“…Several studies have shown the positive correlation between the TPC and TAA of fruits (Rufino et al, 2010;Oliveira et al, 2011;Rosso, 2013). Higher TPC values for the skin in relation to the flesh have been reported for several fruits (Larrauri et al, 1997;Isobe et al, 2004;Carbone et al, 2011;Ignat et al, 2011), which shows the nutritional contribution of this tissue, commonly discarded during fruit consumption.…”

“…The genetic variability, maturation stage of the fruits, environmental conditions, plant management system and soil fertility, along with the quantification conditions (extraction method), sample size, time and method of sample storage, selection of reagents and presence of interfering substances (such as sugars, waxes, fats, and chlorophyll), all affect TPC quantification (Carbone et al, 2011). These factors can explain the discrepancy between the TPC and the TAA values reported by different authors for feijoa fruits.…”

-The objective of this work was to quantify the total phenolic content (TPC) and total antioxidant activity (TAA) of fruit from Brazilian genotypes of feijoa (Acca sellowiana). Skin and flesh tissues of the fruit were evaluated for the Alcântara, Helena, Mattos, and Nonante cultivars, and for the 2316 accession. TPC and TAA were both assessed in aqueous and hydroalcoholic extracts, and TAA was assayed by the DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)] methods. The TPC values, for aqueous extracts of the skin and flesh tissues, were 114.9 and 88.3 mg gallic acid equivalent (GAE) per 100 g fresh weight (FW), respectively. The corresponding values for TAA determined by the DPPH method, the skin and flesh tissues, given as EC 50 (substrate concentration which leads to 50% reduction of the DPPH), were 10.7 and 39.7 mg FW per g DPPH, respectively; and, by the ABTS method, the TAA values were 12.01 and 8.33 µmol L -1 Trolox per g FW, respectively. The greatest values for TPC and TAA were obtained for 'Mattos' and 'Nonante', in the skin, and for 'Nonante' and accession 2316, in the flesh. Feijoa fruit has important functional value, particularly in the skin, characterized by high TPC and TAA.Index terms: Acca sellowiana, Feijoa sellowiana, DPPH and ABTS methods, flesh and skin characterization, functional food. Compostos fenólicos e atividade antioxidante em frutos de genótipos brasileiros de goiabeira-serranaResumo -O objetivo deste trabalho foi avaliar compostos fenólicos totais (CFT) e atividade antioxidante total (AAT) em frutos de genótipos brasileiros de goiabeira-serrana (Acca sellowiana). As avaliações foram realizadas na casca e na polpa dos frutos, nas cultivares Alcântara, Helena, Mattos e Nonante, e no acesso 2316. CFT e AAT foram determinados em soluções extratoras aquosa e hidroalcoólica, e, para AAT, foram utilizados os métodos DPPH (2,2-difenil-1-picrilhidrazilo) e ABTS [2,2'-azino-bis (3-etilbenzotiazolin) 6-ácido sulfônico]. Os valores de CFT em extrato aquoso na casca e na polpa foram de 114,9 e de 88,3 mg em equivalente de ácido gálico (EAG) por 100 g de matéria fresca (MF), respectivamente. Para AAT, em extrato aquoso, na casca e na polpa, no método DPPH, os valores de EC 50 (concentração de substrato para reduzir em 50% a concentração inicial de DPPH) foram de 10,7 e 39,7 mg MF por g de DPPH, respectivamente; e, no método ABTS, foram de 12.01 e 8.33 µmol L -1 de Trolox por g de MF, respectivamente. Os maiores valores de CFT e AAT foram observados em 'Mattos' e 'Nonante', na casca, e em 'Nonante' e no acesso 2316 na polpa. Os frutos de goiabeira-serrana apresentam importante valor funcional, especialmente no tecido da casca, caracterizado pelos elevados conteúdos de CFT e alta AAT.Termos para indexação: Acca sellowiana, Feijoa sellowiana, métodos DPPH e ABTS, caracterização de polpa e casca, alimento funcional.

