Thirty eight bottles of red wine (Carbanet Sauvignon) were randomly selected based on vintage, region, price, and age (number of months in a barrel). The total phenolic content of each wine was determined using Folin-Ciocalteau assay. The radical scavenging activity was evaluated using 2,2-diphenyl-1-picryhydrazyl (DPPH) assay. Apart from a few bottles that exhibited above average radical scave...

In 1912 Folin and Denis (1) published a series of methods for the analysis of blood and urine, all based on the principle of Nesslerization, and among those met.hods was one for the determination of ammonia in blood. By the help of this method Folin and Denis proved the then important point t.hat the relatively high ammonia content of portal blood is mostly putrefactive ammonia absorbed from th...

antibacterial, antifungal and antioxidant activities of methanolic crude extracts from aerial parts of four arnebia species namely arnebia fimbriopetala, arnebia linearifolia, arnebia garandiflora, arnebia tubata were screened. total phenolic contents were determined by folin-ciocalteu procedure and ranged from 2.2 ± 0.13 (a. fimbriopetala) to 1.6 ± 1.0 mg (arnebia tubata) gallic acid µmol equi...

objective: antioxidants are considered as the main factors in the inhibition of unwanted oxidation reactions. materials and methods: in this research the antioxidant potential of the fresh fruits of 4 cultivars (a to d) of malus domestica (m. domestica) cultivated in the kashan, qamsar area was evaluated. the antioxidant activity of the samples were evaluated using two complementary antioxidant...

The purpose of this study is to quantify the polyphenolic content and evaluated anti-inflammatory antioxidant activity four plants extracts Annona senegalensis, Ipomoea batatas, Terminalia superba Psidium guajava. Phenolic flavonoid contents were determined by Folin-Ciocalteu aluminum trichloride methods, respectively with ethanolic extract. was accessed DPPH FRAP methods. results analysis indi...

This work planned to assess the antioxidant prevention agent movement and phenolic content of 41 business restorative creams accessible on homegrown market. The phenol still up in air by Folin-Ciocalteu strategy involving gallic corrosive as a norm. cell reinforcement action was estimated utilizing FRAP (feric limit). 22.5% corrective inspected contained compounds between 2.89 -1.15 2.98-1.91 m...

Determinations of pure uric acid have been made by permanganate titrations for many years. The presence of other substances with uric acid in body fluids, which give permanganate values, has necessitated the separation of uric acid before the titration could be carried out. Such separations have never been perfect. Whether thrown down as such by treatment with stronger acids or precipitated as ...
