Phytochemical Compounds and Antioxidant Capacity of Tucum-Do-Cerrado (Bactris setosa Mart), Brazil’s Native Fruit

Abstract

This study identified major phenolic compounds of the tucum-do-cerrado (Bactris setosa) peel, as well as antioxidant activity and total phytochemical compound concentration of different extracts of the peel and pulp of this fruit. Phenolic compounds of the different extracts of tucum-do-cerrado peel were identified and quantified using a high-performance liquid chromatography system coupled to a diode array detector (DAD). Total phytochemical compound content was determined by spectrophotometric assays and the antioxidant activity by ferric reducing antioxidant power and β-carotene/linoleic assays. Total phenolic, flavanols, total anthocyanins and yellow flavonoids concentration of tucum-do-cerrado were 122-, 14-, 264- and 61-fold higher in the peel than in the pulp, respectively. The aqueous, methanolic and ethanolic extracts of the tucum-do-cerrado peel exhibited higher antioxidant activity compared to its pulp. Flavanols, anthocyanins, flavones, phenolic acids and stilbenes were the main phenolic classes identified in the tucum-do-cerrado peel extracts. Results suggest that the antioxidant capacity and the phytochemical compound content of the tucum-do-cerrado are mainly associated with the peel. Although flavonoids are the main compounds identified in tucum-do-cerrado peel, other phenolics identified in minor amounts, such as phenolic acids and stilbenes, may be responsible for the high antioxidant capacity of the fruit.

Tucum-do-Cerrado (Bactris setosa Mart.) May Promote Anti-Aging Effect by Upregulating SIRT1-Nrf2 Pathway and Attenuating Oxidative Stress and Inflammation

“…Tucum-do-cerrado ( Bactris setosa Mart. ), a Brazilian savanna fruit, has a high content of different phytochemical compounds such as cyanidin-derivatives, epicatechin, catechin, piceatannol, quercetin, and all- trans -lutein, mainly found in the peel [ 25 , 27 ] and a high antioxidant potential in vitro and in vivo [ 28 , 29 , 30 ]; however, many other potential biological effects still need to be investigated. Therefore, we hypothesized that the dietary consumption of tucum-do-cerrado ( Bactris setosa Mart.…”

Tucum-do-cerrado (Bactris setosa Mart.) modulates oxidative stress, inflammation, and apoptosis-related proteins in rats treated with azoxymethane

“…The lower levels of lipid oxidation (MDA) observed in the colon and liver of rats treated with tucum-do-cerrado associated with AOM (TU/DR) compared to the AOM treatment (CT/DR) may be related to the increased hepatic GST activity and to the high antioxidant capacity of tucum-do-cerrado, as previously described by Rosa, Arruda [ 41 ].…”

“…Tucum-do-cerrado is a native Brazilian fruit with a high phenolic compound content [ 41 ], therefore in this study we evaluated whether tucum-do-cerrado consumption has chemopreventive effects on the development of AOM-induced colon cancer in Wistar rats using indirect read outs markers for oxidative stress, inflammation and apoptosis. The tucum-do-cerrado ingestion by rats treated with AOM induced a decrease in levels of MDA and in an increase in levels of pro-inflammatory biomarkers, TNF-α and COX-2, and in levels of pro-apoptotic protein BAX.…”

Traditional Use of Palms (Arecaceae) in the Atlantic Forest in Southern Santa Catarina, Brazil

“…This practice of composing liqueurs with pulp of tucum fruits had already been reported in Santa Catarina state by Reitz (1974). Moreover, the fruit of tucum in natura is regarded as an important antioxidant (Fustinoni-Reis et al, 2016) because its bioactive compounds are mainly associated with the bark (pericarp) (Rosa et al, 2016).…”
