Embodiment

[0027] (1) Weighing 200kg of dried Rhodiola rosea, the content of rosavirin and salidroside is 1.38%, and the content of salidroside is 0.92%, and it is crushed to 20 meshes; the mass ratio is 60% ethanol aqueous solution to extract and reflux three times, and the ratio of extraction solvent to material 8:1; 6:1; 4:1; the extraction time is 2 hours;

[0028] (3) Mix and concentrate the extracts. The vacuum degree is that the vacuum concentration temperature is below 60°C, the vacuum degree is not less than 0.08pma, and the concentration time is not more than 2 hours. Concentrate to an alcohol-free state with a density of 1.05-1.10;

[0029] (4) The concentrate is centrifuged with a filter cloth of 500 mesh;

[0030] (5) Pack the processed D101 macroporous resin into a 200L column. The centrifugate has an adsorption speed of 1.0-1.5bv / h and a washing speed of 2-3 bv / h. The concentration is 50-70%, and the elution rate is 1.0-1.2bv / h. Collect the eluate and concentrate until i...

Abstract

The invention discloses a method for preparing rosavin from rose rhodiola rosea. The method comprises the following steps: pretreating raw materials; extracting; filtering; passing macroporous resin primarily; concentrating; passing resin again; separating membrane; spraying and drying, and the like. Compared with other methods, two times of column chromatography methods and the membrane method are adopted, so that the method disclosed by the invention is more suitable for industrial production. The product obtained by the method is high in safety, purity, quality and yield.

Description

technical field [0001] The present invention relates to a health care product, a method for preparing rosacea from Rhodiola rosea in the field of medicine, and specifically relates to a method of crushing and extracting, enriching and purifying through macroporous resin, resin purification again, and membrane separation to obtain The method of Netservi products. Background technique [0002] Rhodiola rosea is a perennial herb with a height of 10-20 cm. The roots are thick, conical, fleshy, brownish yellow, with many fibrous roots at the root neck. Rhizome short, stout, terete, covered by numerous imbricate scale-like leaves. Several flower stems are extracted from the leaf axils at the top of the stem. The upper and lower parts of the flower stems have fleshy leaves, the leaves are elliptic, with serrated edges, sharp apex, cuneate base, almost sessile. Cymes terminal, flowers red. Rhodiola rosea is a well-known traditional medicinal plant in China and Eastern European c...
