Embodiment Construction

[0013] Below in conjunction with specific embodiment the technical scheme of the present invention is described in further detail

[0014] Extraction test of Oxytropis flavonoids:

[0015] In order to comprehensively investigate the factors affecting the extraction of Oxytropis flavonoids, according to the design principle of Central Composite, the extraction temperature, extraction pressure, extraction time, entrainer concentration, entrainer flow rate and CO 2 The flow rate was taken as the investigation factor, combined with the experience of multiple extractions, several levels were selected for each factor to arrange experiments, the extraction rate of Opinus flavonoids was the response value, and the optimal extraction process was optimized.

Abstract

The invention discloses a preparation method and application of oxytropis glabra DC flavone. The preparation method comprises the following steps: (1), extracting oxytropis glabra DC flavone by supercritical CO2; and (2), preparing sheep feed additive from oxytropis glabra DC flavone. The preparation method has characteristics of less consumption of an organic solvent, stable production process, less pollution, and high extraction rate and purity of oxytropis glabra DC flavone; extracted oxytropis glabra DC flavone can be used for enhancing immunization and oxidation resistance functions of sheep.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and relates to a preparation method and application of Oxytropis flavonoids. Background technique [0002] At present, food safety issues have become the focus of people's attention. Among them, the drug residues, drug resistance and the vertical and horizontal transmission of drug resistance brought about by the long-term abuse of antibiotics have also aroused widespread concern. In view of this, the issue of feed safety has attracted more and more attention. The World Health Organization (WHO) has officially proposed that antibiotics should not be used in areas other than humans. Developed countries in Europe and the United States have banned or restricted the use of antibiotics in feed. There is no doubt that Feed antibiotics are banned irreversible trend. The selection of its substitutes has become a research hotspot in animal nutrition. Some nutritionally active substances such as...
