Composition, content of bioactive compounds, and antioxidant activity of fruit pulps from the Brazilian Amazon biome

Abstract

The objective of this work was to evaluate the physicochemical composition, the bioactive compounds, and the total antioxidant activity of the fruit pulps of abiu (Pouteria caimito), achachairu (Garcinia humilis), araza (Eugenia stipitata), bilimbi (Averrhoa bilimbi), and yellow mangosteen (Garcinia xanthochymus) from the Brazilian Amazon biome. Total soluble solid content, total and reducing sugar contents, titratable acidity contents, pH, ascorbic acid content, moisture, protein, lipid, ash, and caloric value were determined. The contents of total anthocyanins, yellow flavonoids, and total carotenoids, besides total phenolic compounds and antioxidant activity, were also evaluated. The abiu pulp showed the highest contents of ash, total sugars, reducing sugars, total soluble solids, calorie value, and pH, among the analyzed fruits. The achachairu pulp showed the highest content of total phenolic compounds, with significant antioxidant activity, while the araza pulp had the highest total carotenoid content, and the yellow mangosteen, the highest yellow flavonoid content. The positive correlation between antioxidant activity and total phenolic compounds suggests that these compounds are the most important for determining antioxidant activity in the evaluated fruit pulps.

Predictive study of the Bioconcentration of Organochlorine Compounds by a QSPR Model

“…Despite the different extraction procedure and solvents used, as well as the environmental conditions which reflect strongly on the fruit phenolic composition, recently studies yielded close findings for total phenol contents in Brazilian abiu fruit from Rondônia, BR (172.3 mg GAE/100g fresh weight) [43] and from Roraima, BR (900.2 mg GAE/100g dry weight) [44] in comparison to our results (220.2 mg GAE/100g fresh weight or 779 mg GAE/100g dry weight). In another study, involving traditionally consumed palm fruits from Amapá, BR, the results after extraction steps involving acetone, methanol and water solvents, were higher to buriti (118±2 mg GAE/100g fresh weight) and lower to inajá (45±2 mg GAE/100g fresh weight) [45], considering our results in fresh weight 83.15 and 155.0 mg GAE/100g, respectively.…”

UPLC-QTOF-MS Analysis of Extracts from the Leaves of <i>Pouteria caimito</i> (Sapotaceae) and Their Antioxidant Activity

“…The fruits and leaves of P. caimito are used in folk medicine in the treatment of coughs, bronchitis and diarrhoea [11]. Some studies report the pharmacological potential of this species, such as antioxidant activity [12] and inhibition of α-amylase and β-glucosidase enzymes, which are therapeutic targets in the search for new drugs for the treatment of diabetes [13]. The phytochemical study of P. caimito is of great importance, since there are few reports in the literature involving this species.…”

Metabolite Profiling by UPLC-MSE, NMR, and Antioxidant Properties of Amazonian Fruits: Mamey Apple (Mammea Americana), Camapu (Physalis Angulata), and Uxi (Endopleura Uchi)

“…Some species such as mamey apple (Mammea americana), camapu (Physalis angulata), and uxi (Endopleura uchi) have widely appreciated flavors by Brazilian consumers, but still of moderate importance to the economy. They show potential for commercialization in both domestic and international markets [6].…”
