Abstract

The invention relates to a method for separating and purifying hyperoside and isoquercitroside from aurea helianthus, belonging to the field of extraction and separation of natural compounds. The method comprises the following steps: heating, refluxing, and extracting flavones in the aurea helianthus; under alkaline condition, forming stable complex precipitate by zinc salt with flavonoids exceptthe hyperoside and isoquercitroside in the aurea helianthus; centrifuging to remove the complex precipitate; and concentrating supernatant, thus obtaining high-purity hyperoside and isoquercitroside.The method provided by the invention can be used for rapidly, efficiently and safely separating and purifying the hyperoside and isoquercitroside from the aurea helianthus and is beneficial to realization of industrial production of the hyperoside and isoquercitroside.

Description

technical field

[0001] The invention relates to a method for separating and purifying hyperin and isoquercitrin from sunflower. Specifically, starting from the extract of goldenflower sunflower, using the weak complexing ability of hyperin and isoquercitrin with zinc salts, and the strong complexing ability of other flavonoids with zinc salts, the removal of goldenflower sunflower Other flavonoids in the extraction solution, and develop a rapid, efficient and safe method for separating and purifying hyperin and isoquercitrin from annulus annuus. It belongs to the field of natural compound extraction and separation. Background technique

[0002] Hyperoside is also known as quercetin-3-O-β-D-galactopyranoside, isoquercitrin is also known as quercetin-3-O-β-D-glucopyranoside, both It is the glycoside of quercetin. It has the same aglycon and similar polarity. Only the configuration of a hydroxyl group in the sugar moiety is different. The former is galactoside, the latter is ...
