“…These results are in accordance with the fatty acid profiles obtained in the present study, since the major triglycerides obtained were formed by palmitic, oleic, and linoleic acids. The use of triglyceride profile prediction has also been reported by other authors and the compositions obtained are quite similar to those obtained experimentally [ 22 , 66 , 67 ]. All triglycerides identified can be classified as long-chain triglycerides (LCT), since they have more than 36 carbon atoms.…”

The use of clean technologies in the development of bioactive plant extracts has been encouraged, but it is necessary to verify the cytotoxicity and cytoprotection for food and pharmaceutical applications. Therefore, the objective of this work was to obtain the experimental data of the supercritical sequential extraction of murici pulp, to determine the main bioactive compounds obtained and to evaluate the possible cytotoxicity and cytoprotection of the extracts in models of HepG2 cells treated with H2O2. The murici pulp was subjected to sequential extraction with supercritical CO2 and CO2+ethanol, at 343.15 K, and 22, 32, and 49 MPa. Higher extraction yields were obtained at 49 MPa. The oil presented lutein (224.77 µg/g), oleic, palmitic, and linoleic, as the main fatty acids, and POLi (17.63%), POO (15.84%), PPO (13.63%), and LiOO (10.26%), as the main triglycerides. The ethanolic extract presented lutein (242.16 µg/g), phenolic compounds (20.63 mg GAE/g), and flavonoids (0.65 mg QE/g). The ethanolic extract showed greater antioxidant activity (122.61 and 17.14 µmol TE/g) than oil (43.48 and 6.04 µmol TE/g). Both extracts did not show cytotoxicity and only murici oil showed a cytoprotective effect. Despite this, the results qualify both extracts for food/pharmaceutical applications.

“…Assaí, acaí or açaí, is a berry-like fruit rich in natural antioxidants, phenolic compounds and vitamins ( Aliaño-González et al, 2020 , Machado et al, 2019 , Silva et al, 2019 ). Responsible for its light- to purple-color variations, anthocyanins are the major polyphenols found in açaí.…”

“…They suggested that regular açaí intake can positively influence endogenous antioxidant processes, thereby protecting cells from oxidative damage. Moreover, açaí consumption can affect lipid metabolism, displaying beneficial effects on LDL-c and HDL-c control ( Aliaño-González et al, 2020 , Liz et al, 2020 , Machado et al, 2019 , Magalhães et al, 2020 , Silva et al, 2019 , Silva et al, 2020 , Souza et al, 2020 ). Furthermore, when studying the biological properties of the açaí oil, several researchers found a powerful in vitro antioxidant activity from it as well as a great content of phenolic compounds non-anthocyanins, which could be potentialized when encapsulated into micro- or nanoparticles to a controlled release in specific targets ( Pacheco-Palencia et al, 2008 , Rufino et al, 2011 , Teixeira-Costa et al, 2020 ).…”

“…On the other hand, it can also grow in dry lands in low-density forests. The moist soil and the high light intensity, due to the limited vegetation cover in lowland soils, are favorable to the development of hydrophilic vegetation species such as açaí [ 42 , 43 , 44 ]. The fruiting of açaí occurs in all seasons of the year, mainly between the months of July and December when the humidity is lower in the Amazon region [ 45 ].…”

Nutritional Composition and Bioactive Compounds of Native Brazilian Fruits of the Arecaceae Family and Its Potential Applications for Health Promotion

et al. 2022

The fruits from the Arecaceae family, although being rich in bioactive compounds with potential benefits to health, have been underexplored. Studies on their composition, bioactive compounds, and effects of their consumption on health are also scarce. This review presents the composition of macro- and micronutrients, and bioactive compounds of fruits of the Arecaceae family such as bacaba, patawa, juçara, açaí, buriti, buritirana, and butiá. The potential use and reported effects of its consumption on health are also presented. The knowledge of these underutilized fruits is important to encourage production, commercialization, processing, and consumption. It can also stimulate their full use and improve the economy and social condition of the population where these fruits are found. Furthermore, it may help in future research on the composition, health effects, and new product development. Arecaceae fruits presented in this review are currently used as raw materials for producing beverages, candies, jams, popsicles, ice creams, energy drinks, and edible oils. The reported studies show that they are rich in phenolic compounds, carotenoids, anthocyanins, tocopherols, minerals, vitamins, amino acids, and fatty acids. Moreover, the consumption of these compounds has been associated with anti-inflammatory, antiproliferative, antiobesity, and cardioprotective effects. These fruits have potential to be used in food, pharmaceutical, and cosmetic industries. Despite their potential, some of them, such as buritirana and butiá, have been little explored and limited research has been conducted on their composition, biological effects, and applications. Therefore, more detailed investigations on the composition and mechanism of action based on in vitro and/or in vivo studies are needed for fruits from the Arecaceae family.
