Physicochemical characteristics, nutritional composition, and phytochemical profiles of nine Algerian date palm fruit (Phoenix dactyliferaL.) varieties

Abstract

Nine varieties of Algerian date palm fruits (Phoenix dactylifera L.) including Lahmira, Timjouhert, Adham Talmine, Deglet Talmine, Adam Boullah, Tinasser, Deglet, Deglet Nour, and Takerbouch were distinguished via Proton Nuclear Magnetic Resonance (1H‐NMR) metabolomics approach. The quality was evaluated based on the metabolite composition, proximate analysis, physicochemical characteristics, and biological activities which include nitric oxide (NO) inhibition via the cell‐based approach and NO scavenging abilities. A total of 49 metabolites were tentatively characterized including amino acids, organic acids, and phenolic compounds. The Principal Component Analysis and Hierarchical Clustering Analysis revealed a consistent grouping of Deglet, Takerbouch, and Deglet Noor from the rest of six varieties. Among the metabolites that contributed toward the observed segregation were serine, glycine, glucose, fructose, and sucrose. With regard to metabolite composition, NO scavenging activities, total soluble solids, and proximate analysis, Deglet dates displayed a better quality as compared to the other Algerian dates. Practical applications The present study has the significance in assessing the variation among different varieties of Algerian dates via the 1H‐NMR metabolomics approach. The information gained might be beneficial for consumers and suppliers regarding the quality of the selected varieties of date palm fruits. Generally, the obtained data intend to contribute to the knowledge on the quality differences among varieties of dates. Thus, the selection of premium date variety with good nutritional and pharmacological values can be chosen in the development of functional food.

Physical Fruit Traits, Nutritional Composition, and Seed Oil Fatty Acids Profiling in the Main Date Palm (Phoenix dactylifera L.) Varieties Grown in Morocco

“…For fruit flesh, CC exceeded 76% of the total composition, with the best record being presented by "Bouskri" (90.18%). ese results were consistent with published literature [15,27]. CC found in flesh date fruit consist mainly of reducing sugars and dietary fibers are a minor fraction.…”

“…For the studied varieties, PC ranged from 1.60 ± 0.11% obtained in "Boufgous" to 3.53 ± 0.20% obtained in "Jihel" for flesh part and from 3.20 ± 0.21% in "Amouch" to 5.00 ± 0.10% in "Ismmarti" for seeds part. Our findings were in line with other works carried out in Morocco and abroad involving several varieties [27,31,32]. Date fruits showed higher PC than other fruits such as apples (0.3%), oranges (0.7%), bananas (1.0%), and grapes (1.0%) [33].…”

“…Al-Harrasi et al [5] successfully separated 22 date palm dates grown in Oman based on nutritional and chemical profiling combined with PCA. Similar results were highlighted in the work of Abdul-Hamid et al [27] for five varieties from Saudi Arabia, Tunisia, and Iran.…”

Biological Activities of Selected Plants and Detection of Bioactive Compounds from Ardisia elliptica Using UHPLC-Q-Exactive Orbitrap Mass Spectrometry

“…Apart from phenolic compounds, the presence of plant steroids, triterpenoids, and other nitrogenous compounds was also responsible for anti-diabetic effects [7]. The complexity of plant metabolites anticipated the simultaneous interactions of various phytoconstituents either synergistically or antagonistically on the bioactivities [21]. Therefore, the findings of this study further strengthen previous claims regarding the anti-diabetic potential of these plants.…”

“…Sukkari dates are rich in these compounds compared to Deglet Nour variety. However, Deglet Nour are higher in sucrose content (Abdul‐Hamid et al, 2018). Additionally, fructose and galacturonic acid in Deglet Nour were found to be 2.51% and 2.23%, respectively.…”
