The major goal of this research work was to use the dry extract of the fruits of Jussara palm tree (Euterpe edulis Martius) in the development of a tinting shampoo (0.3% (w/v) anthocyanin extract) and an exfoliating beauty cream integrating granules from the seeds of the fruit (1%, w/v). The dry extract was characterized via determination of the content of anthocyanins by the differential pH method, antioxidant activity by the phospho-molybdenum complex methodology, and antimicrobial activity by the disc-diffusion method. The extraction yield was 2.3% (w/w) (2.25 g dry extract/100 g fruit), with an antioxidant activity of 139.0 ± 5.5% relative to that of ascorbic acid, indicating a high antioxidant capacity. The anthocyanin extract did not exhibit antimicrobial activity. The physico-chemical stability characteristics of both the tinting shampoo and the exfoliating cream were evaluated via accelerated stability studies at 0, 30, 60 and 90 days of storage at 40 ± 2 °C and 75 ± 5% relative humidity. The cosmetic products prepared were stable in relation to the physico-chemical characteristics under the conditions studied.

The pulp of jussara açaí (Euterpe edulis Martius) fruit is rich in anthocyanins that exert antioxidant and anti-inflammatory effects similar to those exerted by aerobic exercise. In the present study, we investigated the effects of jussara açaí fruit pulp consumption, either alone or in combination with aerobic exercise, on the hepatic oxidative and inflammatory status of ApoE-deficient (ApoE− / −) mice. Male mice were divided into four groups (control (C), control plus açaí, exercise plus açaí (EXA) and exercise (EX)) and fed the AIN-93M diet or the AIN-93M diet formulated to contain 2 % freeze-dried açaí pulp. Mice in the EX and EXA groups were subjected to a progressive running programme (5 d/week, 60 min/d, 16 m/min) for 12 weeks. Mice that were made to exercise exhibited reduced (40·85 %; P< 0·05) hepatic superoxide dismutase activity when compared with the C mice, independent of the açaí diet. Mice in the EX group exhibited a lower (42 %; P< 0·05) mRNA expression of monocyte chemotactic protein-1 in the liver compared with the C mice. Mice in the EXA and EX groups had lower percentages of hepatic lipid droplets (70 % and 56 %, respectively; P< 0·05) when compared with the C mice. Mice in the EX group had smaller (58 %; P< 0·05) area of lesions in the aorta when compared with the C mice. Serum lipid profile was not affected (P>0·05). In conclusion, aerobic exercise training rather than açaí fruit pulp consumption or a combination of both enhances the hepatic oxidative and inflammatory status of ApoE− / − mice.

Jussara (Euterpe edulis) fruit is a strong candidate for exportation due to its high content of anthocyanins. However, its rapid perishability impairs its potential for further economic exploration, highlighting the relevance of producing ready-to-drink juices by applying innovative processing, such as high hydrostatic pressure (HHP). The effect of HHP (200, 350, and 500 MPa for 5, 7.5, and 10 min) on anthocyanins content and antioxidant activity (AA) by FRAP and TEAC assays, and the most effective HHP condition on overall sensory acceptance and stability of jussara juice, were investigated. While mild pressurization (200 MPa for 5 min) retained anthocyanins and AA, 82% of anthocyanins content and 46% of TEAC values were lost at the most extreme pressurization condition (500 MPa for 10 min). The addition of 12.5% sucrose was the ideal for jussara juice consumer acceptance. No significant difference was observed for overall sensory acceptance scores of unprocessed (6.7) and HHP-processed juices (6.8), both juices being well-accepted. However, pressurization was ineffective in promoting the retention of anthocyanins and AA in jussara juice stored at refrigeration temperature for 60 days, probably due to enzymatic browning.

A polpa de juçaí, fruto da palmeira juçara (Euterpe edulis Martius) encontrada nas áreas da Mata Atlântica e a polpa de açaí, fruto da palmeira juçara (Euterpe oleracea Martius) cultivado na Floresta Amazônica, foram caracterizadas obtendo assim sua composição centesimal, mineral e também seu teor de antocianinas. Com os resultados obtidos foi possível fazer um estudo comparativo da concentração de antocianinas das duas polpas congeladas e verificar a importância do consumo destes alimentos, classificados como funcionais, devido às propriedades antioxidantes de suas antocianinas no combate dos radicais livres no organismo humano.

A presente pesquisa objetivou a caracterização dos efeitos da altitude sobre o crescimento do Palmiteiro (Euterpe edulis). Para tanto foram definidas dez unidades amostrais ao longo de um gradiente de altitude, distribuídas sistematicamente com intervalos de 500 metros em um morro na formação Rio das Cobras com um raio com de aproximadamente 1500 m de extensão e com uma variação de 500 m na altitude. Para avaliação do Palmiteiro no gradiente altimétrico foram abatidos oito indivíduos de cada nível altimétrico, dos quais foram coletados os dados de biomassa total e a biomassa do creme comestível. Quando comparados os resultados encontrou-se tendências entre a produção de biomassa total e do creme em relação ao gradiente altitudinal. O SIG foi construído para retornar os valores de biomassa total e do creme e a densidade dos indivíduos na área, o que proporcionara informações para o planejamento florestal. QUANTIFICATION AND EVALUATION OF QUALITATIVE AND QUANTITATIVE PARAMETERS OF PALMITEIRO (Euterpe edulis MARTIUS) ALONG OF A ALTIMETRIC GRADIENT UISNG GEOGRAPHIC INFORMATION SYSTEM. Abstract The present research aimed the characterization of effects of altitude on growth of Palmiteiro (Euterpe edulis). It was defined ten sample plots, systematically distributed with 500m intervals, covering all gradient in the mound belongs to formation called Rio das Cobras with 500 m altitude. For the evaluation of the Palm in the studied area it was cut eight trees in each established level of altitude. The collected data were total biomass and biomass of eatable part. When compared the results it was find tendency between total biomass production and eatable part in relation to altitude gradient. The GIS was construct to find the values of total biomass and eatable part and the tree’s density in the area . The GIS will give important information to the forest management.
