ETHNOPHARMACOLOGICAL RELEVANCE Schinus molle L. has been used in folk medicine as antibacterial, antiviral, topical antiseptic, antifungal, antioxidant, anti-inflammatory, anti-tumoural as well as antispasmodic and analgesic; however, there are few studies of pharmacological and toxicological properties of Schinus molle essential oils. The aim of this study was to evaluate the antioxidant and a...

Lipid peroxidation (LPO), an oxidative chain reaction often occurring in the human body and food, is harmful to health. Due its convenience low cost, this guideline highlights benefits drawbacks of LPO models by spectrophotometer vitro vivo. The preparation process mechanism lipid substrates, oxidation triggers detection methods are discussed paper better screen antioxidants. substrates mostly ...

Extracts that were obtained with solvents of increasing polarity (hexane, dichloromethane, methanol, 80% and water) from the red macroalga Gracilaria domingensis evaluated by reducing power ferric reduction antioxidant (FRAP) Folin–Ciocalteu (FC) assays, lipid peroxidation inhibition β-carotene-linoleic acid assay, metal chelating ability based on iron-ferrozine system. The highest capacity was...

The essential oil (EO) obtained by hydrodistillation from Teucrium polium L. was analyzed by gas chromatography and gas chromatography mass spectrometry (GC/MS). Antioxidant activity was evaluated through DPPH assay and Beta-carotene/linoleic acid assay. Twenty one components were identified representing (90.4%) of the EO. Main constituents of the essential oil were found as Spathulenol (15.06%...

background: breast cancer is one of the main life-threatening diseases which a woman may face during her life. several lifestyle factors such as weight gain, obesity, fat intake and decreased level of physical activity are associated with breast cancer risk.   in vitro and vivo studies showed that, linoleic acid (la) is one of the main fatty acids composition of nigella sativa. the objective wa...

Six novel keto carotenoids have been isolated from the stick insect. The structure of the pre­ dominant red pigment has been assigned to 3,4,3',4'-tetradehydro-/?,/?-carotene-2,2'-dione on the basis of electronic, infrared, and mass spectra. Minor pigments are 3,4-didehydro-/?,^-carotene-2,2'dione, 2'-hydroxy-3,4-didehydro-/?,/?-caroten-2-one, and 2'-hydroxy-/?,/?-caroten-2-one. Two other com­ ...

conclusions p. spinosa ethanol extract can be used as a mouthwash for treatment of the oral infections. more clinical and toxicological studies are required for providing its efficacy. results p. spinosa ethanol extract with higher-level phenolic and flavonoid contents showed the highest antioxidant and antimicrobial effects, in comparison with the other extracts. bacillus sp. and streptococcus...

OBJECTIVE Polyunsaturated fatty acids such as linoleic acid are well known dietary lipids that may be atherogenic by activating vascular endothelial cells. In the liver, fatty acids can be metabolized by cytochrome P450 (CYP) enzymes, but little is known about the role of these enzymes in the vascular endothelium. CYP 2C9 is involved in linoleic acid epoxygenation, and the major product of this...

Skin diseases can get natural therapies from medicinal plant-based products. In this study, a topical cream was formulated ethanol extract of Acacia sieberiana, beeswax and Vitellaria paradoxa (shea) butter. GC-MS characterization with co-injection the revealed Stearic acid (31.43%), Palmitic (23.15%), Oleic (21.44%) Linoleic (16.20%) as major components. Seven phenolic conpounds were identifie...

Propolis is a resinous substance collected by bees from plants with a complex and variable chemical composition. Propolis and its fractions possess multiple biological activities. This study focused on a chemical and statistical comparison between four Tunisian Propolis Essential Oils (PEO) and its antioxidant activities. Volatile oils were extracted by hydrodistillation a...
