Vitamin C (L-AA, ascorbic acid) has major functions in oxidative stress defense (e.g. ozone, pathogens, wounding, etc.) because of its antioxidant properties, and this leads to improved fruit quality, storage and increased resistance to postharvest storage diseases. It also protects humans from various important diseases. Fruit is the best food source of vitamin C, but while apple is the most h...

The effect of the application of 1-methylcyclopropene (1-MCP) and wax emulsions, alone or combined, on composition analysis, vitamin C, polyphenols, and antioxidant capacity of soursop was evaluated. Fruits were stored as follows: at 25 °C (control), and at 16 °C: fruits sprayed with candelilla or flava emulsions, fruits treated with 1500 nL/L of 1-MCP (20 °C, 12 h), and fruits treated with 1-M...

Research has been on-going on many plant materials, especially those discarded as waste, to exploit their nutritional and antinutritional properties. This is as a result of the United Nations’ millennium development goal to eradicate extreme poverty and hunger. Avocado (Persea americana Mill) seeds are often discarded after taking the pulp of the fruit. This study is aimed at evaluating the eff...

conclusions this study revealed that vitamin c could reduce the fibronectin accumulation effects of nicotine on kidney. results ihc results showed that fibronectin reaction significantly increased in proximal convoluted tubules of exp 1 compared with the control offspring; on the other hand, fibronectin reaction decreased in the mice offspring of exp 2. gene expression results showed that fibro...

The ellagic acid, total phenolic, and vitamin C contents in four raspberry cultivars (Heritage, Autumn Bliss, Rubi, and Zeva) grown in Spain were detected and quantified by HPLC in fresh, just frozen, and stored fruits at -20 degrees C for a one year period. Ellagic acid [207-244 mg kg(-)(1) of fresh weight (fw)], total phenolic (137-1776 mg kg(-)(1) of fw), and vitamin C (221-312 mg kg(-)(1) o...

BACKGROUND Antioxidant vitamins such as alpha-tocopherol (vitamin E), ascorbic acid (vitamin C), and beta-carotene (provitamin A), play a significant role in protecting the body from an excess of free radicals. The vitamin content of the diet is thus very important. OBJECTIVE To assess whether the dietary intake of vitamins A, C and E is adequate in a selected group of adolescents living in W...

sulforaphane is a strong anticarsenogen compound which is produced in broccoli. it seems salt stress improves sulforaphane production via systemic acquired resistance. to obtain suitable salt concentration and for having more content of sulforaphane with controlling germination percentage, nacl in 5 levels 0, 50, 100, 150, 200 mm (0, 4.53, 9.125, 13.68, 18.25 ds/m ) and salicylic acid in 3 leve...
