RESUMO As frutas fornecem não somente nutrientes essenciais à alimentação, mas também compostos bioativos que promovem benefícios à saúde e auxiliam na redução do risco de desenvolvimento de doenças crônicas não transmissíveis. Neste mesmo sentido, o presente trabalho objetivou quantificar os compostos bioativos durante a maturação de quatro frutas nativas da Restinga cearense. Os frutos da murta (Eugenia punicifolia (Kunth) DC.) foram colhidos no Parque Estadual Botânico do Ceará, em Caucaia-CE, e os do guajiru (Chrisobalanus icaco L.), do manipuçá (Mouriri cearensis Huber) e do murici-pitanga (Byrsonima gardneriana A. Juss.) no Jardim Botânico de São Gonçalo, em São Gonçalo do Amarante–CE. Os frutos foram coletados em diferentes estádios (E) e transportados ao Laboratório de Ecofisiologia Vegetal, sendo caracterizados em cinco ou seis estádios de maturação, de acordo com a coloração da casca, depois processados e congelados para as avaliações físico-químicas e químicas: ácido ascórbico, clorofila total, carotenoides totais, antocianinas totais e flavonoides amarelos. Utilizou-se do delineamento inteiramente casualizado, com cinco ou seis tratamentos, dependendo dos estádios de maturação do fruto, e quatro repetições. O fruto do murici-pitanga foi superior para ácido ascórbico (646,23 mg ácido ascórbico/100 g no E5), carotenoides totais (6,13 mg/100 g no E5) e antocianinas totais (7,99 mg/100 g no E2); e o fruto da murta foi superior para clorofila (11,05 mg/100 g no E1) e flavonoides amarelos (69,11 mg/100 g no E2). Existem correlações positivas e significativas entre clorofila e carotenoides (R= 0,99; P < 0,01) para o manipuçá, e entre antocianina e flavonoides amarelos (R= 0,97; P < 0,05) para o murici-pitanga; no entanto, a correlação é negativa e significativa entre ácido ascórbico e flavonoides amarelos (R= -0,98; P < 0,05) na murta. Conclui-se que o murici-pitanga e a murta têm os maiores números de compostos bioativos com os níveis mais altos; portanto, ambos os frutos podem ser recomendados para serem explorados comercialmente pelos setores de alimentação, cosméticos e fitoterápicos.

ABSTRACT Fruits provide not only essential nutrients for food, but also bioactive compounds that promote health benefits and help reducing the risk of developing non-communicable chronic diseases. In this sense, this work aimed at quantifying bioactive compounds during the maturation of four fruits native to the Restinga forest of Ceara. Myrtle fruits (Eugenia punicifolia (Kunth) DC.) were collected at the Botanical State Park of Ceara, Caucaia-CE, and guajiru (Chrisobalanus icaco L.), manipuça (Mouriri cearensis Huber) and murici-pitanga fruits (Byrsonima gardneriana A. Juss.) at the Botanical Garden of São Gonçalo, São Gonçalo do Amarante-CE. Fruits were collected at different stages (E) and transported to the Laboratory of Plant Ecophysiology, being characterized into five or six maturation stages according to the bark color, then processed and frozen for the following physicochemical and chemical evaluations: ascorbic acid, total chlorophyll, total carotenoids, total anthocyanins and yellow flavonoids. A completely randomized design was used, with five or six treatments, depending on the maturation stages of fruits and four replicates. Murici-pitanga had higher contents of ascorbic acid (ascorbic acid 646.23 mg/100 g E5), total carotenoids (6.13 mg/100 g E5) and total anthocyanins (7.99 mg/100 g E2); and myrtle had higher contents of total chlorophyll (11.05 mg/100 g E1) and yellow flavonoid (69.11 mg/100 g E2). There are positive and significant correlations between chlorophyll and carotenoid (R= 0.99; P <0.01) for manipuça and between anthocyanin and yellow flavonoid (R= 0.97; P <0.05) for murici-pitanga fruits; however, the correlation is negative and significant between ascorbic acid and yellow flavonoids (R= -0.98; P <0.05) for myrtle fruits. It could be concluded that murici-pitanga and myrtle fruits had the highest contents of bioactive compounds with the highest levels, therefore both fruits can be recommended to be commercially exploited by the food, cosmetic and phytomedicine sectors.

The aim of the present study was to evaluate the effect of cotrimoxazole on the in vitro susceptibility of Coccidioides posadasii strains to antifungals. A total of 18 strains of C. posadasii isolated in Brazil were evaluated in this study. The assays were performed in accordance with the Clinical and Laboratory Standards Institute guidelines and the combinations were tested using the checkerboard method. The minimum inhibitory concentrations were reduced by 11, 2.4, 4.3 and 3.5 times for amphotericin B, itraconazole, fluconazole and voriconazole, respectively. Moreover, it was seen that cotrimoxazole itself inhibited C. posadasii strains in vitro. The impairment of folic acid synthesis may be a potential antifungal target for C. posadasii.
