The objective of this study was to determine and compare the sugar profile, distribution in fruits leaves sink-source relationship three strawberry ('Favette', 'Alba' 'Clery') blueberry cultivars ('Bluecrop', 'Duke' 'Nui') grown organic (OP) integrated production systems (IP). Sugar analysis done using high-performance anion-exchange chromatography (HPAEC) with pulsed amperometric detection (PAD). results showed that monosaccharide glucose fructose disaccharide sucrose were most important...

In this study we analysed mineral composition of bee pollen different plant origin collected across Serbia using inductively coupled plasma - optical emission spectrometry. The most abundant elements were potassium, calcium, and magnesium. samples also exceptionally rich in iron zinc, which are very important as nutrients. Judging by our findings, much more depends on the type pollen-producing than its geographical origin.

The aim of this study was to compare total phenolic content (TPC), radical-scavenging activity (RSA), anthocyanin (TAC), sugar and polyphenolic profiles two apple cultivars (‘Discovery’ ‘Red Aroma Orelind’) from organic integrated production systems in climatic conditions Western Norway. Sixteen sugars four alcohols 19 polyphenols were found the peel, but less detected pulp. peel both apples had significantly higher TPC RSA than apples, while TAC integrated. Sucrose glucose levels apples;...

Total phenolic content (TPC), total anthocyanin (TAC), free and ellagic acid content, sugars, minerals, radical-scavenging activity were determined in nine berries harvested Serbia. More than 30 compounds identified; among them, 11 polyphenols cis,trans-abscisic quantified using UHPLC coupled with an LTQ-Orbitrap XL mass analyzer. For the first time chrysin, naringenin, pinocembrin, galangin some of investigated berry species. The extraction efficiency two systems, methanol acetone, was...

Background and Aims Retranslocation of iron (Fe) from source tissues enhances plant tolerance to Fe deficiency. Previous work has shown that silicon (Si) can alleviate deficiency by enhancing acquisition root shoot translocation Fe. Here the role Si in mobilization older leaves subsequent retranslocation young cucumber (Cucumis sativus) plants growing under Fe-limiting conditions was investigated. Methods Iron (57Fe or naturally occurring isotopes) measured at different positions on...

In this work, 12 apple cultivars grown organically in three regions of Norway (Telemark, Ullensvang, Viken) were analyzed terms fruit quality, with the aim equating different growing under specific climatic conditions. Apples for concentration levels minerals, sugars, sugar alcohols, organic acids, total phenolic content (TPC), radical scavenging activity (RSA), and profiles. Discovery “Rose” from Telemark stored highest level minerals (24,094.5 mg/kg dry weight). Glucose, fructose, sucrose,...

To date little has been done on identification of major phenolic compounds responsible for anticancer and antioxidant properties pea (Pisum sativum L.) seed coat extracts. In the present study, profile extracts from 10 differently colored European varieties determined using ultrahigh-performance liquid chromatography–linear trap quadrupole orbitrap mass spectrometer technique. Extracts dark with high total content (up to 46.56 mg GAE/g) exhibited strong activities (measured by...

Chemical characterizations of leaves and fruits that were obtained from organically integrally produced strawberries ('Favette', 'Alba', 'Clery') blueberries ('Bluecrop', 'Duke', 'Nui') western Serbia undertaken in this study. Phenolic analysis was done while using ultra-high performance liquid chromatography coupled to a linear ion trap-Orbitrap hybrid mass analyzer, total phenolic content (TPC), anthocyanin (TAC), radical-scavenging activity (RSA) by spectrophotometry. In general,...

The main focus of this study is to assess radical scavenging and antimicrobial activities the 11 wood extracts: oak (Quercus petraea (Matt.) Liebl., Q. robur L., cerris L.), mulberry (Morusalba myrobalan plum (Prunuscerasifera Ehrh.), black locust (Robinia pseudoacacia wild cherry (Prunus avium L.). High-performance thin-layer chromatography (HPTLC) provided initial phenolic screening revealed different chemical patterns among investigated extracts. To identify individual compounds with...

Physicochemical, sensory, and health-related characteristics of peach wine produced from Redhaven variety selected white wines various grape varieties were determined compared. The alcohol content, titratable acidity, total extract was significantly lower compared with that wines, while its pH value higher. content phenolics (TPC) flavonoids (TFC) (402.53 mg/L GAE 332.67 mg CAE/L, respectively) have been found higher in comparison (TPC range 243.67–319.00 GAE, TFC 129.67–175.17 CAE/L). main...

The European pear psylla, Cacopsylla pyri L. (Hemiptera: Psyllidae), is one of the most serious arthropod pests pear. Since proper control this pest essential, better understanding complex plant–pest relationship mandatory. This research deals with constitutive polyphenolic profiles in leaves 22 cultivars diverse origin (P. communis, P. pyrifolia, and pyrifolia × communis) different resistance to psylla. study was designed show which differences profile from resistant susceptible could be...

In this study, grapes and corresponding wines of Merlot /No 022, 025 029/ Cabernet Franc 02, 010 012/ clones (recently developed) were evaluated regarding the total phenolic content, anthocyanin radical scavenging activity, aiming to better understand their quality market potential. The nineteen individual polyphenols quantified in studied grape samples using UHPLC coupled a triple-quadrupole mass spectrometer. mother used as relevant standards. grape, characteristics monitored at three...

Oblačinska sour cherry, an autochthonous cultivar, is the most planted cultivar in Serbian commercial orchards. Owing to its long cultivation under different agro-ecological conditions, it a mixture of clones. To obtain comprehensive information on cherry fruit, total carbohydrate composition, phenolic content, anthocyanin antioxidant activity and polyphenolic profiles 39 clones were investigated.Fructose was found be dominant sugar, followed by glucose, sorbitol sucrose. Rutin chlorogenic...
