Abstract

The invention discloses a method for extracting salidroside from rhodiola. The method comprises the following steps: cooling fresh rhizome of rhodiola to 8-12 DEG C, squeezing the fresh rhizome of rhodiola with a spiral juicer, filtering juice obtained by squeezing through sequentially using of a microfiltration membrane and an ultrafiltration membrane, combining filter residues obtained by filtration with residues obtained by squeezing to obtain a residue material; extracting the residue material by using a method of combining ethanol extraction with ultrasonic extraction to obtain extract; filtering the extract, adsorbing filtrate with a macroporous resin, and collecting eluent rich in salidroside; performing centrifugation, separation concentration and three-stage reverse osmosis concentration on the eluent rich in salidroside to obtain extractum, and drying the extractum through a microwave method to obtain salidroside powder. The method for extracting salidroside provided by the invention has advantages of high yield, low cost, low energy consumption and high purity.

Description

technical field

[0001] The invention relates to the technical field of salidroside extraction, more specifically, the invention relates to a method for extracting salidroside from Rhodiola rosea. Background technique

[0002] Rhodiola (Rhodiola) is a perennial herb or subshrub belonging to Rhodiola in the Sedum family. It is one of the rare medicinal plants and is known as "Plateau Ginseng". There are about 90 species of this genus in the world, and more than 70 species are distributed in my country. They are mainly produced in North China, Northeast China, Southwest China, Northwest China and Central China. Its chemical components mainly include flavonoids, tyrosol, salidroside, sitosterol, organic acids, volatile oil, polysaccharide, fat, protein, etc. Among them, salidroside and its aglycone tyrosol are the main active ingredients of Rhodiola rosea, and are also the most important indicators for evaluating Rhodiola rosea and its extracts. Modern pharmacological studies ...
