| titleOfInvention | A kind of method for separating and purifying β-elemene, γ-elemene and δ-elemene |
| abstract | A method for separating and purifying β-elemene, γ-elemene and δ-elemene belongs to the technical field of extraction and separation of traditional Chinese medicines. In the present invention, firstly, acetonitrile is used to dissolve the extract, and then the semi-preparative liquid chromatography is used to separate and purify the target eluent. After extraction with n-hexane, the extract was dried under reduced pressure to obtain the final product. The present invention adopts semi-preparative liquid chromatography as the core technology for the first time, and separates and purifies β-elemene, γ-elemene and δ-elemene from elemene extract, and establishes a new method from elemene. The process route of separating and purifying β-elemene, γ-elemene and δ-elemene from alkene extract. The process of separating and purifying β-elemene, γ-elemene and δ-elemene has an average purity of not less than 90%, the process is simple, the solvent recovery is convenient, and has strong practical value. |
