“…These findings are in agreement with measured total phenolic contents of the samples (Drogoudi et al, 2008;Lata, 2007;D΄Abrosca et al, 2007;Tsao et al, 2005;Vieira et al, 2009). β-Carotene/linoleic acid test of 4 apple cultivars showed the same results as antioxidant test with the exception that cultivar A showed greater inhibitory power (%6) compared to DPPH procedure.…”

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.

“…Chinnici et al (2004) observed that the free radical scavenging activity of apple extracts not only depends upon the phenolic content but also on the individual phenolic profiles for both apple peel and pulp. Hence, variation in post-cut enzymatic browning among cultivars can also be attributed to the individual phenolic profile (Lata 2007;Lee et al 2003). Among the different phenolic compounds, quercetin, epicatechin, and procyanidin are found to have higher antioxidant capacity than vitamin C, phloretin, and chlorogenic acid, which suggests that most of the total antioxidant capacity is attributable to phenolic compounds rather than vitamin C (Eberhardt et al 2000;Lee et al 2003).…”

S. 2007. Biochemical characterization of enzymatic browning in selected apple genotypes. Can. J. Plant Sci. 87: 1067-1074. Enzymatic browning in apples (Malus × domestica Borkh.) caused by polyphenol oxidases (PPO) is the major factor responsible for the deterioration of quality in processed apple products such as juice, fresh-cut slices, and chips. Selected apple genotypes with a range of low post-cut enzymatic browning were investigated to understand the biochemical mechanisms leading to enzymatic browning. Post-cut enzymatic browning, polyphenolic profiles using LC-MS/MS, PPO activity, vitamin C, total antioxidant capacity using the Ferric Reducing Antioxidant Power (FRAP) and the Oxygen Radical Absorbance Capacity (ORAC), and elemental composition were determined in two recently released cultivars [Eden TM (also known as SJCA38R6A74) and SuperMac], and one new advanced line (SJCA16) and compared with two commercial cultivars (Empire and Cortland). Eden TM exhibited the least post-cut enzymatic browning as estimated by Whiteness Index. SJCA16 possessed a characteristic yellowish flesh color. Whiteness Index (WI) values were inversely related to chlorogenic acid, catechin and epicatechin contents present in apple slices. Vitamin C content showed a strong positive correlation with WI. Among the mineral elements, the content of copper had a strong positive correlation with PPO activity.

ÖZETBu çalışmada, üç farklı armut çeşidinde (Akça, Santa Maria ve Deveci) yapraktan üre uygulamasının verim, meyve kalitesi ve bioaktif bileşikler üzerine etkisinin belirlenmesi amaçlanmıştır. Tam çiçeklenmeden 30 ve 60 gün sonra üre içeren solüsyon (% 0 ve % 0,1 CH 4 N 2 O) tüm ağaçlara iki kez püskürtülmüştür. Kontrol uygulaması ile karşılaştırıldığında, verim, meyve ağırlığı ve geometrik ortalama çap, üre uygulaması ile önemli oranda artmıştır. Renk özellikleri, suda çözünebilir kuru madde, pH ve titre edilebilir asitlik değerleri üzerine üre uygulamasının istatistiksel bakımdan bir etkisi olmamıştır. Üre uygulaması, meyve eti sertliğini ve toplam fenolik madde içeriğini önemli oranda azaltmıştır. Tüm çeşitlerin toplam antioksidan aktivitesi üre uygulaması ile azalmıştır. Üre uygulaması; Akça ve Santa Maria çeşidinde naringenin, Deveci çeşidinde ise rutin içeriğini önemli oranda artırmıştır. Üre uygulaması, tüm çeşitlerin azot içeriğini, Deveci çeşidinde çinko, Santa Maria çeşidinde ise potasyum, kalsiyum ve magnezyum içeriğini de önemli oranda artırmıştır.Anahtar Kelimeler: Armut, üre, fenolik, mineral madde içeriği, verim THE EFFECT OF FOLIAR UREA TREATMENT ON YIELD, FRUIT QUALITY AND BIOACTIVE COMPOUNDS OF DIFFERENT PEAR VARIETIES (PYRUS COMMUNIS L.) ABSTRACTThe effects of foliar urea treatment on yield, fruit quality and bioactive compounds of three different pear cultivars (Akça, Santa Maria and Deveci) were investigated in this study. Whole trees were sprayed twice with an aqueous solution containing urea (0% and 0.1% CH 4 N 2 O) 30 and 60 days after the full bloom for each cultivar separately. The per tree yield, fruit weight and geometric mean diameter were significantly increased with urea treatment according to control. The color characteristics, soluble solids content, pH and titratable acidity didn't change with the urea treatment. The urea treatment significantly reduced fruit flesh firmness. Urea treatment significantly reduced total phenolic content of Santa Maria. Total antioxidant activity of all varieties significantly reduced with the urea treatment. Urea treatment significantly increased naringenin content of Akça and Santa Maria, and rutin content of Deveci pear. The nitrogen content of the pear varieties was significantly increased with urea treatment. Additionally, urea treatment significantly increased zinc content of Deveci, and potassium, calcium and magnesium content of Santa Maria pear.
