“…Are soluble in water, potent antioxidants and responsible for the astringency of many fruits, through complexation of tannins and proteins. Our values have been relatively equivalent compared to many other fruits of different families present in Cerrado ecosystem (Rocha et al, 2011).…”

“…Several studies that included the species of Annona report excellent antioxidant activity, such as, the leaves of A. dioica (Formagio et al, 2013); leaves, bark, roots, and seedcake of A. squamosa (Baskar et al, 2007;Mariod et al, 2012;Shirwaikar et al, 2004); pulp, seeds, and peel of A. crassiflora (Roesler et al, 2006;; bark and leaves of Annona salzmannii (Costa et al, 2011(Costa et al, , 2012a; leaves of A. reticulata and A. muricata (Baskar et al, 2007;Melo et al, 2010); leaves of A. senegalensis (Ajboye et al, 2010); leaves of A. pickelii (Costa et al, 2011);and leaves of A. vepretorun (Costa et al, 2012b).…”

The antioxidant potential of fruit pulp and seeds of extracts of the Annona coriacea, and A. sylvatica (Annonaceae) were investigated, as well contents total phenolics, flavonoids, condensed tannins and ascorbic acid. Was used to determine the antioxidant activity the 1,1-diphenyl-1-picrylhydrazyl free radical (DPPH), β-carotene bleaching and ABTS radical cation method. The total phenol, total flavonoid, condensed tannin, and ascorbic acid contents were measured spectrophotometrically. In this study, the pulp and seeds of the fruits were extracted using methanol/water (8:2) for maceration. The seed extracts of A. coriacea demonstrated a moderate antioxidant effect with free radical scavenging activity of 31.53%, by the DPPH test, 51.59% by the β-carotene bleaching test and 159.50 µM trolx/g of extract in the ABTS assay. We found that the hydromethanolic seed extract of A. coriacea had high total phenol (147.08 ± 4.20 mg of GAE/g of extract) and flavonoid (131.18 ± 2.31 mg of QE/g of extract) content. This indicated that the antioxidant activity of the extracts was related to the contents of these constituents.Keywords: Annona, antioxidant activity, phytochemistry. Conteúdo

“…The highest means, with values ranging from 53.2 to 38.5 mg 100 g -1 , occurred with genotypes J7-02, 109, 102, 4, 42, 1, 108, 7, 57, 162, 47, 112, and 5 (Table 5). Higher contents of phenolic compounds have been found in fruits of guava (Psidium guajava) (83.0 mg 100 g -1 ) (Kuskoski, Asuero, Morales, & Fett, 2006) and gabiroba (259-285 mg 100 g -1 ) (Rocha et al, 2011) when compared to those found in the present study, despite fruits of jabuticaba trees belonging to the same botanical family. Such averages of total phenols obtained in this study in both years reinforces what has been described for flavonoids: despite the lower values of the sensorial quality of fruits harvested in 2013, these fruits tended to have higher biochemical means, with the exception of anthocyanins.…”

ABSTRACT. Nationally known in Brazil, the jabuticabeira or jabuticaba tree produces fruits of wide commercial acceptance. However, little use of jabuticaba in commercial orchards and large genetic erosion of jabuticaba caused by human activities in its habitats have been historically observed. Thus, the goal of this study was to characterize fruits of the jabuticaba tree (Plinia cauliflora) in a forest fragment maintained in southwestern Paraná State in an attempt to identify trees with superior fruits for future selection as cultivars or male genitors. To this end, 15 variables linked to sensory and biochemical characteristics of harvested fruits were analysed during two years of production. Twenty percent of the genotypes that showed the highest frequency of superiority in the evaluated characteristics were preselected for analysis. The quality of the analysed fruits indicated their potential for use. Thus, this work resulted in the preselection of jabuticaba genotypes 7, 42, 43, 47, 54, 91, 97, 104, 105, 118, 134, 153, 154, 157, 163, 169, 177, 186, 212, J7-01, and J7-02, with 16 and 194 the only genotypes that had already been selected for superior characteristics during both growing cycles.Keywords: Myrtaceae, phenotypic variability, biochemical characteristics. Aspectos de qualidade sensorial e nutracêutica de frutos de Plinia caulifloraRESUMO. Nacionalmente conhecida, a jabuticabeira possui frutos de ampla aceitação comercial. Todavia, o que se viu historicamente foi a pouca utilização da mesma em pomares comerciais e a ampla erosão genética ocorrida pela ação antrópica em seus habitats. Dessa forma, o objetivo deste trabalho foi caracterizar frutos de jabuticabeiras (P. cauliflora) de fragmento florestal mantido no sudoeste do Estado do Paraná, buscando-se identificar aquelas denominadas superiores para seleção como futuro cultivar ou genitor masculino. Para tal, foram analisadas 15 variáveis ligadas as características sensoriais e bioquímicas que os frutos colhidos apresentaram durante dois anos de produção. Como critério de pré-seleção foi adotada a escolha de 20% dos genótipos que apresentaram a maior frequência de superioridade nas características avaliadas. A qualidade das frutas analisadas demonstrou potencialidade para uso. Dessa forma, o presente trabalho permitiu pré-selecionar as jabuticabeiras 7, 42, 43, 47, 54, 91, 97, 104, 105, 118, 134, 153, 154, 157, 163, 169, 177, 186, 212, J7-01 e J7-02, sendo a 16 e 194 as únicas que já podem ser selecionadas pelas características de superioridade entre ambos ciclos.Palavras-chave: Myrtaceae, variabilidade fenotípica, características bioquímicas.

