Abstract

The invention discloses an extraction method for salidroside. The extraction method comprises the following steps: obtaining a crushed rhodiola rosea material, and carrying out enzymolysis so as to obtain an enzymatic hydrolysate; adding the enzymatic hydrolysate into an extraction tank in batches so as to obtain a crude rhodiola rosea extract; and purifying the crude rhodiola rosea extract so asto obtain the salidroside; wherein the treatment method for each batch of the enzymatic hydrolysate comprises the following steps: adding water, and carrying out stirring at 35-45 DEG C; adding waterinto a system, and carrying out heating to 55-65 DEG C; adding water into the system, carrying out heating to 75-85 DEG C, and carrying out stirring; adding water into the system, and carrying out stirring; reducing the temperature of the system to 55-65 DEG C so as to obtain filtering residues and a primary extracting solution; and washing the filtering residues of the system with water, carryingout filtering so as to obtain a secondary extracting solution, and combining the primary extracting solution and the secondary extracting solution so as to obtain the crude rhodiola rosea extract. According to the invention, the rhodiola rosea is firstly subjected to enzymolysis after being crushed, and the enzymatic hydrolysate is subjected to extraction in batches at different temperatures, sothe transfer rate of the salidroside can be effectively increased, and the extraction rate of the salidroside is increased.

Description

technical field [0001] The invention relates to the technical field of salidroside extraction. More specifically, the present invention relates to a method for extracting salidroside. Background technique [0002] Rhodiola rosea is a perennial herb. Rhodiola rosea generally grows in mountain streamstones or bushes above 3,500 meters above sea level. Its growth environment is harsh, so it has very tenacious vitality and special adaptability. As a medicinal material, Rhodiola rosea can invigorate qi, clear the lungs, improve intelligence and nourish the heart. It has a wide range of effects, and it also has a great beauty effect. It can be used as a skin care product and can also be eaten. [0003] Salidroside is the main component of Rhodiola rosea. Salidroside has good application prospects in the treatment of cardiovascular and cerebrovascular diseases, and it also has anti-hypoxia, anti-fatigue, anti-radiation, and anti-cold effects. At present, there are many methods fo...
