Embodiment 1

[0045] Embodiment 1 The preparation of seabuckthorn total flavonoids extract of the present invention

[0046] Seabuckthorn fruit juice was freeze-dried to obtain seabuckthorn fruit powder, and ultrasonically extracted with ethanol for 2.5 hours, the ultrasonic power was 100W, the extraction temperature was 65°C, the volume fraction of ethanol was 55%, the ratio of solid to liquid was 5mL / g, and the number of extractions was 3 times. solution, after removing ethanol, dissolved in distilled water, and dynamically adsorbed on D101 macroporous adsorption resin column, the sample volume was 4BV, adsorbed at room temperature for 1h, eluted with 60-80% ethanol, analyzed, collected eluent, and then The seabuckthorn flavonoid extract with a purity of more than 90% is obtained.

Abstract

The invention provides a fructus hippophae flavone extract. The total flavone content in the extract is 80%w / w to 90%w / w. The flavone content (or purity) in the fructus hippophae flavone extract provided by the invention is obviously higher than that of a commercial specification; an advantage is provided for the further research of fructus hippophae flavone; meanwhile, an extract raw material which is higher in the purity is also provided for a healthcare product or a medicine in which the fructus hippophae flavone is used as an active component.

Description

technical field [0001] The invention relates to a high-purity seabuckthorn flavonoid extract and a preparation method thereof. Background technique [0002] Seabuckthorn is the fruit of the perennial shrub or tree plant Hippophae rhamnoides Linn. Seabuckthorn is a medicinal and edible plant. The roots, stems, leaves, flowers, and fruits of seabuckthorn, especially the fruit of seabuckthorn, are rich in nutrients and biologically active substances, and can be widely used in many fields of the national economy such as food, medicine, light industry, aerospace, agriculture, animal husbandry and fishery.
