Abstract

The invention discloses an extraction method of alpinia galanga rhizome flavonoids. The extraction method of the alpinia galanga rhizome flavonoids includes the steps of: alpinia galanga rhizome preprocessing, microwave extraction, enzymolysis treatment, supercritical CO2 extraction, vacuum concentration, and vacuum freeze-drying; and by adopting the extraction method, the alpinia galanga rhizomeflavonoids are obtained. According to the extraction method of the alpinia galanga rhizome flavonoids, ways of microwaves, enzymolysis and supercritical CO2 extraction are creatively adopted to extract the alpinia galanga rhizome flavonoids, after microwave treatment, enzymolysis is carried out, therefore, the flavonoids are better dissolved out, the extraction rate of the flavonoids is increased,and waste of resources is reduced; and after supercritical CO2 extraction, no organic solvent residues exist, therefore, products are ensured to be 100% pure natural, and the flavonoids with high purity are obtained.

Description

technical field [0001] The invention belongs to the technical field of plant extraction, and in particular relates to a method for extracting galangal flavonoids. Background technique [0002] Southern ginger (Alpiniagalanga (Linn.) Willd.), also known as reed ginger, red cardamom, and galanga, is a plant of the Zingiberaceae family, a perennial herb of the Zingiberaceae family, widely distributed in tropical Asia. In Chaozhou cuisine, galangal is an essential ingredient in brine bowls. It can even be said that the presence or absence of galangal is the main difference between Chaozhou brine and brine from other places. The fruits and rhizomes of galangal are used for medicinal purposes. In recent years, studies have found that the rhizomes contain a variety of aromatic oils, flavonoids, minerals, sugars and other substances, which have multiple properties such as stimulating, activating and anti-free radicals for the skin. [0003] Meridian distribution of nature and flavo...
