Abstract

The invention discloses a process for extracting salidroside with the assistance of ultrasonic waves. According to the process, the extraction of the salidroside in rhodiola crenulata can be assisted by adopting the ultrasonic waves; the rhodiola crenulata is extracted for four times by adopting four solvents; when the rhodiola crenulata is in a powder state, active ingredients are extracted more easily; the rhodiola crenulata is wrapped by adopting a medical non-woven fabric, and the active ingredients are extracted in virtue of the power of the ultrasonic waves, so that the extracting yield of the salidroside is improved; the process is simple in operation, and suitable for massive industrial production. Added citrate synthase can remove polysaccharides from the salidroside, so that the purity of the salidroside is improved, and the purity of the salidroside can reach 98 percent or above.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine extraction, and in particular relates to an ultrasonic-assisted extraction process of salidroside. Background technique [0002] Rhodiola daflora is the tuber of Rhodiola grandiflora, a plant of the Crassulaceae family, mainly produced in Tibet, northwestern Yunnan, and western Sichuan. Born in hillside grasslands, bushes, and rock crevices at an altitude of 2800-5600 meters. The functions and indications of Rhodiola daflora include: improving sleep, promoting blood circulation, anti-brain hypoxia, anti-fatigue, promoting blood circulation and stopping bleeding, clearing lung and relieving cough, reducing stasis and swelling, antipyretic and antipyretic, nourishing vitality, etc. Rhodiola daflora oral liquid is made by extracting the active ingredients of Rhodiola rosea, which is convenient to carry and take, and has high bioavailability. The main active ingredient of Rhodiola grandif...
