Abstract

The invention belongs to the field of natural organic chemistry and relates to a novel method for extracting total flavonoids from wild euphorbia helioscopia in Greater Khingan Mountains and particularly relates to a novel method for extracting total flavonoids through ultrahigh pressure (ionic liquid as a solvent) extraction, polyamide coupled macroporous resin adsorption as well as separation and purification by using a high-speed counter-current chromatography. The method has the advantages that 1, ionic liquid is combined with ultrahigh pressure, so that the advantages of higher extraction speed and high efficiency are achieved; moreover, the process is simple, convenient and feasible, the effective components are sufficiently extracted, and the content of alkaloids is high; 2, a polyamide coupled macroporous resin adsorption and purification technology can be used for well enriching total alkaloids and further purifying the effective components; the resin is easy to treat, rapid in separation, low in expense and capable of realizing industrial utilization; 3, the high-speed counter-current chromatography has the advantages of flexibility in operation, high efficiency, high separation speed, large preparation amount, low expense and the like, and can be used for industrial application. By using the method, the obtained total flavonoids are high in content and high in purity up to 98.3%.
