Routine sample preparation and HPLC analysis for ascorbic acid (vitamin C) determination in wheat plants and Arabidopsis leaf tissues.
Plants have developed various mechanisms to protect themselves against oxidative stress. One of the most important non-enzymatic antioxidants is ascorbic acid. There is thus a need for a rapid, sensitive method for the analysis of the reduced and oxidised forms of ascorbic acid in crop plants. In this paper a simple, economic, selective, precise and stable HPLC method is presented for the detec...
متن کاملDetermination of Vitamin C (Ascorbic Acid) in Orange Juices Product
This research describes a voltammetric approach to determine amounts of vitamin C (Ascorbic acid) in orange juice sample, using three screen printed electrode. The anodic currents of vitamin C were proportional to vitamin C concentration in the range of 0 – 10.0 mM with the limit of detection of 1.36 mM. The method was successfully employed with 2 μL of the working solution dropped on the elect...
متن کاملPreliminary Note on the Structure of Ascorbic Acid (vitamin C).
in each case varied during the succeeding days and the general attitude varied from extreme lassitude and drowsiness on the one hand to hyperesthesia and clonic spasms on the other. The height of the clinical reaction occurred on the 7th to 9th days, retrogressing to normalcy on the 14th day with the animals remaining normal on the 20th day. Using a very active sample of the same virus, White L...
متن کاملEncapsulation of Vitamin C (ascorbic Acid and Amla Pulp) to Develop Vitamin C Fortified Ice Cream
In this research study, two percentage of alginate as wall material and 0.1m cacl2 as hardening bath were optimized for encapsulation (bead formation) through extrusion process. The encapsulation efficiency (ee) at 500mg of ascorbic acid was highest (74%) compared to 750 mg and 1000mg. Ee was highest (95%) at 40g for amla pulp. Encapsulated ascorbic acid beads had significantly higher the conte...
متن کاملComputational studies on the interaction of vitamin C (ascorbic acid) with nitrogen modified TiO2 anatase nanoparticles
Density functional theory calculations were performed to investigate vitamin C interaction withN-doped TiO2 anatase nanoparticles. The adsorption of vitamin C on the energy favorable fivefoldcoordinated titanium sites was investigated. Various adsorption geometries of vitamin C towardsthe nanoparticle were examined. Since the adsorption energies of N-doped nanoparticles are higherthan those of ...
