摘要
Abstract
Objective: To improve the properties of marigold oleoresin included by cyclodextrins. Methods: The components of marigold oleoresin were analyzed by HSCCC (high-speed counter-current chromatography) and HPLC.The inclusion constants were tested by UV spectrophotometry.The complexes were prepared by trituration and the optimum inclusion condition was determined by the solubility and stability of the complexes. Results,The chromatography results showed that marigold oleoresin was a mixture of many different compounds.The inclusion constants also indicated strong inclusion action between xanthophyll and cyclodextrins,and mixed-cyclodextrins were superior to single cyclodextrin.Improved inclusion effects vary with different cyclodextrin,the β-cyclodextrin inclusion had poorer solubility,but better stability than HP-β-cyclodextrin inclusion. Mixed- cyclodextrins inclusion excel in both solubility and stability, especially at the ratio of 9:1 (β-cyclodextrin: HP-β-cyclodextrin).Conclusion: Marigold Oleoresin included by mixed-cyclodextrin has much better properties such as solubility and stability than the simple addition of individual cyclodextrins,which can compensate the shortage of single type of cyclodextrin.关键词
