Extração e caracterização qualitativa do óleo da polpa e amendoas de frutos de macaúba [Acrocomia aculeata (Jacq) Lodd. ex Mart] coletada na região de Botucatu - SP

The international energy situation indicates to the depletion of oil reserves in the short term. Brazil, considering its potential, has sought through public policy, encourage the study of alternative forms of energy. Many of these forms are based on sub-products and agricultural products, especially the ethanol industry for fuel purposes. Another alternative of vegetable origin, most recently discussed, would be the production of fuel oil called biodiesel. The study aimed to extract and measure the pulp oil production of macaúba palm [Acrocomia aculeata (Jacq) Lodd. ex Mart], collected in Botucatu (SP). In addition, the qualitative analysis of the pulp and almond oil are determined. The results showed low productivity in oils, compared to the reported for macauba natural populations of Minas Gerais. The qualitative analysis of the macauba pulp shows to be rich in long chain fatty acids, while the almond have significant amounts of lauric acid.

Caracterização morfológica, perfil químico, atividade biológica e conservação in situ do gênero Lychnophora Mart. (Asteraceae: Vernonieae: Lychnophorinae), Brasil

Many people who live in the cerrado regions use plant species for therapeutic purposes. However, due to intensive extraction of some species, native botanical populations are at risk of disappearing or suffering a dramatic decrease, such as, for instance, individuals of the Lychnophora genus. This has 24 species distributed into the categories vulnerable, endangered, critically endangered, and possibly extinct. These individuals are known in folk medicine as “arnica” and their leaves and flowers are commonly used as anti-inflammatory, analgesic, and healing agents. The chemical profile of the genus is characterized by the presence of sesquiterpene lactones, sesquiterpenes, diterpenes, triterpenes, flavonoids, steroids, polyacetylenes, and caryophyllene derivatives which also have lignans with analgesic activity. Studies with Lychnophora species show significant results with regard to their biological activities against Leishmania amazonensis, Staphylococcus aureus, and Tripanosoma cruzi. Therefore, this study aimed to perform a survey of the morphology, chemical composition, and biological activity, as well as the use and current conservation status of the Lychnophora genus in Brazil.

Ocorrências e usos do Tucumã (astrocaryum vulgare mart) em comunidades ribeirinhas, quilombolas e de agricultores tradicionais no município de Irituia, Pará

The aim of the study is to demonstrate the occurrence and usage of the Tucumã (Astrocaryum vulgare Mart.) in rural areas of the Municipality of Irituia, in the State of Pará (Brazil), since the use of the palm part of the traditional culture of communities of farmers, riparian and quilombola, used in curing diseases in human and domestic animals, building shelters, obtaining fibers, production of tools and crafts, hunting and fishing. In addition to the uses reported by the population, tucumã has potential for the production of oil and biodiesel. In this sense, the Federal University of Pará – UFPA, in a partnership with the Irituia’s Municipal Government, is studying the implementation of an oleaginous processing plant in the municipality, among them, and includes the Tucumã as a potential source. Such proposal stipulates the production in the agroforestry system, as an alternative to the slash and burn agriculture in the region, reconciling environmental conservation with territorial rural development. Considering the results obtained in the field, it has been found an average of 9.4 stumps per hectare, each stump having 7.7 stipes and 4.7 racemes with up to 146 fruits. If all the Tucumã’s stumps were kept until they reached their average productivity capacity, it is estimated that the fruit production in the rural area of the municipality would be around 132.060 tons, which could produce up to 12.665,4 tons/year of pulp oil and 4.768,4 tons/year of nut oil, confirming the supply of raw material to move this productive chain.

A new HPLC-DAD-MS/MS method for the simultaneous determination of major compounds in the crude extract of Lychnophora salicifolia Mart. (Brazilian arnicao) leaves: Application to chemical variability evaluation

Lychnophora salicifolia Mart., which occurs in the Brazilian Cerrado in the states of Bahia and Minas Gerais as well as in the southeast of the state of Goias, is the most widely distributed and also the most polymorphic species of the genus. This plant is popularly known to have anti-inflammatory and analgesic activities. In this work, we have studied the variation in terms of polar metabolites of ninety-three Lychnophora salicifolia Mart, specimens collected from different regions of the Brazilian Cerrado. Identification of the constituents of this mixture was carried out by analysis of the UV spectra and MS data after chromatographic separation. Twenty substances were identified, including chlorogenic acid derivatives, a flavonoid C-glucoside, and other sesquiterpenes. The analytical method was validated, and the reliability and credibility of the results was ensured for the purposes of this study. The concentration range required for analysis of content variability within the analyzed group of specimens was covered with appropriate values of limits of detection and quantitation, as well as satisfactory precision and recovery. A quantitative variability was observed among specimens collected from the same location, but on average they were similar from a chemical viewpoint. In relation to the study involving specimens from different locations, there were both qualitative and quantitative differences among plants collected from different regions of Brazil. Statistical analysis revealed that there is a correlation between geographical localization and polar metabolites profile for specimens collected from different locations. This is evidence that the pattern of metabolites concentration depends on the geographical distribution of the specimens. (C) 2012 Elsevier B.V. All rights reserved.
