“…The range of data submitted here for crude, hydrophilic and lipophilic antioxidants in strawberry concurs with the data published by several researchers (e.g., Cordenunsi et al 2005;Scalzo et al 2005), but is different from the data published by others (e.g., Garcia-Alonso et al 2004). Review of recent published papers reveals that many in vitro models and in vivo methods have so far been developed for the evaluation of antioxidant activity [for review see Tsao and Deng (2004)].…”

Khanizadeh, S., Ehsani-Moghaddam, B. and Levasseur, A. 2006. Antioxidant capacity in June-bearing and day-neutral strawberry. Can. J. Plant Sci. 86: 1387-1390. The present study was carried out to estimate the crude, hydrophilic and lipophilic antioxidant content of known and new advanced selections among June-bearing and day-neutral genotypes using Trolox equivalent antioxidant capacity method. Crude, hydrophilic and lipophilic extractions were prepared using 25 g of frozen fruits from each sample. In June-bearing strawberries, significant differences were observed among crude, hydrophilic and lipophilic antioxidant values of different selected genotypes. Mean of crude, hydrophilic and lipophilic antioxidants in June-bearings were estimated to be 20.4, 13.4 and 0.5 µmol TE g -1 FW, respectively, which were higher than those of the day-neutral genotypes (i.e., 13.2, 9.4 and 0.3 µmol TE g -1 FW). The present study revealed the importance of genetic background for determining the antioxidant potential in selected June-bearing genotypes and the possibility of production of new strawberry cultivars with higher levels of antioxidant capacity through breeding programs.

“…The highest cyanidin concentrations were detected in Guarani and Caingangue cultivars (about 150 mg.100 g -1 ), values higher than those detected for domestic and wild species grown in China (1-118 mg.100 g -1 ) (DEIGHTON et al, 2000). Also, data shown for blackberry fruits are superior to anthocyanin contents found in other red fruits, such as strawberry (30 to 60 mg.100 g -1 , CORDENUNSI et al, 2003), purple Surinam cherry (16.23 mg.100 g -1 , LIMA et al, 2005) or acerola (3.79 to 59.74 mg.100 g -1 , LIMA et al, 2003).…”

*A quem a correspondência deve ser enviada Physico-chemical characterization and bioactive compounds of blackberry fruits (Rubus sp.) grown in BrazilCaracterização físico-química e de compostos bioativos em amora-preta (Rubus sp.) cultivada no BrasilNeuza Mariko Aymoto HASSIMOTTO 1 , Renata Vieira da MOTA 2 , Beatriz Rosana CORDENUNSI 1 *, Franco Maria LAJOLO 1 IntroductionFruit and vegetable intake has proven to reduce the development of a considerable number of chronic diseases, such as cancer and cardiovascular diseases. The protective effect evidenced in laboratory and epidemiological studies has been associated with a variety of nutrient and non-nutrient constituents, being many of them characterized by their antioxidant properties (PIETTA, 2000). Among the compounds with high antioxidant capacity are ascorbic acid, tocopherols, β-carotene and phenolic compounds, especially flavonoids (DREWNOWSKI; GOMEZ-CARNERO, 2000).Anthocyanins, the glycoside form of the anthocyanidins, belong to a class of flavonoids which present water-soluble pigments responsible for the orange, red and blue colors of many fruits, vegetables, leaves, flowers and roots. Anthocyanidins vary with different hydroxyl or methoxyl substitutions in their basic structure, flavylium (2-phenylbenzopyrillium). Only six of the 16 anthocyanidins identified in natural products occur frequently and in many different vegetables and fruits: cyanidin, pelargonidin, delphinidin, peonidin, petunidin and malvidin (WU; PRIOR, 2005a;. Anthocyanins are highly studied compounds because of their effects on human health as antioxidant compounds, as shown in a number of in vitro and in vivo studies HEINONEN, 2003), for their anti-inflammatory effect modulating ciclooxygenase 1 and 2 enzymes (TALL et al., 2004) and their inhibitory effect on the development of some cancer cells (HAGIWARA; YOSHINO; ICHIBARA, 2002).Among the small fruits group, including strawberry, raspberry, blueberry and blackberry crops, blackberry appears as the richest source of anthocyanins, with cyanidin content ranging from 93 to 280 mg.100 g -1 fresh weight depending on the cultivar (CONNOR et al., 2002), followed by black raspberry (up to 197 mg), blackberry (153 mg) and strawberry (32 mg) (WANG; LIN, 2000). Blackberry plants were introduced in Brazil by the Estação Experimental de Pelotas (RS), renamed ResumoCinco cultivares de amora-preta (Rubus sp.) foram avaliadas quanto a sua capacidade antioxidante, perfil de compostos bioativos e composição físico-química. Os níveis de ácido ascórbico total, presentes na forma de ácido desidroascórbico, variaram entre 9,8 a 21,4 mg.100 g -1 (b.u.). Os principais flavonóides presentes nas cinco cultivares foram: a antocianina cianidina (66 a 80% do total de flavonóides); o flavan-3-ol epicatequina; e os flavonóis quercetina e traços de caenferol. As cinco cultivares apresentaram alta capacidade antioxidante quando avaliadas pelo sistema de co-oxidação β-caroteno/ácido linoléico, similar ao antioxidante sintético BHT, na concentração de 50 µM.

“…Velioglu et al (1998) reported that 80% aqueous methanolic extracts from blueberry and sweet cherry showed strong antioxidant activity (92.1 and 82.5%, respectively) using the β-carotene bleaching method. On the other hand, using this same method, Cordenunsi et al (2005) found that 70% aqueous methanolic containing 5% acetic acid extracts from Dover, Campineiro, and Oso Grande strawberry cultivars presented antioxidant activities of 55.2, 51.7, and 56.6%, respectively. Different extraction procedures can strongly infl uence the composition of the extracts and their antioxidant activity.…”
