In this study, seven alkaloids were detected in Wu-tou decoction using ultra performance liquid chromatography coupled with tandem mass spectrometry (UPLC-MSn). The aim of this study was to investigate the effect of...
A novel 2,6-dimethyl-b-CD bonded and silica based HPLC chiral stationary phase(CSP) was prepared.The diphenylmethane diisocyanate(MDI) was applied for the first time in the immobilization of 2,6-dimethyl-b-CD onto...
The separation of enzymatic hydrolysis products of yeast RNA by ion-pair HPLC was studied.A modified chromatographic response function(MCRF) was proposed to appraise the effectiveness of chromatographic separation.T...
Cyclodextrin 1 was directly oxidized to the corresponding monoaldehyde 2 on their primary faces by cyclized 2-iodoxybenzoic acid(IBX) in DMSO, followed by the synthesis of β-cyclodextrin derivatives bearing Schiff-ba...
Based on the inhibitory effect of metal ions on the decolourization reaction of a dye taking place in a mixed micellar medium, a differential rate method was developed for the detection of metal ions. The present kine...
A sensitive high-performance chromatographic method for the detection of N-nitrosoamines with pre-column fluorescence derivatization has been developed.Eight representative N-nitrosoamines, which were separated on a r...
A high-performance liquid chromatographic method using uv detection for thedetermination of 10 drugs of abuse is described. The method is sample and sensitive. The linear rangesare 20 ̄100ng/ml with relative standard ...
