“…A high positive correlation between phenolic compounds and FRAP assay has been reported by Alañón et al (2011). Some authors have suggested the fact that the FRAP assay was one of the major trials to confirm antioxidant activity (Gourine et al 2010;Farhoosh et al 2011;Hatamnia et al 2014Hatamnia et al , 2015.…”

“…However, this results is consistent with the finding of Hatamnia et al (2014), who showed the highest concentration of phenolic compounds observed in hull extract. The phenolic composition of extracts from genus Pistacia L. has been described before (Tomaino et al 2010;Hatamnia et al 2014Hatamnia et al , 2015, but this is the first report describing the phenolic profile of different parts of P. khinjuk fruit. Unfortunately, Downloaded by [University of Otago] at 03:30 13 July 2015 it is difficult to compare the phenolic profile results obtained by others authors because different species, different parts of plant or experimental conditions were used.…”

“…Antioxidants such as phenolic compounds including flavonoid, phenolic acids, tannins and phenolic diterpenes scavenge free radicals such as peroxide, hydroproxide or lipid peroxyl, and thus inhibit the oxidative mechanisms led to degenerative diseases and are of great benefits to our health (Chung et al 1998;Pietta 2000;Amarowicz et al 2004). Therefore, many studies were carried out on antioxidant and free radical scavenging activities of phenolic compounds in genus Pistacia L. (Hossein Goli et al 2005;Gourine et al 2010;Tomaino et al 2010;Farhoosh et al 2011;Hatamnia et al 2014Hatamnia et al , 2015.…”

The fruits of Pistacia khinjuk Stocks were collected from Ilam province, Iran. The aim of this study was to analyse antioxidant capacity and phenolic composition of different parts of P. khinjuk fruit. The antioxidant capacity of extracts was measured using different assays: ferric reducing ability of plasma, 2,2-diphenyl-1-picrylhydrazyl and nitric oxide radical scavenging. The phenolic composition of P. khinjuk fruit is reported for the first time. Amongst different parts of the fruit analysed in this study, hull extract contained the highest total phenolic and flavonoid contents. We observed a high correlation between different antioxidant activity and total phenolic and flavonoid contents. Therefore, antioxidant capacity can be related to total phenolic and flavonoid contents. A correlation analysis revealed that ascorbic acid, gallic acid, rutin, caffeic acid, ferulic acid and sinapic acid were the phenolic compounds mainly responsible for antioxidant power of the fruit extracts.

“…22,23 For the total flavonoids content, lower values have been reported for P. atlantica from the south-west of Morocco and Iran. 22,24 This could be explained by different factors as the genetic variability of the plant and the effect of the climat which is more tempered in the south of Morocco thanks to the oceanic influence. Table 3 shows the antioxidant activity evaluated by the three techniques.…”

Introduction:The extracts of the Pistacia species are known for their anti-inflammatory activity, including fruits and oil of P. atlantica. However, the inflammatory effect of the methanolic extract of P. atlantica leaves has not been studied. This work aimed at assessing the antiinflammatory and antioxidant activities of P. atlantica leaves extract in relation to phytochemical studies of flavonoids. Methods: The extract was obtained using sonication of leaves powder in 80 % methanol. The analysis of phenolic compounds was carried out using thin-layer chromatography (TLC). The antioxidant activity was evaluated using DPPH, ABTS and FRAP assays. The anti-inflammatory activity was determined by the reduction of carrageenaninduced hind paw edema in mice. Results: The TLC revealed 3 glycosylated flavonoids and gallic acid derivatives. The flavonoids identified corresponded to rutin, quercetrin and other heterosides of quercetin, kaempferol and myricetin. Total phenolics and flavonoids contents were comparable for the male and female trees. The antioxidant activity did not show a significative difference between the two sexes, except for that evaluated by the FRAP assay which was significantly greater for the male tree leaves extract. The leaves extract permitted significative reduction of the edema at h3 and 6 in a dose-dependent manner (100 and 250 mg/kg), while diclofenac used as control reduced the edema at h 1.5. This difference could be explained by the pharmacokinetic and pharmacodynamic properties of diclofenac and P. atlantica leaves compounds. Conclusion: P. atlantica has a strong anti-inflammatory activity and constitutes a potential source for the development of new treatments. Key words: Antioxidant activity, Flavonoids, Methanolic extract, Plantar edema, TLC. Oukacha ulcers.4 This has led to the search for alternative treatments. In this regard, secondary metabolites of various medicinal plants have been shown to be effective in the treatment of inflammation and pain.5 Among these plants, the species of Pistacia genus are of interest. Indeed, this genus includes 11 species that are widely distributed on the different continents of the terrestrial globe. They are found in temperate forests, tropical hardwoods and boreal conifers.6 P. atlantica is one of the most widespread wildlife species. It is the most characteristic plant of the arid and semi-arid zones of the northern part of Africa.7 In traditional medicine, P. atlantica is used for the treatment of pain and other conditions such as upper abdominal discomfort, dyspepsia and peptic ulcer.8 Several studies reported that the different parts of the plant as fruits, galls and oil, have biological effects including anti-inflammatory activities.9-12 However, as far as we know, no work has been devoted to the study of the anti-inflammatory effect of the methanolic extract of P. atlantica leaves (MEPaL). Thus, this study aimed at assessing the anti-inflammatory activity of DPPH scavenging activityThe antiradical power of substances was measured ...

Low-temperature storage is generally used to extend postharvest lifetime and to inhibit decay of cucumber fruit, but it also enhances the intensity of chilling injury. The capability of γ-aminobutyric acid to enhance antioxidant enzyme activities and reduce chilling injury was studied in cucumber ( L.) fruit stored at 1 °C for 5 weeks. The purpose of this study was to define if the GABA-induced modification in antioxidant system and phospholipase activity is linked to the reduced chilling injury in cold-stored cucumber fruit. Alleviation of chilling injury by GABA treatment was related to increased content of proline, endogenous GABA and enhanced activities of CAT and SOD, together with reduced activities of PLC, PLD and LOX. We suggest that PLC, LOX and PLD are associated with chilling injury initiation by involvement in a signaling pathway and membrane deterioration. Therefore the results obtained in this study suggest GABA's potential for postharvest applications for reducing chilling injury symptom in cucumber fruit.
