Extraction method of salvia miltiorrhiza polysaccharide from tanshinol residues

Abstract

The invention provides an extraction method of salvia miltiorrhiza polysaccharide from tanshinol residues. The salvia miltiorrhiza polysaccharide is prepared by performing extracting, suction filtering, concentrating, dialyzing, alcohol precipitating, suction filtering, vacuum drying, content detecting and other process flows to salvia miltiorrhiza residues which are subjected to alcohol extraction in an ultrasonic-assisted complex enzymes method, wherein the polysaccharide yield is 11.46 percent, and the polysaccharide content is over 80 percent. Residues after industrial production of salvia miltiorrhiza alcohol extract are used as materials in the method, sustainable utilization of resources can be realized, the production cost of salvia miltiorrhiza and the treatment cost of industrial waste can be saved, the extraction steps of the salvia miltiorrhiza polysaccharide can be reduced, resources are saved, and efficiency can be improved. According to the extraction method, the salvia miltiorrhiza polysaccharide is extracted by adopting the ultrasonic-assisted complex enzymes method, the adopted papain has good protein removal effect, and extra protein removal process can be saved. The product prepared by the method has high purity, wherein the polysaccharide content is over 80 percent.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of traditional Chinese medicine resources, and relates to secondary resource development of salvia miltiorrhiza waste, in particular to a method for extracting salvia miltiorrhiza polysaccharide from alcohol extraction residue of salvia miltiorrhiza. Background technique [0002] Salvia miltiorrhiza Bunge is a perennial herb belonging to the genus Salvia Linn. of the family Lamiaceae. It is slightly cold in nature, bitter in taste, non-toxic, and has the effects of promoting blood circulation, promoting menstrual flow, dispelling blood stasis and relieving pain, clearing the heart and calming the nerves. Pharmacological studies have shown that Salvia miltiorrhiza not only has a very significant effect on the cardiovascular system, but also has anti-oxidation, anti-coagulation, anti-thrombotic, anti-tumor, anti-inflammatory, anti-bacterial, liver-protecting and other immunoregulatory effect...
