“…Tocotrienols are also the major tocols in other palm seed oils, such as those of Phoenix canariensis (Nehdi and others ), Whashigtonia filifera (Nehdi ), and Chamaerops humilis (Nehdi and others ). Elaeis guineensis oil fruit (palm oil) is also rich in tocotrienols (Kua and others ). All tocopherols and tocotrienols are potent antioxidants with lipoperoxyl radical‐scavenging activities.…”

This study showed that date seed had great nutritional value due to which it can be used for food applications especially as frying or cooking oil. In addition, date oil has also potential to be used in cosmetic and pharmaceutical practices as well. The extraction of oil from Phoenix dactylifera seed on large scale can create positive socioeconomic benefits especially for rural communities and could also assist to resolve the environmental issues generated by excess date production in large scale date-producing countries such as Saudi Arabia.

“…Today, it is well known that they possess hypocholesterolemic, anti‐cancer and neuroprotective properties . Also, due to their unsaturated chain their cell penetration is significantly improved which make them highly antioxidative . The predominant tocotrienols in the investigated seeds were β ‐tocotrienol and α ‐tocotrienol in S. officinalis and S. sclarea , respectively.…”

Composition of tocopherols, tocotrienols, carotenoids, fatty acids, as well as hydrophilic and lipophilic antioxidant activities, were determined in seeds of two Salvia species and oils obtained from them. Both seeds contained a large amount of oil (around 20%) rich in polyunsaturated fatty acids. While Salvia officinalis seed oil can be classified as oleic-linoleic oil, the predominant fatty acid in Salvia sclarea was α-linolenic acid (around 54%). Among tocols, the main isomers in both seeds and oils were γ-tocopherol, followed by α-tocopherol. Concerning carotenoids, their concentration was around 0.75 mg/100 g of seeds and 0.16 mg/100 g of oils, with a predominance of lutein. Oil and seeds of S. officinalis exhibited higher antioxidant potential compared to S. sclarea investigated samples which could be attributed to higher content of total vitamin E and carotenoids. This study provides results that enables use of two Salvia species as new alternative sources of vegetable oils.

During fruit processing, a large amount of solid residues such as seeds, remains underutilized. There is a need to find method for use of these by-products and to convert them into products with significant health, environmental and/or economic benefits. This study provides data about content of lipophilic antioxidants (carotenoids and tocols) and hydrophilic antioxidant potential of seeds of four autochthonous Balkan pear cultivars (Kajzerica, Kaluderka, Turšijara and Karamanka). The content of vitamin E ranged from 20.8 to 41.2 mg/100 g of seeds. In all of the investigated cultivars γ-tocopherol was dominant tocol, followed by α-tocopherol. Concerning carotenoids, their concentration ranged between 0.24 and 0.30 mg/100 g of seeds, with a predominance of lutein. The highest content of vitamin E and carotenoids was recorded in Kajzerica seeds. Antioxidant capacity of investigated samples was evaluated by hydrophilic Trolox Equivalent Antioxidant Capacity (TEAC) assay and it ranged from 2.3 mmol TE/100 g in Turšijara seeds to 14.6 mmol TE/100 g in Kaluderka seeds. Our results provide useful information for potential use of pear seeds.
