A robust and rapid high-pressure liquid chromatography–electrochemical detection (HPLC–ECD) method was developed and validated for the accurate determination of ascorbic acid (AA) and uric acid (UA), in human plasma. Dehydroascorbic acid (DHAA) was indirectly measured by subtracting native ascorbic...
L-Ascorbic acid is a difficult vitamin to quantitate by HPLC due to its low retention and poor resolution using the previously available column technologies. This is particularly evident in aquatic feed and meals, where various interferences deter the vitamin''s accurate determination and quantitation...
Calibration curves for ascorbic acid (Mallinckrodt, Paris, KY, USA), capsaicin (purity 95%), and dihydrocapsaicin (purity !90%) (Sigma–Aldrich, St. Louis, MO, USA) were prepared through serial dilution of different concen- trations of standards and area. The Perkin Elmer HPLC system (...
A new simple, rapid and sensitive reversed-phase liquid chromatographic method was developed and validated for the simultaneous determination of ascorbic acid (ASC) and salicylamide (SAL) in their combined dosage form. The analysis was carried out on CLC Shim-pack C8 column (250 x 4.6 mm, 5 ...
