Embodiment

[0044] A method for extracting salidroside, comprising the following steps:

[0045] A, picking fresh Rhodiola rosea, removing individual disease and insect pests, and drying;

[0046] B, the dry Rhodiola is ground into powder, the Rhodiola after grinding is soaked, and percolated to obtain the percolate;

[0047] C. Take the supernatant of the leachate after standing still, and use resin adsorption to remove polysaccharides and proteins; wash the sample with purified water until it is colorless, and then use the eluent 4-8% ethanol aqueous solution, 14-18% ethanol water solution, 24-28% ethanol water solution, 34-38% ethanol water solution and 44-48% ethanol water solution for gradient elution, the pH value of the eluent is 6.4-6.6, collect each gradient eluent And concentrated to obtain five groups of salidroside crude products;

[0048] D. Separating and purifying impurities from the crude salidroside in each group to obtain high-purity salidroside.

[0049] Wherein, whe...

Abstract

The invention discloses an extraction method of salidroside. The extraction method comprises the following steps: A, picking fresh rhodiola rosea, removing the fresh rhodiola rosea with diseases and pests, and drying; B, grinding the dry rhodiola rosea into powder, soaking the ground rhodiola rosea, performing percolation to obtain a percolation solution; C, collecting supernatant after the percolation solution stands, and removing polysaccharides and proteins by virtue of the adsorption of resin; after a sample is loaded, flushing by using pure water until the sample is colorless, then performing gradient elution by using an elution solution of 4 to 8 percent of ethanol aqueous solution, 14 to 18 percent of ethanol aqueous solution, 24 to 28 percent of ethanol aqueous solution, 34 to 38percent of ethanol aqueous solution and 44 to 48 percent of ethanol aqueous solution, wherein the pH value of the elution solution is 6.4 to 6.6, separately collecting each gradient elution solution,concentrating to obtain five groups of salidroside crude products; and D, separating impurities and purifying each group of salidroside crude product to obtain high-purity salidroside. By adopting themethod, the salidroside is extracted, the extraction rate is high, and the purity of the extracted salidroside is high.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicines, in particular to a method for extracting salidroside. Background technique [0002] Rhodiola is a perennial herbaceous plant, 10-20 cm high, with strong, conical, fleshy, brown-yellow roots, with many fibrous roots at the root neck, short, thick, cylindrical rhizomes, and most imbricate scales The leaves grow in the alpine and pollution-free areas at an altitude of 1800-2500 meters, and their growth environment is harsh, so they have strong vitality and special adaptability. It can be used as medicine, can invigorate qi and clear the lungs, improve intelligence and nourish the heart, and is a traditional Chinese medicine with a wide range of effects. It also has a great cosmetic effect and can be used as a skin care product or edible. [0003] Salidroside is the main active ingredient of Rhodiola rosea. In recent years, with the improvement of people's living standards an...
