“…Using a standard, the main cyanidin derivative peak was identified as cyanidin -3 -O -glucoside. 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).…”

“…Species of the Rubus genus are known as natural sources of anthocyanins with high antioxidant effect (DEIGHTON et al, 2000). Due to the increasing interest in blackberry consumption and the knowledge that the nutritional composition varies according to the cultivar, this work aimed at evaluating the phenolic and anthocyanin content, antioxidant capacity and physicochemical quality of five blackberry cultivars grown in Brazil.…”

*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.

“…The TP content was determined according to the Folin-Ciocalteu method (Deighton, Brennan, Finn, & Davies, 2000;Singleton & Rossi, 1965). However, a drawback with the Folin-Ciocalteu approach is that compounds such as fructose, amino acids and ascorbic acid can contribute to the TP content.…”

a b s t r a c tExtracts of the white shaft and green leaves of 30 leek cultivars were investigated for their antioxidant properties, total phenolic (TP) and L-ascorbic acid (AA) content. The measured antioxidant properties included free radical scavenging activities against peroxyl (ORAC) and 2,2-diphenyl-1-picrylhydrazyl radicals (DPPH) and their Fe 3+ reducing capacity (FRAP). The results from this study suggest that the green leek leaves generally have significantly stronger antioxidant properties than the white shaft. Correlation analysis between the TP and the AA content and the antioxidant activity showed that phenolics and ascorbic acid contribute significantly to the antioxidant activity of leek. The three antioxidant activity assays were all correlated for the extracts of the white shaft of the 30 leek cultivars. Principal component analysis (PCA) elucidated the influence of part and type of cultivar on the antioxidant capacity, TP, and Lascorbic acid content, whilst the breeding strategy and seed company had no influence.

“…Contribution of phenolic compounds is one of the mechanisms of the overall antioxidant activities. This mainly due to their redox properties involve in the plant material [46]. However, Pearson correlation showed that there was a weak positive relationship (r=0.4713) found for antioxidant activity assayed by β-carotene bleaching assay with TPC.…”

This study aimed to characterize the different parts of Carica papaya (ripe and unripe papaya, leaves and seed), through their proximate composition, total antioxidant activity, and in vitro antiproliferative activities. Both macronutrients and micronutrients were determined using standard AOAC methods of analysis, while vitamin analyses were determined by High Performance Liquid Chromatography (HPLC). Results showed that the ripe papaya had the highest antioxidant activity (84.04%) followed by unripe papaya (81.35%), leaves (78.03%) and the least was seed (75.35%).The phenolic content was in the order of leaves>unripe papaya>ripe papaya>seed. HPLC analysis showed that papaya leaves exhibited the highest ascorbic acid and β-carotene content (85.60 and 3.86 mg/100 g respectively), while the seeds had the highest Vitamin E content (4.09 mg/100 g). Results obtained from cytotoxic activities showed that MCF-7 (hormone dependent breast cancer) and MDA-MB-231 (non-hormone dependent breast cancer) cell cultures were significantly inhibited by the extract. The antioxidant and antiproliferative activities of different parts papaya extracts indicate that the consumption of the whole fruit, ripe and unripe papaya, leaves and the seed supplies the important quantities of numerous necessary nutrients for human diet which includes vitamins A, C and E.
