Effect of seed's geographical origin on cactus oil physico-chemical characteristics, oxidative stability, and antioxidant activity.

The aim of this study was the valorisation of cactus (or prickly pear, ) seeds growing in six different regions of Morocco. Moisture, proteins, lipids profile, total polyphenols content, oxidative stability, and antioxidant activity were investigated. The Folin-Ciocalteu test highlighted the abundant presence of phenolic compounds (165 to 225 mg EAG/100 g of extract) and a significant antioxidant capacity against DPPH free radicals.

Proximate composition, lipid and elemental profiling of eight varieties of avocado (Persea americana).

Eight Moroccan avocado varieties were analyzed for their nutritional composition and physicochemical properties. The nutritional contents of the sample were determined through the evaluation of the moisture, oil, ash, protein, and carbohydrate contents, and energy value calculation. Additionally, macroelements (Ca, Mg, and Na) and microelements (Fe, Zn, Cu, and Mn) were determined in the mineral profile.

Apiaceae Family an Important Source of Petroselinic Fatty Acid: Abundance, Biosynthesis, Chemistry, and Biological Proprieties.

Petroselinic fatty acid (PeFA) is considered a rare fatty acid and one of the most important fatty acids in the Apiaceae family. Its content varies depending on plant species, geographical origin, extraction method, ripeness, etc. Indeed, reported levels of petroselinic fatty acid range from 10.

Polyacetylenic caffeoyl amides from Ammodaucus leucotrichus.

Six undescribed polyacetylenic caffeoyl amides, five known flavones and three known lignans were obtained from the fruits of the North African traditional medicinal plant Ammodaucus leucotrichus Coss. & Durieu (Apiaceae). Isolation was achieved by a combination of chromatographic methods, and structures were established by extensive 1D and 2D NMR spectroscopy, mass spectrometry, electronic circular dichroism, and by GC-MS analysis of sugar derivatives.

Proximate Composition, Physicochemical, and Lipids Profiling and Elemental Profiling of Rapeseed ( L.) and Sunflower ( L.) Grown in Morocco.

We investigate and compare the nutritional and physicochemical properties of rapeseed and sunflower grown in Morocco. In order to examine a complete physicochemical characterization, various parameters such as mineral profile, fatty acid composition, sterols contents, total flavonoids content (TFC), total polyphenols content (TPC), and quality oil parameters were evaluated. The results showed a relatively small difference in the physicochemical composition of the seeds, as sunflower seeds recorded higher amounts of protein and oil content (22.

Profile of Volatile Aroma-Active Compounds of Cactus Seed Oil () from Different Locations in Morocco and Their Fate during Seed Roasting.

Volatile compounds from oils extracted from cactus seeds () of five regions of Morocco were analyzed by dynamic headspace-GC/MS. Aroma active compounds were characterized by olfactometry. A total of 18 compounds was detected with hexanal, 2-methyl propanal, acetaldehyde, acetic acid, acetoin and 2,3-butanedione as most abundant.

Chemical Composition and Antioxidant Activity of Lawsonia inermis Seed Extracts from Morocco.

The aim of the present study was to investigate the composition of Lawsonia inermis (henna) seed oil from Morocco and to evaluate some of its activities in order to use it in cosmetics. Phytosterols are valuable henna-oil constituents, but henna oil does not present any interesting antioxidant activity.
