“…Similar results are found in the literature, 9,39 and higher concentrations found for the fruit of the same family as jambo (Syzygium jambos) and araçá-boi (Eugenia stipitata). 4 The concentration of calcium in the fruit is much lower when compared with dairy products, but compared to other conventional fruits is what is closest to everyday values recommended by the Ministry of Health, which are for adults: 800 mg; infants: 400-600 mg; pregnant: 1,200 mg and children: 800-1,200 mg.…”

“…Copper was the studied mineral of lower concentration in the fruit pulp, which is consistent with values reported in the literature, 39 such higher concentrations to those found in acerola (Malpighia emarginata), 9 but are lower than those set by the World Health Organization as safe limit of your daily intake.…”

“…8 The mineral content in the fruits of camu-camu can supply adequate intake of mineral elements, as they have significant concentrations of potassium, calcium, magnesium, sodium, zinc, iron, manganese, copper, aluminum, and others that are present in fruit and can participate in the diversification of food sources. 9 Genetic diversity has been defined as the number of species within an ecosystem as well as the existing level of genetic variability within populations. 10 The analysis of physical, physicochemical, mineral and nutritional parameters of food has been used as a useful tool to identify the quality and/or select genotypes whose interaction with the environment is more favorable and efficient, since in folk medicine and the pharmaceutical industry is increasing the use of products from fruits, for its various pharmacological properties and are of great interest from the industrial processing sector due to its taste, aroma and yield squash, characterizing them as good sources of energy, carbohydrates, vitamins, minerals and products with bioactive properties, in addition to providing flavor and variety to the diet.…”

Due to the economic potential of camu-camu, considering its high concentration of vitamin C, the aim of this work was to evaluate the quality and genetic variability seven accessions of camucamu conserved in genebank (BAG) of Embrapa Amazônia Oriental, in the state of Pará, Amazon region, Brazil. The fruits of camucamuzeiro were analyzed for physicochemical characterization (standard methodologies) and mineral composition. The data were subjected to multivariate statistical analysis, using the techniques of cluster analysis and principal component analysis. The formation of different groups for each genotype, which shows the genetic variability and the dissimilarity of the genotypes in the species data, may be used to guide the selection of promising genotypes to enrich the programs of genetic improvement of the camucamuzeiro. Ascorbic acid showed levels above 1000 mg 100 g -1 , however, genotypes 4, 1 and 2 show the highest potential and the most promising nutritional capacity, but genotype 4 showed good characteristics for the moisture, acidity, carbohydrates, Cu and Zn and differs totally from others about the total soluble solids (TSS) and flavon-3-ol, features that make it the most promising genotype. It was possible to separate the seven different genotypes using multivariate analysis (hierarchical cluster analysis-HCA and principal component analysis-PCA).

“…O camu-camu é um fruto amazônico que vem despertando grande interesse devido a seu teor nutricional 5 . Recentemente, ganhou notoriedade por sua elevada concentração de ácido ascórbico 6 e, além disso, também é fonte de minerais e flavonoides, como a quercetina 7,8 .…”

“…As concentrações de minerais encontradas no suco de camu-camu (Tabela 1) diferem das concentrações obtidas por Yuyama et al 7 , os quais analisaram amostras de frutos provenientes das margens do Rio Uatumã. Entretanto, os diferentes tipos de cultivo, terra firme e regiões alagadas ou de várzea podem alterar as características nutricionais do fruto, pois diferenças no solo acarretam alterações morfológicas nos espécimes, o que possivelmente justificaria as diferentes concentrações minerais nos frutos 21 .…”

Este estudo teve como objetivo avaliar o potencial hipolipidêmico do suco de camu-camu (Myrciaria dubia (Kunth) McVaugh) em ratos dislipidêmicos. MétodosForam utilizados 72 ratos (Rattus norvegicus var. albinus) machos adultos da linhagem Wistar, com peso médio de 200g. O experimento foi dividido em duas fases: indução da dislipidemia e tratamento. Para indução da dislipidemia, todos os ratos receberam ração hiperlipídica (ração comercial adicionada a 10,0% de banha suína, 1,0% colesterol e 0,1% de ácido cólico) durante 21 dias. Na fase de tratamento, 40 ratos dislipidêmicos foram divididos aleatoriamente em 5 grupos (n=8), sendo 3 deles submetidos a tratamento com diferentes concentrações de suco de camu-camu (0,4mL.kg -1 , 4,0mL.kg -1 e 10mL.kg -1 ) por 14 dias, 1 grupo submetido a tratamento com quercetina (10mL.kg -1 ) e 1 grupo hiperlidêmico. Estes dois últimos foram mantidos como parâmetro, ao lado do grupo basal. Para avaliar o efeito modulador do suco de camu-camu no perfil lipídico dos ratos, foram verificadas as concentrações de triacilgliceróis, colesterol total, lipoproteína de alta intensidade e lipoproteína de baixa intensidade, no plasma, assim como os níveis de colesterol fecal e hepático. Também foram observados o controle da ingestão de ração e a avaliação da massa corporal. ResultadosAs diferentes doses de suco de camu-camu e de quercetina apresentaram efeitos moduladores do perfil lipídico, ou seja, redução de triacilgliceróis, colesterol total, excreção fecal de colesterol, bem como redução do colesterol hepático. Salienta-se que os melhores resultados foram obtidos com a concentração de 10mL.kg -1 . Em relação

Camu-camu is a shrub, native to the Amazon that thrives in areas where flooding is frequent. Genetically, the plant is characterized by a diploid genome and moderate genetic diversity. Several parts of the plant are used in traditional folk medicine to treat a variety of acute and chronic diseases. For over 50 years, the exceptionally high vitamin C content of camu-camu has attracted worldwide attention that continues today because of the recent discovery of several healthpromoting phytochemicals with corroborated biological activities (e.g., antioxidant, anti-obesity, antidiabetic). All of these beneficial attributes are well supported by in vitro and in vivo studies as well as human clinical trials. The metabolic precursors of these phytochemicals are synthesized in key metabolic pathways (i.e., the shikimate pathway, the mevalonate pathway). Of these metabolic pathways, we show details for the biosynthesis of betulinic acid, transresveratrol, and syringic acid. In conclusion, camu-camu is an exceptional plant for its ability to produce and accumulate significant amounts of a variety of health-promoting phytochemicals. Although several metabolic pathways responsible for the biosynthesis of these phytochemicals have been reconstructed based on fruit and seedling transcriptomes, detailed knowledge of the vast majority of metabolic pathways and their molecular regulatory mechanisms is lacking. Consequently, we must increase our knowledge of the metabolic processes using multi-omic approaches so that we can acquire the skills necessary to develop genetically improved varieties of camu-camu and implement biotechnological applications for the production of these bioactive phytochemicals.
