Determination of Ascorbic Acid in Oman Citrus Fruits

Determination of ascorbic acid in different citrus fruits under reversed phase conditions with UPLC

This study compared the concentration of ascorbic acid between citrus fruits collected from the farm of Kerman in Iran. Determination of ascorbic acid was carried out using a liquid chromatography coupled to a diode array detector, with reverse phase and isocratic elution. The validation parameters showed efficiency, adequate linearity, relative standard deviation values 0.02 % (n=10) for repea...

Determination of Ascorbic Acid Contents of Fruits and Vegetables

Ascorbic acid contents of some fruits and vegetables in Abakaliki were analyzed through titrimetric methods. The results recorded the concentrations (mg/100g) of ascorbic acids in various fruits as orange (15.47 ± 0.23), lemon (12.87 ± 0.45), grape (2.00 ± 0.10), paw-paw (46.40 ± 1.65), apple (2.20 ± 0.10), banana (1.87 ± 0.06), carrot (1.80 ± 0.04), pineapple (2.80 ± 0.10), water melon (2.27 ±...

Determination of L- Ascorbic Acid in Plasma by Voltammetric Method

Voltammetric techniques have been considered as important methods among the analytical techniques used for the identification and determination of trace concentrations of many biological molecules such as L-ascorbic acid (AA). L-ascorbic acid is an electro-active molecule, though it is difficult to determine its value directly with a majority of electrodes made of carbon and transition metals, ...
