Phoenix dactylifera is a useful traditional medicinal plant, mainly the fruit is used, which is the edible part of the plant (Ajwa date). It is now considered to be a valuable source of natural medicinal products against various diseases. Phytochemical investigations have shown that the fruit contains anthocyanins, phenolics, sterols, carotenoids, and flavonoids. The fruits are a rich source of carbohydrates, vitamins, and proteins. P. dactylifera is considered as a complete diet because it also contains different fatty acids, amino acids, proteins, and steroidal substances. This review highlights the phytochemical composition, nutritional significance, and potential health benefits of P. dactylifera and discusses its potential as a functional food for disease prevention, management, and treatment.

The fatty acid composition of date seed oil from two different date palm ( Phoenix dactylifera L.) cultivars, locally known as Degla-Baïdha and Tafezouine, were investigated. GC analysis revealed the presence of five dominant fatty acids: oleic C18:1 (46.51; 39.15%), lauric C12:0 (22.1; 28.5%), myristic C14:0 (10.7; 11.4%), palmitic C16:0 (9.6; 8.7%) and linoleic C18:2 (6.9; 6.1%). The oils was characterised by a low content of tocopherols (0.53; 1.41 μg/g). The antioxidant activity of the oils was investigated using the DPPH•(1,1-di-phenyl-2-picryl-hydrazyl) scavenging assay. The oils had a weak bleaching effect on DPPH• free radicals. This study showed that the qualities of the tested oils are highly comparable with those of some commercial seed oils of other plants. Furthermore, a statistical analysis using the hierarchy ascendant classification method was conducted in order to highlight the similarities and/or the differences regarding the contents of the main fatty acids found in some common plants and in the five most famous cultivars of Phoenix dactylifera of south eastern Algeria (Tafezouine, Degla-Baïdha, Deglet-Nour, Ghars, Tamdjouhert).

Date palm (Phoenix dactylifera) is one of the most widespread fruit crop species and can tolerate drastic environmental conditions that may not be suitable for other fruit species. Excess UV-B stress is one of the greatest concerns for date palm trees and can cause genotoxic effects. Date palm responds to UV-B irradiation through increased DEG expression levels and elaborates upon regulatory metabolic mechanisms that assist the plants in adjusting to this exertion. Sixty-day-old Khalas date palm seedlings (first true-leaf stage) were treated with UV-B (wavelength, 253.7 nm; intensity, 75 μW cm−2 for 72 h (16 h of UV light and 8 h of darkness). Transcriptome analysis revealed 10,249 and 12,426 genes whose expressions were upregulated and downregulated, respectively, compared to the genes in the control. Furthermore, the differentially expressed genes included transcription factor-encoding genes and chloroplast- and photosystem-related genes. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to detect metabolite variations. Fifty metabolites, including amino acids and flavonoids, showed changes in levels after UV-B excess. Amino acid metabolism was changed by UV-B irradiation, and some amino acids interacted with precursors of different pathways that were used to synthesize secondary metabolites, i.e., flavonoids and phenylpropanoids. The metabolite content response to UV-B irradiation according to hierarchical clustering analysis showed changes in amino acids and flavonoids compared with those of the control. Amino acids might increase the function of scavengers of reactive oxygen species by synthesizing flavonoids that increase in response to UV-B treatment. This study enriches the annotated date palm unigene sequences and enhances the understanding of the mechanisms underlying UV-B stress through genetic manipulation. Moreover, this study provides a sequence resource for genetic, genomic and metabolic studies of date palm.

Fatty Acid Compositions

The proximate, sugar, minerals and fatty acids composition of date palm fruit were determined. The moisture content is 5.24 ± 0.05%, ether extract value is 1.54 ± 0.01%, crude fibre content is 4.34+ 0.03%, crude protein content is 4.94+0.04% while the value of carbohydrate is 80.87 ± 0.05%. The fractions of sugar contained maltose (33.7mg%), fructose (22.8mg%) and glucose (22.3mg%). The most abundant minerals in the sample is potassium with the value of 710.0 mg% sample. The most concentrated fatty acids were oleic acid (44.51g/100g) > palmitic acid (23.05g/100g) > linoleic acid (11.66g/100g). All these quality food properties make it good source of unsaturated fatty acids and sweetening agent in food processing industry. Key words: Carbohydrates; Fatty acids; Minerals; Fruit flour.
