| titleOfInvention | Method for preparing crocin III |
| abstract | The invention discloses a method for preparing crocin III, belonging to the technical field of separation and purification of active components of traditional Chinese medicines. The invention takes full-bloom buddleja officinalis as a raw material, and high-purity crocin III is obtained by extraction and concentration, macroporous resin enrichment, sephadex column chromatography and recrystallization, and the purity is more than or equal to 95 percent; the optimal extraction and enrichment process is obtained through optimization, so that the extraction efficiency and the purity of the crocin III are improved; the method for preparing the crocin III provided by the invention has the advantages of stable process, environmental protection, simplicity, convenience and feasibility, breaks through the current situation of the process flow of preparing the crocin III without standardization, and greatly improves the comprehensive utilization value of the buddleja officinalis. |
