Improved HPLC method for total plasma homocysteine detection and quantification.
Recent clinical research has pointed at hyperhomocysteinemia as an independent risk factor in a number of cardiovascular and neurological diseases. We have improved a chromatographic method of total plasma homocysteine measurements in order to obtain higher sensitivity, reliability and reproducibility. The method demonstrates excellent linearity (R=0.999), range (<2-100 microM), precision (inst...
متن کاملAn improved HPLC method for determination of colocynthin in colocynth
Background and objectives: Colocynthin is the major active secondary metabolite of colocynth, Citrullus colocynthis (L.) Schrad, which has been used in traditional and ethno medicine of many countries. It could be considered as an active marker for quality control of colocynth and its herbal products. Analysis and standardization of colocynth and its herbal preparations are a critical...
متن کاملQuantification of alkylresorcinol metabolites in urine by HPLC with coulometric electrode array detection.
BACKGROUND Whole-grain rye and wheat cereals contain high amounts of alkylresorcinols (ARs), phenolic lipids. ARs can be quantified in plasma. Two recently identified urinary AR metabolites, 3,5-dihydroxyphenylbenzoic acid (DHBA) and 3-(3,5-dihydroxyphenyl)-1-propanoic acid (DHPPA), may be useful as biomarkers of intake of whole-grain rye and wheat. METHODS We evaluated 4 pretreatment protoco...
