BACKGROUND
Pinus halepensis (Aleppo pine) is a widespread tree that can be found in both natural and urban environments. A discrimination study based on the antioxidant compounds, antioxidant capacity and fatty acid (FA) profile of P. halepensis cones (PHC) and seeds (PHS) was performed.
RESULTS
The
Pigment levels and antioxidative stress-related metabolites were determined over a period of two years in Pinus halepensis to characterize the response of some plant protective processes to both environmental stresses and 03 exposure. Two-year-old-Aleppo pine seedlings were grown in open-top
The impact of growth stages during vegetative cycle (B0 - B5 ) on chemical composition and antioxidant activities of Pinus halepensis Mill. needles essential oils was investigated for the first time. GC and GC/MS analyses pointed to a quantitative variability of components; terpene hydrocarbons
Numerous studies have focused on trans fatty acids (TFA) technologically produced by partial hydrogenation of oils. However, TFA can also be present in fresh oils. For this reason, cis fatty acid (CFA), TFA and conjugated linoleic acid (CLA) of fresh and heated Aleppo pine seed oil (APSO) at frying
BACKGROUND
The aim of the present research was to investigate the potential use of a natural compound rich in antioxidant agents, derived from Pinus halepensis (P. halepensis), to prevent PDT induced photosensitivity. The present research progressed in two levels. The first one evolved the
BACKGROUND
Use of antioxidants is a means of reducing rancidity of fats and oils in food stuffs. The commercial synthetic antioxidants in food industry have been suspected to cause negative health effects. Therefore as alternatives, there is a strong need in finding new effective and safe
Background/aim: Cigarette smoke (CS) is a major environmental health threat. The oxidative stress induced by CS on keratinocytes and the possible protective effect of nicotine, its receptor inhibitors, and Pinus halepensis bark extract in
Non-invasive biophysical methods were used to study the effect of antioxidant gels, which were prepared from Pinus halepensis bark extracts, vitamin C and water, on the skin of diabetic hairless mice irradiated with UV radiation of 1 and 2 minimal erythemal doses (MEDs). The calculated
Aromatic and medicinal plants are sources of natural antioxidants thanks to their secondary metabolites. Administration of Pinus halepensis L. (Pinaceae family) in previous studies was found to alleviate deleterious effects of aspirin-induced damage on liver and kidney. The present study, carried
In this study, we tested 10 essential oils (EOs) extracted from 10 plants issued from Sned region (Tunisia) to evaluate both their leishmanicidal effects against Leishmania major and L. infantum, and their cytotoxicity against murine macrophage cell line RAW 264.7 (ATCC, TIB-71). The antioxidant
BACKGROUND
Forest species ranges are confined by environmental limitations such as cold stress. The natural range shifts of pine forests due to climate change and proactive-assisted population migration may each be constrained by the ability of pine species to tolerate low temperatures, especially
The most prevalent neurodegenerative disease is Alzheimer's dementia. It is determined by the deposits of amyloid-beta peptide which leads to memory impairment, oxidative stress, and neurodegeneration. Aromatherapy by using essential oils could represent a natural treatment option for Alzheimer's
This study was designed to evaluate, for the first time, the effect of the precipitation solvent (Acetone, Ethanol, and Propanol) on the antioxidant, anti-inflammatory and anticoagulant activities of the polysaccharides extract from Aleppo pine seeds. The antioxidant activity was evaluated with
Seeds of Pinus halepensis are used for preparing zgougou, a spontaneously fermented matrix giving juice and seeds debris, consumed in many Arabian countries, including Tunisia. In the same way as all the food processes based on spontaneous fermentation, zgougou hides health risks due to
