“…In percentage terms, the pulp, bark, and seed have mean values of 51.3%, 22.6%, and 26.1%, respectively. These results are very close to that early described [4,29]. By comparison, although the fruits have been collected in distinct areas of the Amazon (Pará and Amazonas states), it is observed that there are similar physical characteristics, which presupposes a homogeneity for the species.…”

Although the consumption of Amazonian fruits has a regional predominance, these fruits present great possibilities for their use in agroindustry. Also, scientific research that seeks to identify functional properties in fruits also promotes their commercial value and, as a consequence, can benefit family farming and contribute to the sustainable development of the region. The most significant challenge for the exploration and commercialization of new fruit species, particularly in the most distant and hard-to-reach areas is the preservation of their organoleptic characteristics and their nutritional value, given the prospect of high perishability during transport [13].Nowadays, the post-harvest loss of fruit in Brazil reaches 30%. These losses stem from the choice of inappropriate cultivars, improper postharvest techniques, poor transport conditions and inadequate storage for the products. On the other hand, there is a growing interest in processed fruits, both domestically and abroad the country, due to the demand for healthy foods that are convenient and ready for

“…Isto segue o padrão de outras fruteiras amazônicas, tais como araçá-pera (Psidium acutangulum; Falcão et al, 1992), umari (Poraqueiba sericea; Falcão & Lleras, 1980) e pajurá (Couepia bracteosa; Falcão et al, 1981).

RESUMO -O araçá-boi (Eugenia stipitata McVaugh ssp. sororia McVaugh, Myrtaceae) é uma frutífera nativa da Amazônia Ocidental com potencial para a indústria de sucos e flavorizantes. Embora pouco plantada na Amazônia brasileira devido a sua acidez, é frequentemente cultivada na Amazônia peruana. O conhecimento de sua fenologia pode ajudar no planejamento do manejo do plantio e da comercialização dos frutos. A fenologia de dez plantas, crescendo num latossolo amarelo degradado, foi observada durante cinco anos. O araçá-boi geralmente floresceu e frutificou três vezes ao longo do ano e sempre teve pelo menos um pico de floração forte durante a estação seca (julho a setembro) e um pico de frutificação mais acentuado na estação chuvosa (janeiro a março). A floração é um evento complexo e demorado que pode durar de dois a três meses, embora o período entre o aparecimento do botão floral até a antese do flor é curto (~15 dias) e o período entre a antese e a maturação dos frutos dura 50 a 60 dias. As regressões múltiplas usadas para determinar o efeito das variáveis climáticas na floração e frutificação não apresentaram altos coeficientes de determinação, embora os modelos tenham sido significantes, provavelmente porque o araçá-boi floresce várias vezes durante o ano e ainda não se sabe qual o estímulo mais importante para iniciar o processo. O vingamento dos frutos variou de menos de 5% a aproximadamente 15%. O peso médio dos frutos avaliados em janeiro de 1988 foi 135 g, com 77% de polpa. Ao longo do período, estimou-se que as dez plantas produziram cm média 1000 frutos/ano, com uma mediana de 890 frutos/ano. Os insetos visitantes eram principalmente abelhas, especialmente Apis mellifera, Eulaema mocsaryi e Ptilotrigona lurida.Palavras-chave: floração, frutificação, mudança foliar, vingamento, clima. Phenology and Yield of Araçá-boi (Eugenia stipitata, Myrtaceae) in Central AmazoniaABSTRACT -The araçá-boi (Eugenia stipitata McVaugh ssp. sororia McVaugh, Myrtaceae) is a small fruit species native to western Amazonia with international potential as a juice and cultivated in other countries. A knowledge of phenology can help plan plantation management and fruit commercialization. The phenology of ten plants growing in a degraded oxisol was year, with at least one strong flowering peak in the dry season (July-September) and a strong fruiting peak in the rainy season (January-March). Flower initiation is a complex event that short (~15 days) and the period from anthesis to fruit maturation takes between 50 and 60 days. The multiple regressions used to determine the effect of climatic variables on flowering and the araçá-boi flowers several times during the year and the most important stimulous for 1988 was 135 g, with 77% of pulp. During the 5 years, the 10 plants yielded 1000 fruits/year, with a median number of 890 fruits/year. Most of the insect visitors were bees, especially Apis mellifera, Eulaema mocsaryi and Ptilotrigona lurida.

“…Thus, enhancing the knowledge of the species, their chemical composition and their biological properties is one of the major challenges to improve their commercial value and rational exploitation. 7 To the best of our knowledge, no data related to the bioactive compounds or biological potential of C. bracteosa fruits have been published in the literature. [2][3][4][5] In biological systems, the production of ROS and RNS is important to maintain homeostasis.…”

Among the large number of scientifically unstudied fruits from the Amazonia biome, Couepia bracteosa acts as an interesting source of bioactive compounds, such as phenolic compounds and carotenoids, which may be used for protecting human health against oxidative damage. For the first time, the phenolic compounds and carotenoids in extracts obtained from the pulp, shell and seeds of C. bracteosa fruits are reported, as well as their in vitro scavenging capacities against some reactive oxygen species (ROS) and reactive nitrogen species (RNS). The shell extract presented the highest phenolic compound and carotenoid contents (5540 and 328 μg per g extract, dry basis, respectively), followed by the pulp and seed extracts. The major phenolic compound was acacetin sulphate (one methoxy and two OH groups) (62%) in the shells; however, only seeds presented apigenin sulphate (three OH groups), in which it was the major compound (44%). The high content of apigenin sulphate may explain why the seed extract had the highest scavenging efficiency against all tested ROS/RNS among the studied extracts. Regarding carotenoids, all-trans-neochrome (17%) and all-trans-β-carotene (16%) were the major carotenoids in the pulp extracts, while all-trans-lutein (44%) was the most prevalent in the shell extracts and all-trans-α-carotene (32%) and all-trans-β-carotene (29%) were the major ones in the seed extracts.
