応用分野
用途光学分割剤。
天然物の起源A derivative of naturally occurring starch.
使用β-Cyclodextrin is a cyclic oligosaccharide produced from starch via enzymatic conversion. β-Cyclodextrin is commonly used to produce HPLC columns allowing chiral enantiomers separation.
一般的な説明Beta-Cyclodextrin is the most abundant and cheap cyclic oligosaccharide that forms inclusion complexes with several drug molecules. Its main application is in tablet and capsule formulations.Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
調製方法
Cyclodextrins are manufactured by the enzymatic degradation of starch using specialized bacteria. For example, β-cyclodextrin is produced by the action of the enzyme cyclodextrin glucosyltransferase upon starch or a starch hydrolysate. An organic solvent is used to direct the reaction that produces β-cyclodextrin, and to prevent the growth of microorganisms during the enzymatic reaction. The insoluble complex of β-cyclodextrin and organic solvent is separated from the noncyclic starch, and the organic solvent is removed in vacuo so that less than 1 ppm of solvent remains in the β-cyclodextrin. The β-cyclodextrin is then carbon treated and crystallized from water, dried, and collected.
製造方法Usually produced commercially from Bacillus macerans or B. circulans fermentation of starch or starch hydrolysate.
純化方法Recrystallise β-cyclodextrin from water and dry it for 12hours in a vacuum at 110o, or 24hours in a vacuum at 70o. The purity is assessed by TLC on cellulose containing a fluorescent indicator.
