Aims: The aim of the current paper is to identify the ascorbic acid level in ten commercially available fruits in order to expand the existing database about fruits rich in Vitamin C and to promote their daily consumption. Study Design:  Research was conducted experimentally. Place and Duration of Study: University of food technologies, Plovdiv, Bulgaria, October 2019. Methodology: Ascorbic acid levels were determined with the use of two oxidation-reduction titration methods – Dichlorophenoliodophenol (DCPIP) and N-Bromosuccinimide (NBS). Results: All studies samples possessed different amounts of ascorbic acid. Both DCPIP and NBS assay resulted in determining strawberries as the fruit with the highest ascorbic acid levels – 55.1 ± 1.6 mg/100 g and 59.8 ± 2.2 mg/100 g respectively. Lowest values were obtained for fig. All results are commensurable to those obtained in other studies. Ascorbic acid levels were as follows: strawberries > grapefruit > pear > green apple > blueberries > quince > banana > plum > white grapes > fig. Conclusion: In this study, ten commercially available fruits were studied for their ascorbic acid levels. Comparison between two titration methods showed moderate differences in the results confirming that the NBS method is more sensitive. All reported data confirms that differences occur, but fruits can be considered sources of vitamin C.

Basic Diet

Groups of guinea pigs on a basic diet of commercial rabbit pellets supplemented by fresh green grass or stored roots exhibited marked differences in the ascorbic acid level of their plasma. These differences were not accompanied by any significant variation either in the complement titer of the serum or the prothrombin time of the plasma. Such minor variations as were observed in these two activities did not parallel each other.

The 19Th Century

Scurvy was a common 18th century disease caused by vitamin C deficiency. It presents with multiple non-specific symptoms and can lead to capillary fragility due to impaired collagen synthesis. We report the case of a 63-year-old woman who presented with fatigue, nausea and progressive skin lesions consisting of multiple ecchymoses on the legs as also described in the diary drawings of a navy doctor in the 19th century. The ascorbic acid level was undetectable low in the patient’s serum. However, treatment with 500 mg ascorbic acid daily dramatically improved the skin lesions within 5 days.

This work was carried out for the quantitative estimation of phenolic compounds (soluble phenolic compounds, flavonoids such as quercetin, cynaroside, and avicularin) and ascorbic acid level in the aerial plant parts (leaves and stems) of two sage species viz., Salvia tesquicola (dry-steppe sage) and Salvia verticillata (lilac sage) grown in Tatarstan and Crimea, Kazan, Russia respectively. The highest content of phenolic compounds and the ascorbic acid level was reported in the leaves, while the value of these chemical constitutes was lowest in the stems of both species. Further, it has been shown, that these plants are rich in all investigated chemicals but among these Cynaroside and avicularin are the predominated flavonoids (cynaroside, quercetin, and avicularin). The amount of all studied active compounds differed significantly and it depends on the plant organs, species, and place of growth. Further, the results of the study revealed that the content of soluble phenolic compounds in sage plants did not depend on the species and place of growth while the growing conditions had a greater impact on the amount of flavonoids and vitamin C contents.

Severe Water Stress

Grafting is an easy way to produce a new seedling, which can tolerate against various stresses. During the acclimation after grafting, however, the seedlings still suffer a severe water stress. It is well known that water stress produces active oxygen to oxidize ascorbic acid. The concentration of ascorbic acid in the leaves was analyzed by HPLC equipped with an electrochemical detector. The column used was SP-120-5-ODS-BP (DAISO, JAPAN) and elution was performed with 0.1 ᴍ phosphate buffer, pH 3.0. After grafting the seedlings were acclimated under a 6-hr light/dark regimen. The content of ascorbic acid increased gradually during 2 days compared with control. The ascorbate peroxidase showed about constant activity, so the increase of ascorbic acid may be due to its requirement to cure the grafting

Background: Nutritional status in relation to selected biochemical parameters and also nutrient intakes in the pre-eclampsia and eclampsia was assessed in 52 patients and compared with that of 52 normal pregnant (NP) women. Serum calcium, ascorbic acid and blood Hb levels in the pre-eclamptic and eclamptic patients were significantly lower than the values of NP women. By unpaired t-test demonstrated in our study, the serum calcium, ascorbic acid and blood Haemoglobin (Hb) level were highly significantly different but not correlated with each other when compared among these groups. However, total statistical analysis revealed that among all the factors studied serum calcium level, ascorbic acid level and blood Hb level have effect on nutritional status of pre-eclampsia and eclampsia.DOI: http://dx.doi.org/10.3329/bjnut.v24i0.14032 Bangladesh J.
