Abstract

The invention discloses a method for extracting salidroside, comprising the following steps: obtaining rhodiola pulverized material and performing enzymatic hydrolysis to obtain an enzymatic hydrolysis solution; adding the enzymatic hydrolysis solution to an extraction tank in batches to obtain a crude rhodiola rosea Extract, wherein, the treatment method of each batch of enzymatic hydrolysis solution is: adding water and stirring at 35-45 ° C; adding water to the system and heating up to 55-65 ° C; adding water to the system and heating to 75 ° C Stir at ~85°C; add water to the system and stir; drop the temperature of the system to 55-65°C to obtain a filter residue and a primary extraction solution; rinse the filter residue with water and filter the system to obtain a secondary extraction solution, which is combined to form a rhizoma Step 5: Purify the crude extract of Rhodiola to obtain salidroside. The invention can effectively improve the transfer rate of salidroside by pulverizing Rhodiola and then perform enzymolysis first, and then place the enzymolyzed solution at different temperatures for batch extraction, thereby improving the extraction rate of salidroside. .

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 is a perennial herb. Rhodiola generally grows in alpine flowstones 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 can tonify Qi, clear the lungs, nourish the mind and nourish the mind. [0003] Salidroside is the main component of Rhodiola rosea. Salidroside has good application prospects in the treatment of cardiovascular and cerebrovascular, and also has anti-hypoxia, anti-fatigue, anti-radiation, anti-cold and other effects. At present, there are many methods for extracting salidroside from Rhodiola, but the existing methods have the defect that the transfer rate of salidroside is low, resulting in a low extraction rate of sali...
