic rings are connected to each other through three carbons to form a basic mother nucleus, and the mother nucleus is combined with a sugar group to form a flavone. [0003] The traditional extraction method of sunflower flavonoids is extracted with ethanol (or methanol)-water mixed solution. During the extraction process, it is necessary to add ether to remove lipid components, add pectinase to remove pectin, and add alcohol to remove sugar and protein. There are many types of solvents, and there are many types and high content of impurities in the extract, and the removal efficiency is low. In addition, ...
