Antioxidant activity, phenol and flavonoid contents of 13 citrus species peels and tissues.
Methanolic extracts of 13 commercially available citrus spp., peels and tissues growing in Iran were investigated for their antioxidant activity by DPPH method. IC50 for antioxidant activity ranged from 0.6-3.8 mg ml(-1). Total phenolic content of the citrus spp. samples (based on folin Ciocalteu method) varied from 66.5 to 396.8 mg gallic acid equivalent/g of extract and flavonoids content (ba...
متن کاملEffect of vitamin C on salivary total antioxidant capacity in healthy male smokers
Background and Aims: Saliva is the first body fluid that is exposed to the free radicals found in cigarette smoke. Antioxidant substances in saliva, such as vitamin C, play an important role in the defense mechanism against free radicals. Therefore, the aim of this study was to examine the effect of vitamin C on the total antioxidant capacity of saliva in smokers. Materials and Methods: This r...
متن کاملGenetic control of fruit vitamin C contents.
An F(1) progeny derived from a cross between the apple (Malus x domestica) cultivars Telamon and Braeburn was used to identify quantitative trait loci (QTL) linked to the vitamin C (l-ascorbate [l-AA]) contents of fruit skin and flesh (cortex) tissues. We identified up to three highly significant QTLs for both the mean l-AA and the mean total l-AA contents of fruit flesh on both parental geneti...

متن کاملEffect of Vitamin C on Salivary Total Antioxidant Capacity in Smokers
This study was designed to elucidate the effect of ascorbic acid on salivary total antioxidant capacity in smokers. In this single blind crossover clinical trial, the whole unstimulated saliva of 30 smokers, who were randomly divided into two groups, was collected. In the first phase after the saliva collection, one group of patients took 500 mg of vitamin C powder, for 3 weeks. Then, saliva of...
