Embodiment Construction

[0007] This specific embodiment adopts the following technical scheme: its preparation method is: 1), raw material pretreatment: dry rhodiola rosea shredder is pulverized, crosses 30 mesh sieves; 2), extraction: the raw material that pulverizes is passed through conveyer belt Send it into an extraction tank with temperature control and stirring for extraction, and collect the extract. The extraction temperature is 60-100°C. The extraction solvent used is water, ethanol or methanol, and the ratio of solid to liquid (m / v ratio) is 1:5 ~1:10; 3), Concentration: Concentrate the extract to a small volume with a single-effect concentrator or a high-effect concentrator or a falling film concentrator, and the specific gravity of the concentrated solution is between 1.05 and 1.1; 4), Filtration: first Centrifuge with a bag-type centrifuge, and then filter with a membrane device; the pore size of the filter membrane used is 0.2-0.45 μm; 5) Adsorption: The filtrate is adsorbed with a macr...

Description

Technical field: [0001] The invention relates to the field of natural medicines, in particular to a medium-pressure preparation method of Rosevet monomer. Background technique: [0002] Roseville is an extract from the root of Rhodiola rosea L. in the sedum family Rhodiola genus. Rhodiola rosea, perennial herb, 10-20 cm high. 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. Harvest from July to September. It has the following functions: 1. Enhance immune function; 2. Feeling of depression; 3. Protect cardiovascular function; 4. Effective antioxidant; 5. Improve human body function; 6. Ant...
