Comparative Enantioseparation of Monoterpenes by HPLC on Three Kinds of Chiral Stationary Phases with an On-Line Optical Rotatory Dispersion under Reverse Phase Mode
enantioseparation chiral stationary phases monoterpenes
2009/6/17
HPLC enantioseparation of chiral monoterpenes was studied using amylose (AD-H), cellulose (OD-H) and β-cyclodextrin (CD-Ph), phenyl carbamate derivatives as chiral stationary phases (CSPs). The contri...
Optical Isomers and Odor Thresholds of Volatile Constituents in Citrus sudachi
enantiomeric ratio odor threshold odor quality limited odor unit value
2010/11/23
The enantioselective analysis of the volatile components in Citrus sudachi peel oils was achieved using an enantioselective capillary gas chromatography (enantio-cGC) with α- and β-cyclodextrin column...
Studies on the Optical Rotation of Whey Syrup Prepared by Immobilized β-Galactosidase
specific rotation whey syrup immobilized β-galactosidase
2010/11/23
Whey syrup was prepared by immobilized β-galactosidase and its specific rotation was determined. The rate of lactose hydrolysis and the specific rotation of whey syrup increased as the reaction time i...
