Eugenia punicifolia (Kunth) DC. is a medicinal plant used to treat diseases related to oxidative processes. In this work, H-1 nuclear magnetic resonance (NMR) spectroscopy and multivariate analysis have been employed to track the chemical changes and antioxidant activity of dimethyl sulfoxide (DMSO) extracts from E. punicifolia leaves over seasons. Principal component analysis (PCA) applied to H-1 NMR allowed discriminating DMSO extracts from leaves collected in the dry and rainy seasons and pointed out sucrose, catechin, and epicatechin as responsible for separating dry season samples and quercetin, acid gallic, glucose, and fatty acids contributed for rainy samples grouping. Notably, antioxidant assays revealed that dry season extracts exhibited a higher... |

As folhas de Myrcia multiflora (Lam.) DC, Myrcia guianensis (Aubl.) Urb. e Eugenia punicifolia (H. B. K.) DC. são anatômica c morfologicamentc descritas. As espécies revelaram diversos elementos histológicos universais para a família, bem como peculiares das mesmas e importantes para orientar a diagnose desses vegetais e para o reconhecimento de fraudes, que ocorrem através de substituições intencionais ou não. Entre os elementos histológicos característicos, destacam-se: ornamentações de cutícula foliar, tipos de estômatos, tipos de contornos celulares das células epidérmicas em vista facial, tipo e abundância relativa de inclusões celulares inorgânicas. |

ABSTRACT This study aimed to evaluate the physico-chemical composition of native fruits of the Ceará coast at different development stages. The fruits of ‘guajiru’, ‘manipuçá’, ‘murici-pitanga’ and ‘murta’ were collected during the year 2014, and the following evaluations were made: total soluble solids, total titratable acidity, pH, total soluble solids and titratable acidity ratio. A completely randomized design was used, with 5 or 6 treatments, depending on the maturation stage and 4 replicates. For total soluble solids, ‘murta’ obtained a minimum of 2.6 °Brix in stage 1 and ‘manipuçá’ obtained maximum of 24.53 °Brix in stage 5. For the total titratable acidity, ‘guajiru’ showed minimum of 0.09% in stages 3 and 4, and ‘murici-pitanga’ showed maximum of... |
