Despite the fact that heat stress induced the production of ROS, the application of aqueous moringa dry leaf extract, moringa fresh leaf extract and moringa flower extract quite effectively alleviated the production of both MDA and H2O2, as evident from their contents in shoot and root, and enhanced the production of ascorbate, riboflavin and niacin in the shoot and root under control or heat stress in both the hybrids although performance of SB-11 was better than ICI-984 (Fig.
Stevioside lowered heavy metals accumulation level in roots and leaves of winter wheat germinating seedlings, decreased pollutants effects on plant growth, increased ascorbate peroxidase activity and proline content, which indicated its protective action on winter wheat plants under heavy metals caused stress.

But even normal levels of vitamin C inside the cell could be hazardous, and the new study sheds light on the specific ways in which the genotoxic potential of Cr(VI) is enhanced by ascorbate. First, the reduction of Cr(VI) by intracellular vitamin C results in dramatic increases in the formation of chromosomal breaks and gene mutations.
In Group C (green), the teeth were bleached in the same procedure as Group B, after washing away the bleaching agent for two hours, 10% sodium ascorbate solution was applied to the enamel surface of the embedded teeth as an irrigation solution for 10min at a flow rate of 1ml/min.
They can take high oral doses of vitamin C (ascorbic acid or sodium ascorbate).
[9,10] Recently, it was shown a low toxicity and hemo-protective properties of lithium ascorbate, which is an important advantage for medical application.
Humans and a few other species are unable to synthesize their ascorbate, as we lack the final enzyme GULO (Gulonolactone oxidase) in the ascorbate biosynthesis pathway [5].
Researchers have known for a while that people with lower levels of ascorbate (vitamin C) are at increased cancer risk, but no one knew why.