“…Among abiotic factors, various studies have shown the impact of environmental parameters on the accumulation of polyphenols in plants, such as intense light, excessive temperature, salinity, drought, cold, and soil characteristics (Sánchez- Rodríguez et al 2011). Besides, polyphenols varied significantly with the species, the variety, and the physiological stage (Carvalho et al 2011;Carbone et al 2011;Gruz et al 2011). On the other hand, the distribution of these compounds depends on the considered organ and the nature of tissues and cells (Ouchikh et al 2011;Carbone et al 2011).…”

Changes in phenolic composition and biological activities were investigated in different Limoniastrum monopetalum L. organs. For that, 80% aqueous acetone extracts were used to estimate total phenolic contents and their antioxidant activities were evaluated using DPPHÁ and O 2 Á-radical scavenging activities and reducing power.The efficiency of organ extracts was tested against human pathogen strains. Ultimately, acid hydrolysis of all organs was subjected to RP-HPLC for phenolic identification. Results showed that flower extracts exhibited the highest polyphenol (65.42 GAE/g DW) and flavonoid (35.36 CE/g DW) contents. Stems were enriched in condensed tannin content (21.4 mg CE/g DW) and displayed the best antiradical activities and the highest reducing power. Besides, stem and gall extracts showed the highest efficiency against pathogenic bacteria as compared with those of flower. Concerning the antifungal test, a slight activity was found in gall extracts. The RP-HPLC showed a difference in phenolic compounds that varied as function of organ. In fact, the major phenolic compound varied as function of organ. Results suggest that L. monopetalum could be a promising source of biomolecules for therapeutic and nutraceutical industries and the difference between organs may be related to their physiological role.

“…It is obvious in whole fruits when the methanolic extract is used the contents of TPC, TFC as well as TAC are higher than in pressed juices (Kyzlink, 1990). In case of antioxidants there exist other scientific works which refer to the fact that high contents of TAC are typical of native cultivars and the consumption of juices is highly effective in human nutrition (Carbone et al, 2011 juices (Oh et al, 2006). Regarding ROS, apple juices are the most effective to hydroxyl radical (Lichtenthaler and Marx, 2005) and in particular, nitric oxide ( Jayakumar and Kanthimathi, 2011).…”

During the last century due to the changes in landscape management, in country people's lives and with intensive fruit-growing the native cultivars of apple fruit trees have been gradually disappearing. The aim of the study was to compare the juices made of native apple cider cultivars. The cultivars-'Boikovo' , 'Jadernicka moravska' , 'Kardinal zihany' , 'Panenske ceske' , 'Parmena zlata zimni' , 'Strymka' growing in the locality of the Litencicke Hills in the eastern part of the Czech Republic were selected. For comparison, the fruits of commercial 'Idared' cultivar were also included. The chemical composition, antioxidant capacity, phenols, flavonoids and ascorbic acid content and the influence of juices on scavenging activity of nitric oxide and hydroxyl radical were measured. The mutual ratio of examined properties which were found, provide information about qualities and possibilities of use of native cultivars. High antioxidant properties characterize the juice of native apple cultivars. In particular, the 'Strymka' cultivar contained 2,637.34 mg of AAE (ascorbic acid equivalent) per litre in case of antioxidant capacity. In the juice of this cultivar the value of 144.05 mg of ascorbic acid per litre was recorded. As regards the 'Panenske ceske' cultivar, antioxidant capacity was 2,548.38 mg of AAE l -1 and in relation to ascorbic acid, the value was 145.35 mg l -1 . Similarly, high values were observed in both cultivars concerning the scavenging effect of apple juices on hydroxyl radical and nitric oxide (the 'Strymka' cultivar 16.38% and 19.26%, the 'Panenske ceske' cultivar 16.31% and 18.60%).
