“…According to the literature, the fruit of feijoa may contain significant amounts of catechins, leucoanthocyanins, proanthocyanidins, naphthoquinones, syringic and trans-cinnamic acids in its flesh, whereas ferulic and o-coumaric acids and these occur most commonly in the peels (Romero Rodriguez et al, 1992;Ielpo et al, 2000;Tuncel and Yilmaz, 2015). Considering the results obtained in the present study, among the compounds identified in feijoa pulp, only quercetin is a flavonols which is commonly found in large amounts in onions, broccoli, apples and berries (Aherne and O'Brien, 2002;Arya et al, 2014).…”

The effect of processing on potential changes of antioxidant activity (DPPH and ABTS), total phenolic content (TPC) and total flavonoids (FLAV) of feijoa pulp during storage was investigated. In addition, possible modifications in the phenolic composition of the pulp. The pulp was subjected to refrigeration (control, 5 °C), pasteurization (85 °C/5 min) and irradiation (2.0 kGy). TPC, FLAV, DPPH and ABTS were measured during 28 days, whereas the identification and quantification of phenolic compounds were conducted after processing. The results were submitted to principal component analysis (SAS 9.4). Pasteurization preserved TPC, DPPH and ABTS for 21 days, while in the irradiated samples and control, the values were decreased and FLAV were maintained at high levels. The profile of phenolic compounds was different for each sample with six compounds being identified.

“…In the flesh of feijoa produced in Turkey, Tuncel & Yilmaz (2015) reported TAA values, quantified through the ABTS method, of 63.4-125.5 µmol L -1 Trolox per g dry weight (DW). Applying the DPPH method, they obtained EC 50 values of 2.56-1.36 mg DW per g DPPH (depending on the concentration of the hydroalcoholic solution and the extraction time).…”

-The objective of this work was to quantify the total phenolic content (TPC) and total antioxidant activity (TAA) of fruit from Brazilian genotypes of feijoa (Acca sellowiana). Skin and flesh tissues of the fruit were evaluated for the Alcântara, Helena, Mattos, and Nonante cultivars, and for the 2316 accession. TPC and TAA were both assessed in aqueous and hydroalcoholic extracts, and TAA was assayed by the DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS [2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)] methods. The TPC values, for aqueous extracts of the skin and flesh tissues, were 114.9 and 88.3 mg gallic acid equivalent (GAE) per 100 g fresh weight (FW), respectively. The corresponding values for TAA determined by the DPPH method, the skin and flesh tissues, given as EC 50 (substrate concentration which leads to 50% reduction of the DPPH), were 10.7 and 39.7 mg FW per g DPPH, respectively; and, by the ABTS method, the TAA values were 12.01 and 8.33 µmol L -1 Trolox per g FW, respectively. The greatest values for TPC and TAA were obtained for 'Mattos' and 'Nonante', in the skin, and for 'Nonante' and accession 2316, in the flesh. Feijoa fruit has important functional value, particularly in the skin, characterized by high TPC and TAA.Index terms: Acca sellowiana, Feijoa sellowiana, DPPH and ABTS methods, flesh and skin characterization, functional food. Compostos fenólicos e atividade antioxidante em frutos de genótipos brasileiros de goiabeira-serranaResumo -O objetivo deste trabalho foi avaliar compostos fenólicos totais (CFT) e atividade antioxidante total (AAT) em frutos de genótipos brasileiros de goiabeira-serrana (Acca sellowiana). As avaliações foram realizadas na casca e na polpa dos frutos, nas cultivares Alcântara, Helena, Mattos e Nonante, e no acesso 2316. CFT e AAT foram determinados em soluções extratoras aquosa e hidroalcoólica, e, para AAT, foram utilizados os métodos DPPH (2,2-difenil-1-picrilhidrazilo) e ABTS [2,2'-azino-bis (3-etilbenzotiazolin) 6-ácido sulfônico]. Os valores de CFT em extrato aquoso na casca e na polpa foram de 114,9 e de 88,3 mg em equivalente de ácido gálico (EAG) por 100 g de matéria fresca (MF), respectivamente. Para AAT, em extrato aquoso, na casca e na polpa, no método DPPH, os valores de EC 50 (concentração de substrato para reduzir em 50% a concentração inicial de DPPH) foram de 10,7 e 39,7 mg MF por g de DPPH, respectivamente; e, no método ABTS, foram de 12.01 e 8.33 µmol L -1 de Trolox por g de MF, respectivamente. Os maiores valores de CFT e AAT foram observados em 'Mattos' e 'Nonante', na casca, e em 'Nonante' e no acesso 2316 na polpa. Os frutos de goiabeira-serrana apresentam importante valor funcional, especialmente no tecido da casca, caracterizado pelos elevados conteúdos de CFT e alta AAT.Termos para indexação: Acca sellowiana, Feijoa sellowiana, métodos DPPH e ABTS, caracterização de polpa e casca, alimento funcional.

“…However, at present, there are still very limited studies focusing on the characterization of feijoa bioactive compounds, and the dominant anti-inflammatory compounds in feijoa remain unknown. Some research has stated that feijoa is rich in phenolic compounds [ 41 , 42 ], and the phenolic compounds could play an important role in the anti-inflammatory activity of feijoa. Aoyama, Sakagami and Hatano [ 43 ] identified seven phenolic compounds including flavone and ellagic acid in feijoa fruit, although their study did not involve anti-inflammatory tests, this information could be useful for future studies on feijoa bioactivities, including anti-inflammatory activity.…”

Screening of Cytotoxicity and Anti-Inflammatory Properties of Feijoa Extracts Using Genetically Modified Cell Models Targeting TLR2, TLR4 and NOD2 Pathways, and the Implication for Inflammatory Bowel Disease

et al. 2018

Feijoa has been increasingly studied in the recent decade, while investigations into its bioactivities including anti-inflammatory activity are lacking. In this article, the cytotoxicity and anti-inflammatory properties of feijoa extracts, from flesh, peel and whole fruit, from four cultivars namely APOLLO, UNIQUE, OPAL STAR and WIKI TU are presented. Three inflammatory pathways, Toll-like receptor 2 (TLR2), TLR4 and nucleotide-binding oligomerization domain-containing protein 2 (NOD2), were investigated using genetically modified cell models namely HEK-Blue™ hTLR2, HEK-Blue™ hTLR4, NOD2-WT and NOD2-G908R. Results show that feijoa peel extract induced higher cytotoxicity than flesh and whole fruit extracts, and the APOLLO cultivar was the most anti-inflammatory among the four tested cultivars. The anti-inflammatory activity of feijoa flesh was detected only through the TLR2 pathway, and the activity of feijoa peel and whole fruit was evident mainly through the TLR2 and NOD2 pathways. Most notably, feijoa anti-inflammatory activity was superior to ibuprofen particularly through the TLR2 pathway, with significantly lower secreted embryonic alkaline phosphatase IC50 concentrations (7.88, 12.81, 30.84 and 442.90 μg/mL for APOLLO flesh, peel, whole fruit extract and ibuprofen respectively). These findings indicate that feijoa has great potential to be used in the treatment and prevention of inflammation-related diseases including inflammatory bowel disease.
