“…(Rheedia brasiliensis Planch e Triana), belonging to the family Clusiaceae, commonly known as bacuri, bacupari, porocó and bacuripari, is a native of the Amazon region and having specimens spread throughout the Brazilian territory, being an important source of food for the fauna, as well as use as raw material for medicine (Oliveira, Ribeiro, Matias, Gusmão, & Pereira, 2011). Its therapeutic potential and its compounds provide multiple medicinal activities such as antianphylactic, antimicrobial, antispasmodic, anti-inflammatory, antioxidant, antiproteolytic, antiproliferative and leishmanicidal (Pereira et al, 2010;Santa-Cecília et al, 2013).…”

The objective of the present study was to test and establish mathematical models to estimate the leaf area of Garcinia brasiliensis Mart. through linear dimensions of the length, width and product of both measurements. In this way, 500 leaves of trees with age between 4 and 6 years were collected from all the cardinal points of the plant in the municipality of São Mateus, North of the State of Espírito Santo, Brazil. The length (L) along the main midrib, the maximum width (W), the product of the length with the width (LW) and the observed leaf area (OLA) were obtained for all leaves. From these measurements were adjusted linear equations of first degree, quadratic and power, in which OLA was used as dependent variable as function of L, W and LW as independent variable. For the validation, the values of L, W and LW of 100 random leaves were substituted in the equations generated in the modeling, thus obtaining the estimated leaf area (ELA). The values of the means of ELA and OLA were tested by Student’s t test 5% of probability. The mean absolute error (MAE), root mean square error (RMSE) and Willmott’s index d for all proposed models were also determined. The choice of the best model was based on the non significant values in the comparison of the means of ELA and OLA, values of MAE and RMSE closer to zero and value of the index d and coefficient of determination (R2) close to unity. The equation that best estimates leaf area of Garcinia brasiliensis Mart. in a way non-destructive is the power model represented by por ELA = 0.7470(LW)0.9842 and R2 = 0.9949.

“…Compostos lipídicos foram constatados apenas na cutícula da camada epidérmica de ambas as espécies analisadas. Compostos fenólicos, grãos de amido e idioblastos contendo drusas em abundância na estrutura foliar e pecíolo, são inclusões de grande importância para a caracterização das espécies, pois estão associadas a diversas atividades farmacológicas (SANTA-CECÍLIA et al, 2013).…”

RESUMO Embora Clusia fockeana Miq. e C. hoffmannseggiana Schltdl tenham eficácia comprovada no tratamento de diversas doenças, os possíveis sítios de produção das substâncias de ação terapêutica são praticamente desconhecidos. O objetivo do trabalho foi caracterizar a dinâmica de distribuição, tipos estruturais e as principais classes de compostos produzidos pelas estruturas secretoras presentes em folhas de Clusia fockeana e C. hoffmannseggiana, assim como descrever os estágios iniciais de desenvolvimento dos ductos secretores dessas espécies. Amostras foram coletadas na restinga do Crispim, PA, fixadas e processadas segundo técnicas usuais em microscopia de luz e eletrônica de varredura. Idioblastos, ductos e tecido paliçádico secretor são as estruturas secretoras presentes nas folhas de Clusia fockeana e C. hoffmannseggiana, exceto para o tecido paliçádico secretor que é exclusivo à C. Fockeana, e foi descrito pela primeira vez para o gênero Clusia. Tanino é a principal substância armazenada e/ou secretada pelos idioblastos e ductos. Ambas as espécies possuem ductos distintos em relação à distribuição, quantidade e diâmetro do lume. Estes são desenvolvidos no meristema fundamental do mesofilo e nervura central, através de processo esquizógeno. A distribuição das estruturas secretoras confere valor diagnóstico aos táxons analisados e contribui com dados inéditos para o melhor conhecimento das espécies em estudo e bioprospecção de seus compostos bioativos. PALAVRAS-CHAVE: Amazônia, bioprospecção, medicinal, tecido paliçádico secretor SECRETORY STRUCTURES IN Clusia fockeana MIC. AND Clusia hoffmannseggiana SCHLTDL. (CLUSIACEAE): DISTRIBUTION AND ANATOMY ABSTRACT Although Clusia fockeana Mic. and C. hoffmannseggiana Schltdl has proven efficacy in the treatment of various diseases, potential sites of production of the therapeutic action of substances are unknown. The goal of this study was to characterize the dynamic of distribution, structural types and the main classes of compounds produced by the secretory structures present in leaves of Clusia fockeana and C.

The aim of this work was to evaluate the effect of Salicylic acid, 2,4-D and 2-iP on the production of total phenolic and flavonoids as well in the levels of fukugetin and 7-epiclusianone in callus of Garcinia brasiliensis zygotic embryos. For this, Bacupari callus HIGHLIGHTS • Bacupari callus presents significative levels os phenolics and flavonoids.• Specifically, it was idenficated fukugetin e 7-epiclusianone • Growth regulators and salicylic acid affected the occurrence these substances.
