| titleOfInvention | The preparation method of high purity numb-taste component of zanthoxylum |
| abstract | The invention discloses a kind of preparation method of high purity numb-taste component of zanthoxylum, it adopts following processing step: (1) take xanthoxylum oleoresin as raw material, in xanthoxylum oleoresin, add polar solvent, stirs extraction, extraction liquid after filtration, after concentrated, drying, obtain solid substance; (2) in above-mentioned solid substance, add normal hexane, heated and stirred extracts, and filters and obtains filtrate; (3) filtrate is after cooling crystallization, crystallization, filtration, obtains white crystal; White crystal obtains numb-taste component of zanthoxylum crystal after adopting n-hexane, filtration, drying.Present method removes the use of various chromatography column from, and flow process is short, and preparation amount is large, has method reliably easy, saves cost, is easy to the feature obtaining high purity numb-taste component of zanthoxylum.Present method gained crystal enters performance liquid chromatographic column analysis, and purity, more than 90%, meets the application requiring of makeup and pharmaceutical field. |
