Total phenolic content and free radical scavenging activities of methanolic extract powders of tropical fruit residues

Yellow passion fruit seed oil (Passiflora edulis f. flavicarpa): physical and chemical characteristics

“…Regarding phenolic compounds, the concentration found in the passion fruit seed oil (1,314.13 mg EAG /kg) was comparable to that found in other vegetable oils, such as oils extracted from blueberry, raspberry and blackberry seeds (Parry et al 2005). Oliveira et al (2009) determined the total phenolic concentration in methanol extracts from the passion fruit waste (pulp, skin and seeds) and found 41.2 mg EAG/g dry extract. According to Haiyan et al (2007), only a small portion of the seed total phenolics is transferred to the oil during the extraction process.…”

Ethanolic extract of Passiflora edulis Sims leaves inhibits protein glycation and restores the oxidative burst in diabetic rat macrophages after Candida albicans exposure

“…The phenolic content of P. edulis (4.67 ± 0.115 g GAE/100 g extract) observed in the ethanolic extract was similar to the concentrations reported by Oliveira et al (2009), when passion fruit methanol extract waste was examined. Furthermore, the P. edulis ethanolic extract phenolic content was higher than the concentrations that were observed in different studies with other herbal extracts that have potential anti-inflammatory and hypoglycaemic properties (Caia et al, 2004;Souza et al, 2008).…”

Effects of ultrasound and chemical treatments on white mushroom (Agaricus bisporus) prior to modified atmosphere packaging in extending shelf-life

“…Polyphenolic compounds are very important fruit constituents because of their antioxidant activity in chelating redox-active metal ions, inactivating lipid free radical chains and preventing hydroperoxide conversion into reactive oxyradicals (Oliveir et al 2009). Total phenol contents of mushrooms from different treatments at 4°C during 12 days of storage are presented in Table 2.…”