“…The largest quantity of phenolic idioblasts occurred among the analyzed samples of A. aculeata and A. totai (Table 3 and Figure 8 e, f). Phenolic compounds have antimicrobial activity and exert action against herbivory (Rocha et al, 2011b;Swain, 1959).…”

The genus Acrocomia (Arecaceae) is widely distributed in the Neotropics, without consensus on the number of species. The arboreal species are explored in their native countries. To subsidize better use of the observed variation in fruits of different species for product extraction, taxonomy, conservation and genetic improvement, our objective was to characterize biometrically the fruits and anatomically the mesocarp from natural populations of A. aculeata, A. intumescens and A. totai. We observed different colors of epicarp and mesocarp in A. aculeata and A. totai, while the fruits of A. intumescens were light green or yellowish. The fruits of A. aculeata showed diameter considered large (3.9-4.6 cm) and the highest dry mass (26.3-33.5 g), A. intumescens presented intermediate diameter (3.1-3.9 cm) and mass (11.5-18.8 g), and A. totai had the smallest diameter (2.2-3.0 cm) and mass (4.1-11.4 g). The morphoanatomical analysis of the mesocarp did not distinguish the three species. However, it revealed the presence of useful compounds for human consumption and with economic potential, such as oil in the parenchyma cells, mucilage, starch and phenolic compounds. We concluded that the mesocarp anatomy is not useful for taxonomy, but the biometric variation is, as well as variation within species can be applicable in conservation and genetic improvement.Keywords: biofuel, palm, plant anatomy, plant products, plant taxonomy ResumoO gênero Acrocomia (Arecaceae) é amplamente distribuído no continente americano não havendo consenso sobre o seu número de espécies, sendo as de porte arbóreo comercialmente exploradas nos países onde ocorrem. Com intuito de gerar subsídios para melhor aproveitar a variação observada nos frutos das diferentes espécies para taxonomia, conservação e melhoramento genético das espécies, o objetivo do presente estudo foi caracterizar biometricamente os frutos e anatomicamente o mesocarpo de populações naturais de A. aculeata, A. intumescens e A. totai. Foram observadas diferentes colorações de epicarpo e do mesocarpo em A. aculeata e A. totai, enquanto os frutos de A. intumescens são verde-claros ou amarelados. Os frutos de A. aculeata têm diâmetro considerado grande (3,9-4,6 cm) e de maior massa seca (26,3-33,5 g), A. intumescens apresentou diâmetro e massa intermediários dos seus frutos (3,1-3,9 cm e 11,5-18,8 g, respectivamente). A. totai apresentou os menores diâmetro e massa de frutos (2,2-3,0 cm e 4,1 -11,4 g, respectivamente). A análise morfoanatômica do mesocarpo não diferenciou as espécies do estudo. No entanto, revelou a presença de compostos úteis para consumo humano e potencial econômico dos compostos identificados, como a presença de óleo nas células do parênquima, mucilagem, amido e compostos fenólicos. Conclui-se que a anatomia do mesocarpo não é útil para taxonomia e que variação biométrica entre as espécies pode ser empregada para este fim, assim como a variação dentro das espécies pode ser útil para fins de conservação e melhoramento genético.
