| Abstract: | Tribenzoyl-cellulose(CTB) was ultrasonically prepared by reaction of microcrystalline cellulose with benzoyl chloride and characterized by IR spectrometry and element analysis.The mixture of CTB and microcrystalline cellulose in certain propotion was used as chiral stationary phase(CSP) of thin-layer chromatography.Optimized of mobile phases and visualization,five chrial drugs were separated on the CSP,such as ofloxacin,propranolol,phenylalanine,N-methyl-β-hydroxyl-phenylethylamine and atropine.Enantiomers obtained were characterized by specific rotation,melting point,IR and 1H-NMR spectrometry and these datas were consistent with the reported. |
