| titleOfInvention | Method for preparing Chinese medicinal extract absorption component group |
| abstract | The invention discloses a method for preparing a traditional Chinese medicine extractA method for absorbing component groups belongs to the technical field of analytical chemistry, and can solve the problem that the prior art is difficult to integrally prepare multi-component compounds which take effect in traditional Chinese medicine extracts. The method comprises preparing a liquid-liquid two-phase system I; obtaining the distribution coefficient logK of the absorption component group to be prepared in the liquid-liquid two-phase system I 1 A range value; according to the distribution coefficient logK 1 The range value and the stationary phase retention value of the liquid-liquid two-phase system I in the high-speed counter-current chromatograph are used for obtaining the collection time of the absorption component group to be prepared; preparing the absorption component group in the traditional Chinese medicine extract by adopting a high-speed counter-current chromatography according to the collection time of the absorption component group to be prepared. The method of the invention obtains the distribution coefficient logK of the absorption component group to be prepared in the liquid-liquid two-phase system I 1 The range value is that the compounds in the Chinese medicinal extract are divided into absorption component group and non-absorption component group, and the absorption component group of the Chinese medicinal extract is prepared by high performance counter current chromatography. |
