“…These results showed superior potential of QIG in terms of K content indicating that QIG could be evaluated as a rich K source. Health beneficial effects of K were reported by previous studies ( Aouinti et al, 2014 ) . K‐rich diet may help to remove excess sodium and by this way reduce the blood pressure ( Aburto et al., 2013 ) , protect the body against stroke, and prevent the formation of osteoporosis and kidney stones ( Gallen et al., 1998; New et al., 2000 ) .…”

This study was aimed to investigate chemical composition, biological activity, and food protecting ability of Quercus infectoria gall (QIG).The total content of phenolics, flavonoids, and hydrolyzable tannins was evaluated. Ion and fatty acid compositions of QIG were identified by ion chromatography and gas chromatography flow ionization detector (GC‐FID), respectively. Ellagic acid (28,156.85 mg/kg) and catechin (716.21 mg/kg) were predominant. The antioxidant activity of QIG was determined as 2.29, 1.65, 1.52, and 1.98 mmol Trolox equivalent antioxidant capacity (TEAC)/g sample for DPPH, ABTS, FRAP, and CUPRAC analyses, respectively. QIG extract exhibited dose‐dependent inhibition on α‐glucosidase enzyme with an IC50 value of 0.002 mg/ml. QIG displayed antimicrobial activity against selected reference and isolated mixed strains, most notably on Escherichia coli. The addition of QIG extract as a natural preservative to pasteurized cow’s milk resulted in lower total bacterial count (TBC), total yeast‐mold count (TYMC), and higher pH compared to control milk. Practical applications Quercus infectoria gall does not have a common use in the food and pharmaceutical industry. Exploration of the the biological value of Q. infectoria gall or its extracts could pave the way for the development of added value natural food preservatives and functional compounds. The chemical composition of Q. infectoria gall should be characterized and its biological functionality should be demonstrated beforehand. The results indicated that this plant could be considered as natural antidiabetic, antioxidant, and protective agents instead of synthetic materials and ingredients for food, cosmetic, and pharmaceutical applications.

“…Actually, in a previous study about Algerian P. lentiscus, Benyoussef et al (2005) found 4-terpineol, ␣-terpineol, and germacrene D among the principal chemicals. However, such a differences in the chemical composition of P. lentiscus essential oil may be due to the different geographical area of growth and period of harvesting of the plant material (Zrira et al, 2003;Aouinti et al, 2013).…”

Rhyzopertha dominica, Sitophilus zeamais, and Tribolium confusum are three of the major food-stuff pests who cause important economic losses of shelved products with special reference to pasta. Due to its long shelf life, pasta is highly exposed to insects that can penetrate into the packaging with consequences economically severe. Eco-friendly strategies to prevent such insect attacks to the final packaged product are therefore highly foreseen by pasta companies. Due to their repellent properties, essential oils, extracted from aromatic plants, could represent a valid, eco-friendly alternative to chemical repellents. In this study, we evaluated the repellent activity of Pistacia lentiscus essential oil (PEO) and its main chemical components by two different bioassay with and without the presence of pasta. Results showed that the whole PEO exerts a broad-range aspecific repellency among the target pests with RD50 values ranging from 0.010 to 0.037 μL cm−2. On the contrary, the repellence of PEO components resulted to vary depending on the compound and on the pest species. Among the PEO chemical components, relative median potency analyses indicated that β-caryophyllene was able to exert the highest repellency rates against S. zeamais (RD50 0.046 μM cm−2). The comparison between the two bioassays, with and without pasta, indicated that the two methodologies gave consistent results. Overall, our research firstly showed that, because of their effectiveness as repellents, PEO and its major constituents could represent valid and safe tools against pasta pest

This study was aimed to phytochemically characterize and assess the antioxidant activities of 70% methanol extract and subsequent fractions of Cassia absus (L.) seeds, Gymnema sylvestre (L.) whole plant, Nigella sativa (L.) seeds, and Piper nigrum (L.) seeds. Powdered plant materials were extracted with 70% methanol and further fractionated with ethyl-acetate, n-butanol and the residual aqueous fraction. Phytochemical analysis was performed to detect different phytocompounds. Mineral compositions were quantified, and total phenolic and flavonoid contents were determined. The antioxidant potential of methanol extracts and fractions was assessed in vitro through estimating DPPH radical and superoxide anion scavenging activities and reducing power assay. Extraction yields ranging highest of N. sativa methanol extract (30.42�1.49%) and lowest of P. nigrum ethyl-acetate fraction (4.58�0.61%) were obtained. Results revealed that methanol extracts and fractions of selected plants contain phytocompounds such as alkaloids, flavonoids, phenols, glycosides, tannins, terpenoids, saponins, carbohydrates, fats and fixed oils. The mineral analysis showed considerable quantities of calcium (C. absus methanol extract: 372.454�3.633 mg/100g), magnesium (G. sylvestre methanol extract: 131.045�1.346 mg/100g), and zinc (N. sativa methanol extract: 36.019�0.284 mg/100 g) in all fractions while minor quantities of manganese, copper and cobalt were also found. Methanol extracts showed considerably higher total phenolic (N. sativa methanol extract: 179.71�2.14 mg GAE/g) and flavonoid (N. sativa methanol extract: 189.18�3.17 mg CE/g) contents compared to other fractions, and subsequently exhibited pronounced scavenging activities on DPPH* (N. sativa methanol extract: 23.8 �g/mL) and superoxide radicals (N. sativa methanol extract: 24.9 �g/mL) and had potent reductive abilities (N. sativa methanol extract: 1.123�0.038 O.D.). Conclusively, C. absus, G. sylvestre, N. sativa and P. nigrum possess significant nutritive properties and could be used as natural antioxidant sources to prevent oxidative stress-associated diseases.
