Abstract

The invention discloses a method for preparing rhodioloside. The method specifically comprises the following steps that 1, a Chinese medicinal material, namely rhodiola rosea, is dried, pulverized, sifted and loaded into an extraction container; 2, a solvent is added into the material obtained in the previous step for reflux extraction several times, extracts are combined, and the solvent is recovered and concentrated to an appropriate quantity; 3, a concentrate liquid obtained in the previous step is adsorbed with macroporous resin to remove protein; 4, the concentrate liquid obtained in theprevious step is subjected to decolorizing treatment, and an eluent is used for conducting elution treatment; 5, a liquid obtained in the previous step is subjected to crystallization purification treatment. According to the disclosed method for preparing the rhodioloside, the content of the rhodioloside is high, convenience is provided for extraction, and not only is the environment protected, but also the cost is reduced. At the same time, the method is simple and rapid, the separation efficiency is high, and a good effect is achieved.

Description

technical field [0001] The invention relates to a method for extracting and preparing components of Chinese herbal medicines, in particular to a method for preparing salidroside. Background technique [0002] Rhodiola is a herbaceous plant belonging to the sedum family Rhodiola, which is a kind of traditional Chinese medicine. Salidroside in Rhodiola has the effects of reconciling yin and yang, nourishing the body, resisting hypoxia, and delaying aging. In the prior art, the extraction process of salidroside is complicated, the loss of active ingredients is large, the extraction yield is low, the cost is high, and resources are largely wasted. Contents of the invention [0003] In order to solve the above problems, the present invention proposes an environmentally friendly and low-cost salidroside preparation method. [0004] A kind of preparation method of salidroside designed by the present invention specifically comprises the following steps: [0005] (1) Dried, crus...
