Brazilian Savanna Fruits Contain Higher Bioactive Compounds Content and Higher Antioxidant Activity Relative to the Conventional Red Delicious Apple

Abstract

The bioactive compounds content and the antioxidant activity (AA) of twelve fruits native to the Cerrado were compared with the Red Delicious apple by means of the antiradical efficiency (using the 2,2-diphenyl-1-picrylhydrazil assay/DPPH), ferric reducing antioxidant power (FRAP) and the β-carotene/linoleic system. The antiradical efficiency (AE) and the kinetic parameters (Efficient concentration/EC50 and time needed to reach the steady state to EC50 concentration/TEC50) of the DPPH curve were also evaluated for comparison with the Trolox equivalent (TE) values. A strong, significant and positive correlation was observed between the TE and AE values, whereas a weak and negative correlation was observed between TE and EC50, suggesting that the values of AE and TE are more useful for the determination of antiradical activity in fruits than the widely used EC50. The total phenolic content found in the fruits corresponded positively to their antioxidant activity. The high content of bioactive compounds (flavanols, anthocyanins or vitamin C) relative to the apple values found in araticum, cagaita, cajuzinho, jurubeba, lobeira, magaba and tucum corresponded to the high antioxidant activity of these fruits. Flavanols and anthocyanins may be the main bioactive components in these Cerrado fruits. The daily consumption of at least seven of the twelve Cerrado fruits studied, particularly, araticum, cagaita, lobeira and tucum, may confer protection against oxidative stress, and thus, they may prevent chronic diseases and premature aging. The findings of this study should stimulate demand, consumption and cultivation of Cerrado fruits and result in sustainable development of the region where this biome dominates.

Caracterização Química E Física De Frutos De Curriola, Gabiroba E Murici Provenientes Do Cerrado Brasileiro

“…Siqueira et al (2013) compararam a capacidade antioxidante, mensurada através de diferentes métodos (DPPH, FRAP e sistema betacaroteno/ácido linoleico), bem como o teor de compostos fenólicos, vitamina C, flavonoides e antocianinas entre diferentes frutos do Cerrado (araticum, baru, cagaita, cajuzinho, guariroba, ingá, jatobá, jenipapo, jurubeba, lobeira, mangaba e tucum) e maçã-vermelha (Malus domestica). Os frutos de araticum, cagaita, cajuzinho, mangaba, lobeira, jurubeba e tucum são expressivas fontes de compostos antioxidantes em comparação à maçã.…”

“…Essas frutas constituem uma fonte de compostos com propriedades funcionais benéficas à saúde, o que pode estimular seu uso pela indústria farmacêutica e de alimentos para o desenvolvimento de novos produtos, promovendo o desenvolvimento sustentável das regiões com as características do Cerrado (SIQUEIRA et al, 2013). Neste contexto, alguns estudos foram realizados acerca de seu efeito terapêutico (COSTA et al, 2013;GOUVEIA et al, 2013) e seu potencial na elaboração de produtos alimentícios (MORZELLE et al, 2009;MORZELLE et al, 2011;SALGADO et al, 2011;MORZELLE et al, 2012;ASSUMPÇÃO et al, 2013;SILVA et al, 2014).…”

Characterization of chemical and mineral composition of marolo (Annona crassiflora Mart) during physiological development

“…These fruits are a source of functional compounds with beneficial healthy properties, which might stimulate their use by the pharmaceutical and food industries for the development of new products, promoting the sustainability development of the regions with cerrado's characteristics (Siqueira et al, 2013). Nowdays, there are more than 58 species of natives fruits known and used by the population (Ávidos & Ferreira, 2005).…”

Mineral profile of cagaita (Eugenia dysenterica), mangaba (Harconia speciosa), and mama-cadela (Brosimum gaudochaudii Trecul) seed flours subjected to different drying temperatures and times

“…Potassium, calcium, and phosphorus contents stood out in cagaita, mama cadela, and mangaba flours, with values of 193.87 mg / 100g; 105.04 mg / 100g; and 234.142 mg / 100g, respectively. Minerals have several essential functions in the body, including regulating enzyme activitiy, maintenance of osmotic pressure, transport of nutrients, as constituents of body tissues such as bone and teeth, besides contributing to growth, immune function, and cognitive development (Siqueira et al, 2013;Anderson, 2005). As reported by Rigo et al, (2000), calcium (Ca) and phosphorus (P) are important to fetal and postnatal bone mineralization.…”
