A high-performance liquid chromatographic (HPLC) method was developed for the determination of ascorbic acid in fruits, vegetables and juices. Samples were homogenized with 0.2 M phosphate buffer pH 2.0 and extracted with 3% metaphosphoric acid. Ascorbic acid was analyzed on a polymer C18 column ...
The ascorbic acid is widely used as antioxidant in food products. As this substance is a very unstable substance, its concentration needs an accurate monitorization. A RP-HPLC method was used for identification and quantification of ascorbic acid in mixtures used in sausage industry. Reliable ...
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...
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 ...

ascorbic acid, high performance liquid chromatography, feed additives, quantitative analysisL-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...
