Increasing natural drug demand for pharmaceutical uses has encouraged scientifics all over the world to explore medicinal plants recognized as efficient remedies. In this context, extracted oil from pumpkin seeds (Cucurbita pepo L.) is an interesting target, it composed with prominent pharmacological properties possible wound healing treatments. The composition and content of certain bioactive constituents cold pressed obtained were analyzed studied their properties. Uniform wounds induced...
Abstract Quantitative and qualitative determinations of phenolic compounds were carried out on Chemlali olive leaves, a by‐product tree pruning. The evolution the amount major compound was monitored from July 2003 to March 2004. analysis performed by high‐performance liquid chromatography (HPLC), which revealed that oleuropein always compound. Its concentration reached 6.8 g per 100 fresh while monomeric phenols minor compounds. Beside oleuropein, six flavonoids (luteolin 7‐ O ‐glucoside,...
Fatty acid composition as an indicator of purity suggests that linolenic content could be used a parameter for the detection extra/virgin olive oil fraud with 5% soybean oil. The adulteration also detected by increase trans-fatty contents 3% oil, 2% corn and 4% sunflower use ΔECN42 proved to effective in Chemlali extra-virgin even at low levels: 1% sterol profile is almost decisive clarifying oils other cheaper ones: Δ7-stigmastenol campesterol. Linear discriminant analysis represent...
Abstract Background Rose-scented geranium ( Pelargonium graveolens L’Hér.), which is used in traditional Tunisian folk medicine for the treatment of hyperglycaemia, widely known as one medicinal herbs with highest antioxidant activity. The present paper conducted to test hypoglycemic and antioxidative activities leaf essential oil P. . Methods was administered daily orally rats at two doses 75 mg/kg 150 body weight (b.w.) 30 days. chemical composition oil, weight, serum glucose, hepatic...
Food waste and by-products have attracted attention in recent years due to the reduction of food resources negative impact on environment current production consumption systems. However, can be transformed into new products that useful for human because they represent a source nutritional technological (e.g., preservative, colorant, fibres) added-value compounds. Those compounds interest extracted using several advanced and/or emerging extraction techniques, which follow green chemistry...
Increasing interest in phenolic compounds olives is due to their antioxidant and health-enhancing properties. In this study the phenolics fruits of Tunisian olive cultivar Chemlali were extracted by methanol-water fractionated using Sephadex LH-20 column chromatography. The identification monomers flavonoids was based on separation high-performance liquid chromatography equipped with a diode array detector followed chromatography-mass spectrometry gas analysis. Oleuropein, secoiridoid...
For the first time identification and quantification of phenolic compounds Olea europaea L. cv. Chemlali olive were carried out to examine their profile during maturation. The composition was studied by using reverse-phase high-performance liquid chromatography all steps fruit development. Oleuropein is abundant compound in olive, its concentration increases An indirect relationship between oleuropein content hydroxytyrosol observed. Weak changes amounts other monomers flavonoids also total...
This study was designed to test the lipid-lowering and antioxidative activities of triacetylated hydroxytyrosol compared with its native compound, hydroxytyrosol, purified from olive tree leaves. Wistar rats fed a standard laboratory diet or cholesterol-rich for 16 weeks were used. The serum lipid levels, thiobarbituric acid-reactive substances (TBARS) level, as an indicator peroxidation, activity superoxide dismutase (SOD) well that catalase (CAT) examined. induced hypercholesterolemia...
Dhokar olive cultivar growing in the south of Tunisia is an unusual tree which characterized by sweet taste its fruit. We were particularly interested phenolic compounds this comparison to Chemlali cv. During different maturation stages fruits, composition, sugar content, antioxidant activity and enzymatic change examined. The composition was studied using reverse-phase high-performance liquid chromatography followed LC−MS GC−MS analysis. Oleuropein, major fruit biophenolic compound,...
