Production method for separation and purification of salidroside from rhodiola rosea

The invention discloses a production method for separation and purification of salidroside from rhodiola rosea. The method comprises the following steps: after being smashed, raw materials are thrown in from a throwing hopper; a mainframe of an extraction tank set rotates; the materials are slowly propelled from the front end of the set to the back end; and at the same time, extraction solvent is introduced in the extraction tank from a liquid inlet pipe at the tail end of the set, and penetrates the movable materials from the back end of the tank to flow to the front end; and the solid-phase and liquid-phase materials are fully contacted with each other in the inverse movement so as to extract the effective components of medicinal materials. Medicine dregs are forcedly pushed to a dreg outlet through a discharge conveyer for discharging, and are extruded by using a special juice extruder to extrude residual medicine juice from medicinal material organizations, so that the content of the residual medicine juice of the medicine dregs is reduced, the extraction efficiency is higher, and the extraction is more thorough. The method chooses macroreticular resins and combines with the silica column chromatography to purify, so that better separation effect is achieved. Finished products of salidroside with the highest yield of 1% and the content above 95% can be obtained.
