Abstract

The invention discloses an extraction method of galinsoga parviflora flavone. The extraction method comprises the following steps that an ethanol solution and a surfactant are sequentially added into galinsoga parviflora powder, and extracting is carried out in a water bath at 75-80 DEG C for 1-1.5 hours; and in the extraction process, the volume fraction of ethanol in the ethanol solution is 40%, the addition amount of the surfactant is 2-5g / L, and the liquid-material ratio of the ethanol solution to the achyranthes bidentata inulin in the extraction process is 30-50mL / g. The extraction method of the galinsoga parviflora flavone has the beneficial effects that the flavone in the galinsoga parviflora is extracted through the surfactant and the ethanol solution, the operation is simple and convenient, and the flavone extraction rate is high.

Description

technical field [0001] The invention relates to the technical field of flavone extraction. More specifically, the present invention relates to a method for extracting chrysanthemum flavonoids. Background technique [0002] Galinsoga parviflora Gav. (Galinsoga parviflora Gav.) is an annual herbaceous plant of the family Asteraceae. It is also known as sunflower, pepper grass, and pearl grass. , Tibet and other provinces (regions) are generally distributed. Achyranthes chrysanthemum is tenacious and can grow in various environments. [0003] Flavonoids are a large class of compounds that exist in nature. They are secondary metabolites produced by plants during the long-term natural selection process and widely exist in nature. In 1814, a European scientist discovered the first flavonoids—— ——Chrysin, as of 2000, as many as 8,000 flavonoids have been found in the world. They exist in various plants, and they have been found in plants such as Rutaceae, Labiatae and Compositae...
