Evaluation of the antioxidant, antiproliferative and antimutagenic potential of araçá-boi fruit (Eugenia stipitata Mc Vaugh — Myrtaceae) of the Brazilian Amazon Forest

Elaboration and Characterization of Apple Nectars Supplemented with Araçá-boi (Eugenia stipitata Mac Vaugh—Myrtaceae)

“…The antioxidant capacity by DPPH method was 30.60 µmol (7.66 mg) TE/g of fruit dw (Table 5), equivalent to 3.69 µmol (0.92 mg) TE/g fw, while Garzón et al (2012) [19] found 0.5 mg TE/g fw. As for TEAC method, the antioxidant capacity obtained here (48.73 µmol (12.19 mg) TE/g of fruit dw (Table 5), equivalent to 5.88 µmol (1.47 mg) TE/g fw) was also higher than the values reported by Garzón et al (2012) [9] (0.65 mg TE/g fw), Canuto et al (2010) [34] (0.75 mg TE/g fw) and Lizcano et al (2010) [36] (1.4 mg TE/g fw). As for the ORAC method, we obtained an antioxidant capacity of 135.3 µmol TE/g of fruit dw (Table 5), equivalent to 16.33 µmol TE/g fw, while Lizcano et al (2010) [36] and Neri-Numa et al…”

“…In terms of phenolic compounds and antioxidant capacity of FD, some differences were observed between this and other studies. The total phenolic compounds found here, 82.32 mg GAE/100 g of fruit dw (Table 5), equivalent to 9.94 mg GAE/100 g fw, was lower than the values reported by Garzón et al (2012) [19] (34.1 mg GAE/100 g fw), Lizcano, Bakkali, Begoña Ruiz-Larrea, & Ignacio Ruiz-Sanz (2010) [36] (157.00 mg GAE/100 g fw) and Neri-Numa et al (2013) [9] (184.08 mg GAE/100 g dw), while the level of flavonoids found here (90.78 mg CE/100 g of fruit dw, equivalent to 10.96 mg CE/100 g fw), was higher than that determined by Lizcano et al (2010) [36] (5 mg CE/100 g fw). The antioxidant capacity found in the present study was also higher than those found in previous results.…”

“…(2013) [9] found an antioxidant capacity of 12.1 µmol TE/g fw and 3.72 µmol TE per g of freeze-dried ethanolic extract, respectively. It is known that the physical and chemical constitution of a given fruit is determined by an integrated effect of many factors, such as variety, weather conditions, soil, altitude, fertilization, irrigation, pests, pruning, among others [37].…”

“…In the same way, the extract of E. stipitata fruit showed good antioxidant capacity and a total phenolic amount rated as medium. Moreover, antimutagenic and antigenotoxic activities were observed at 300 mg of extract/kg bw [9].…”

“…In this context, Brazil offers a wide variety of native fruits with nutritional qualities and health claims that are still little known by consumers. Thus, considering their exotic character and potential health benefits, the introduction of these fruits on food chains could represent an important economic activity not only for local but also to the growing international markets [7][8][9][10].…”
