Bioactive compounds of 44 traditional and exotic Brazilian fruit pulps: phenolic compounds and antioxidant activity

Abstract

Bioactive compounds and antioxidant activity from 44 fruit were evaluated. The data were statistically evaluated by analysis of common components and specific weights (CCSWA). Panã, acerola, açaí, and jabuticaba showed higher values of total phenolic compounds (TPCs) and antioxidant activity. The analysis of CCSWA was able to explain almost 100% of the variance of the data and established the correlation between TPC and antioxidant capacity, being the most influential variables in the classification of samples. This statistical method is ideal for quickly analyzing a large amount of data, as obtained in this research, which facilitates routines of industrial analysis.

Optimizing parameters on the antioxidant capacity of watermelon pulp using conventional orbital shaker and ultrasound‐assisted extraction methods

“…The highest TPC (55.27 mg) was extracted using COS extraction (100% methanol + 1% HCl) with sample‐to‐solvent ratio of 1:20. According to Stafussa et al., (2018) only fruit extracts (jatobá and watermelon) showed a low concentration of TPC, with 99.40 mg GAE/100 g for jatobá and 55.66 mg GAE/100 g for watermelon. Similar trends (55.66 mg) TPC was reflected by (Stafussa et al., 2018) study.…”

Moreover, the results of this study are comparatively higher in comparison to a relatively similar TPC study (Singh et al., 2016).…”

Phytochemical Screening and Antioxidant Potential of Aqueous Extracts of Millettia laurenti, Lophira alata and Milicia excelsa, Commonly Used in the Cameroonian Pharmacopoeia

“…That compound might be flavonoids as it showed the highest correlation with the total antioxidant capacity (r 2 = 1.00, P = .01) and the iron-reducing capacity (r 2 = 0.94, P = .22). It can, therefore, be suggested a quantitative dependence of TAC with flavonoids and tannins but rather a qualitative one (nature of the compounds) with polyphenols and alkaloids [33,40,41].…”

Avaliação físico-química e capacidade antioxidante do extrato de buriti (Mauritia flexuosa L.) e atividade antitumoral em linhagem celular de câncer de mama MDA-MB-231

“…Entre os principais compostos fenólicos, a catequina foi encontrada na maioria das polpas de frutas. Outros compostos importantes que também foram identificados corresponderam aos ácidos hidroxicinâmicos, ácidos hidroxibenzoicos e estilbeno (STAFUSSA et al, 2018). Quanto ao teor de carotenoides, a polpa de buriti apresentou o maior valor dentre os frutos brasileiros estudados, correspondendo a 2,85 mg / 100 g de licopeno e 4,65 mg / 100 g de β-caroteno (SCHIASSI et al, 2018).…”

Stafussa et al (2018), outros extratos de frutas que apresentam elevada capacidade antioxidante são acerola (DPPH• = 7433,37 μmol Trolox / 100 g; ABTS•+ = 8511,84 μmol Trolox / 100 g) e polpa de panã (DPPH• = 4486,11 μmol Trolox / 100 g;ABTS•+ = 4778,32 μmol Trolox / 100 g). Aqueles com maiores concentrações de compostos fenólicos totais são panã (902,18 mg GAE / 100 g), açaí (708,22 mg GAE / 100 g), jabuticaba (626,57 mg GAE / 100 g) e acerola (593,77 mg GAE / 100 g).…”
