Two modes of liquid-liquid extraction in flow-injection systems were compared and applied to the fluorimetric determination of thiamine (Vitamin B(1)). The first included phase segmentation, but fluorescence was measured without phase separation. In this mode, thiamine was detected at concentrations

A new reversed-phase ion-pair high-performance liquid chromatographic (HPLC) method has been developed for the determination of the following bisphosphonic acids: alendronic acid (ALEN), etidronic acid (ETID), ibandronic acid (IBAN) and risedronic acid (RISE). Separation was achieved on a C(18) column

A liquid chromatographic method involving precolumn derivatization for determining thiamine and its phosphate esters in human blood has been optimized. Blood sample stored at - 20 degrees C were haemolysed and deproteinized by perchloric acid. The supernatants of the samples

Effects of the coenzyme thiamine pyrophosphate and its analogs on the inhibition of self-splicing of primary transcripts of the phage T4 thymidylate synthase gene (td) were investigated. Of all compounds tested, the coenzyme thiamine pyrophosphate was the most potent inhibitor

Fluorometric determination of thiamine requires the conversion of the analyte to fluorescent thiochrome by hexacyanoferrate(III) oxidation in alkaline solution and the isolation of the produced thiochrome from the reaction medium by solvent extraction. It was observed that thiochrome could be
