Problems solved by technology

[0005] In short, there have been many reports on the extraction and purification of flavonoids, but a method with low energy consumption, short time, clean process, simple process and good separation effect has not been found so far. Therefore, a new and efficient flavonoid extraction and purification technology has been developed. very necessary

Abstract

The invention discloses a method for extracting opisthopapus taihangensis total flavonoid from opisthopapus taihangensis. The method comprises the following steps: extracting flavonoid from the opisthopapus taihangensis by adopting a high-pressure homogenization method to obtain a crude extracting solution; then adsorbing the flavonoid from the crude extracting solution by utilizing a prepared magnetic molecularly imprinted polymer, so as to simply and efficiently realize separation of the flavonoid. When the method is used for extracting the opisthopapus taihangensis flavonoid from the opisthopapus taihangensis, the method has the advantages of environment friendliness, high extraction rate, good product quality, short production period, convenience for operation and relatively low cost and is suitable for industrial production.

Description

technical field [0001] The invention relates to an extraction process, in particular to a method for extracting total flavonoids of chrysanthemum chrysanthemum from chrysanthemum chrysanthemum. Background technique [0002] Flavonoids have many effects. It is a strong antioxidant that can effectively remove oxygen free radicals in the body. For example, anthocyanins can inhibit the full-stage overflow of oily peroxides. This ability to prevent oxidation is a vitamin More than 10 times that of E, this antioxidant effect can prevent cell degeneration and aging, and can also prevent the occurrence of cancer. Flavonoids can improve blood circulation and lower cholesterol. The flavonoids in Tianguo also contain a PAF anticoagulant factor. These effects greatly reduce the incidence of cardiovascular and cerebrovascular diseases, and can also improve the symptoms of cardiovascular and cerebrovascular diseases. The sky fruit from the South Pacific island country is rich in 33 flavo...
