“…Similar observations were made by Rezig et al [39] on Cucurbita maxima Pumpkin seed oil where the -tocopherol contents were 599.33 mg/kg and 239.60 mg/kg respectively for cold extraction with the Komet press and hexane. Linseed oil contains 1 mg / 100 g of -tocopherol and 50 mg / 100 g of -tocopherol [40]. The results found showed that the extraction technique affects significantly the tocopherol content.…”

Tetracarpidum conophorum nut is an oil seed found abundantly in the equatorial forest of Central Africa. The present study was conducted to evaluate the yield and the physicochemical composition oils from T. conophorum kernels extracted by cold and hot pressing. The experiments were carried out with mechanical screw press (type – Komet D85-1G) with a nozzle diameter of 8 mm. The extraction method had an influence on oil yield, with a greater yield for hot pressing at 90 °C (68.86 ± 2.00%) compared to cold pressing at 30°C (64.65±3.82%). The refractive index and the density of oils were not significantly different with respect to the extraction methods. The iodine value varies from 146 for hexane extraction to 170 for cold extraction. For both oils, the acid and peroxide values were in line with Codex standards. The oil extracted with hot press method had higher carotenoid content (32.03 ± 1.86 µg/g). a-tocopherol was greater in the oil obtained through the cold process (16.2 ± 0.20 mg/100 g). The seed oils contained substantial amounts of polyunsaturated fatty acids, including precisely linolenic acid (68% of total fatty acids) and linoleic acid (11% of total fatty acids). Based on its characteristics, oils obtained through cold press extraction was of better quality with respect to preservation of bioactive components. T. conophorum oil may have interesting abilities in nutrition, pharmacology and management of metabolic diseases.

“…There is not a significant difference of this fatty acid whatever the mode of extraction. T. conophorum oil is richer in -linolenic acid than linseed (54%), walnut (9-15%) and rapeseed (8-10%) oil [40].…”

“…However, the values found are lower compared to the values reported in the literature. For example, Da Porto et al (2015) reported values between 3 and 7% for clinolenic acid in northern Italy, Morin (2015) reported values of 2% to 4% in France, and Abdollahi et al…”

“…This oil has also an interesting level of c-linolenic acid, which several studies have shown its beneficial effects on human health (Leizer et al, 2000;Veselinovic et al, 2017). Cannabis seed oil has thus been officially approved as an edible oil in France since 2002 (Morin, 2015). Likewise, the antioxidant, anti-inflammatory and anticancer properties of the bioactive molecules of Cannabis seed oil have been demonstrated by several authors (Yu et al, 2005;Frassinetti et al, 2018).…”

This study aims to determine the chemical composition of hemp (Cannabis sativa L.) seeds of two varieties cultivated in four different regions of northern Morocco. The content of protein, insoluble fibre, ash, total phenols and flavonoids was found to be 19. 25%-24.18%, 26.40%-37.40%, 3.72%-5.39%, 134.57-199.90 mg 100g À1 and 39.40-69.54 mg 100g À1 respectively. Oil contents ranged from 26.42 to 35.19 g 100 g À1 of seeds in the four collection sites with variable oxidative stability at 100°C from 9.73 to 15.42 h. Total tocopherol content was between 376.46 and 796.06 mg kg À1 of oil, with a dominance of ctocopherol. Fatty acids consisted mainly of unsaturated fatty acids (87.30-88.96%) with a predominance of linoleic acid (48.26%-55.39%). Triacylglycerols (TAGs) composition analysis revealed the presence of 18 TAGs with an equivalent carbon number of 38-48. The composition of TAGs was predominated by LLL (14.34%-22.62%), OLL (12.77%-18.78%) and LLLn (12.32%-18.59%). Furthermore, the majority of the evaluated parameters were strongly influenced by the varietal factor, growing area and their interaction. The knowledge of this composition variability in seeds of non-industrial Cannabis sativa varieties cultivated in northern Morocco could be useful in new Cannabis variety breeding programmes potentially valuable as non-conventional oil in cosmetic and agro-industry.
