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 assays: 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and β-carotene/linoleic acid tests and the results were compared with the synthetic standard antioxidant butylated hydroxytoluene (BHT). Results: Total phenolic contents of the samples are also estimated by Folin-Ciocalteu's phenol test. In both DPPH β-carotene/linoleic acid tests in the concentration of 2 mg/ml, only samples from cultivar A showed moderate antioxidant activity with 63.92±0.42 and 6.02±0.03 inhibition percentages, respectively and other samples were weakly active. Conclusion:The Folin-Ciocalteu's phenol test was also showed very little phenolic compounds for the fruits. In conclusion, weak antioxidant activity was estimated for the studied apple cultivars.

“…In all treatments, a higher content of individual phenolics as well as total phenolics was measured in apple peel as compared with the content in pulp (table III and IV). Many authors report the differences in the content of phenolic compounds in apple pulp compared with skin [7,19,20]. These findings confirm that apple phytoprotective compounds are mainly localized in the skin, which is the first barrier for pathogen penetration [21].…”

-Introduction. Apple fruit contains many compounds with positive effects on human health but even small pesticide residues from integrated production cause many food safety issues for consumers. Materials and methods. The apple fruits from different types of production: organic, integrated and two combined systems were analyzed. Their contents of sugars and organic acids were quantified with the use of HPLC with RI and UV detectors, and phenolic contents from apple skin and pulp were detected with HPLC-MS. Apple quality was also determined in terms of weight, firmness and color. Results. Organically produced fruits had 14% lower weight than integrated fruits, as well as 15% higher firmness and less green skin color than apples from the other three treatments. Among primary metabolites, the sum of sugars (fructose, glucose, sucrose and sorbitol) as well as organic acids (malic and citric) was highest in the integrated production treatment. Among secondary metabolites, eighteen individual phenolic compounds were determined separately in apple peel and pulp. They were classified into four groups: hydroxycinnamic acids, flavan-3-ols, dihydrochalcones and flavonols. The majority of the identified compounds were dependent on the applied management system. Their concentrations were mainly highest in the organic treatment due to higher stress levels. The multivariate analysis of all monitored parameters placed organic production into one group and presented a similarity among the other three management systems.Slovenia / Malus domestica / fruits / integrated plant production / organic agriculture / proximate composition / quality / Hplc Analyse de certains métabolites primaires et du profil phénolique de pommes 'Golden Delicious' issues de quatre systèmes de production.Résumé -Introduction. La pomme contient de nombreux composés ayant des effets positifs sur la santé humaine, mais les résidus, même faibles, de pesticides issus de productions inté-grées provoquent de nombreux problèmes de sécurité alimentaire pour le consommateur. Matériel et méthodes. Les pommes issues de différents types de production (biologique, intégré et deux systèmes combinés de production) ont été analysées . Leur teneur en sucres et en acides organiques ont été quantifiées par utilisation de l'HPLC avec des détecteurs RI et UV ; les contenus phénoliques de la peau et de la chair des pommes ont été détectés par une HPLC-MS. La qualité des pommes a été également déterminée en termes de poids, fermeté et couleur du fruit. Résultats. Les fruits produits de façon biologique ont présenté un poids infé-rieur de 14 % par rapport aux fruits produits par un système intégré; leur fermeté a été amélio-rée de 15 % et leur couleur de peau a été moins verte que celle des pommes en provenance des trois autres traitements. Parmi les métabolites primaires, la somme des teneurs en sucres (fructose, glucose, saccharose et sorbitol) ainsi que celle des teneurs en acides organiques (acide malique et citrique) ont été les plus élevées pour les pommes issues d...

“…Genetically, any factor that causes expression of genes leading to anthocyanin synthesis, also results in the expression of genes necessary for quercetin synthesis (Bakhshi and Arakawa 2006). Moreover, Lata et al (2009) indicated that there was a significant difference between different apple genotypes for catechin. Our results showed that addition of more cyanidin-3-glucoside to Malas Syabe Lorestan and Malas Yazdi leads to higher levels of total anthocyanin too.…”

“…Previous study of Ghasemnezhad et al (2013) showed that concentration of total phenolics of both chitosan-coated and uncoated pomegranate arils decreased significantly during cold storage. The decrease in phenolic compounds might be due to cell structural breakdown as part of senescence during storage and depends on the type of genotype (Lata et al 2009). In addition, the reduction of phenols might be due to oxidation of phenolic compounds accelerates with PPO and POD activities (Gil et al 1996).…”

In this study, the quality of minimally processed different Iranian pomegranate genotypes was investigated during storage at 4°C for 14 days. The results showed that at the end of storage time, the lowest microbial count was found on the arils of "Torsh Syabe Lorestan" genotype. There was a significant difference in titratable acidity, total soluble solids, total anthocyanin, catechin, and quercetin content in most genotypes after 14-day cold storage; while no difference was found between studied genotypes in antioxidant capacity, total phenolic, and flavonoid content. In general, total phenolic content and antioxidant capacity of pomegranate arils gradually decreased over storage time. Diphenolase activity of polyphenol oxidase (PPO) enzyme with dopamine hydrochloride substrate and peroxidase (POD) decreased over storage time, whereas diphenolase activity of PPO with pyrocatechol substrate significantly increased. The lowest diphenolase activity with dopamine hydrochloride and pyrocatechol substrates, as well as POD activity was found in Torsh Syabe Lorestan . The results suggested that the genotype of Torsh Syabe Lorestan , which showed the lowest microbial count on the arils and enzymes, could be more appropriate for minimal processing technology.
