| titleOfInvention | Method and application of comprehensive extraction of sweet tea glycosides, quercetin and ellagic acid |
| abstract | The invention discloses a method for comprehensively extracting sweet tea glycosides, quercetin and ellagic acid in sweet tea. The extraction method at least comprises five steps of polyamide separation, sweet teaside purification, acid hydrolysis, quercetin purification and ellagic acid purification . The present invention uses polyamide to efficiently separate plant polyphenols, and at the same time utilizes the difference in solubility of quercetin and ellagic acid to comprehensively extract sweet tea to obtain high-purity sweet tea glycosides, quercetin and ellagic acid, and improves the efficiency of the extraction. The comprehensive utilization value of sweet tea leaves greatly enhances economic benefits; the purity of sweet tea glycosides, quercetin and ellagic acid prepared by the invention are all higher than 95%, the recovery rate is higher than 90%, and the product color is good; The method provided by the invention has strong operability, low cost, no pollution, is suitable for industrial production, and not only realizes the comprehensive utilization of sweet tea resources, but also solves the problem of environmental pollution of sweet tea tea waste residues after water extraction of sweet tea glycosides. |
