Method for rapidly extracting and separating eupatilin and jaceosidin from Artemisia vulgaris

The invention belongs to the technical field of traditional Chinese medicine extraction and separation, and discloses a method for extracting and separating eupatilin and jaceosidin from Artemisia argyi, the Artemisia argyi is soaked in an organic solvent, after soaking, the organic solvent and the medicinal material are separated and distilled to obtain an extract, the extract is dissolved in a petroleum ether-ethyl acetate-ethanol-water two-phase solvent, and the two-phase solvent is distilled to obtain the eupatilin and jaceosidin. And taking a counter-current chromatograph and a petroleum ether-ethyl acetate-ethanol-water solvent as a separation system, injecting a solution for dissolving the extract into a quantitative loop by using an injector, feeding a sample, turning on an ultraviolet detector, controlling the detection wavelength to be 254nm, collecting extracts corresponding to two chromatographic peaks in 160-180 minutes and 190-220 minutes, and removing the solvent to obtain jaceosidin and eupati
