“…Moreover, compared to the values determined by Benmeddour et al [35] (1.6-30.3 µg/g DW) for ten cultivars of Algerian P. dactylifera fruits, the two P. canariensis fruits showed higher quercetin-3-O-glucoside contents. The caffeic acid content of the red variety was similar to the values found by Alahyane et al [14] (3.61-8.35 µg/g DW) for P. dactylifera fruits and higher than that determined by Benmeddour et al [35] (0.3 µg/g-1.2 µg/g DW) for ten Algerian P. dactylifera date cultivars. The rutin content of the yellow variety was higher than that determined by Bouhlali et al [30] (5.2-28.6 µg/g DW) and Benmeddour et al [35] (1.7-27.8 µg/g DW) for P. dactylifera fruits, while the rutin content of the red fruits was higher than that determined by Alahyane et al [14] (7.38-20.12 µg/g DW) for 17 Moroccan P. dactylifera date varieties and clones.…”

“…These values were also higher than those determined by Sheikh et al [33] (91.5-219.3 µg/g of dry extract) for three Saudi Arabian P. dactylifera date varieties. The gallic acid contents of the P. canariensis dates studied here, especially for the yellow variety, were higher than those determined by Alahyane et al [14] (43.7-314.11 µg/g DW), Bouhlali et al [30] (55.3-103.8 µg/g DW), and Al Harthi et al [34] (70-191.4 µg/g fresh matter) for different varieties of P. dactylifera fruits. For the yellow variety, the catechin content was in the same range of the values as determined by Alahyane et al [14] (18.67-72.75 µg/g DW) in P. dactylifera fruits, while quercetin-3-O-glucoside content in the yellow fruit was higher than that determined by Khallouki et al [31] (19.05 µg/g of fresh matter) for mature P. dactylifera Moroccan Medjool fruits.…”

“…The extraction of polyphenols was performed according to the method described by Alahyane et al [14], with slight modifications. Briefly, 1 g of the date powder was mixed with 30 mL of ethanol/water solution (80/20, v/v), and the extraction was performed at 25 • C for 2 h with a VDRL 711 orbital shaker (Asal S.r.l., Milan, Italy) under constant rotatory agitation at 60 rpm.…”

Phoenix canariensis Hort. Ex Chabaud, also known as the Canary Island palm or ornamental palm, is an endemic species of the Canary Islands and has been widely propagated globally. It has become one of the most important and appreciated ornamental plants, especially in the Mediterranean climate. The fruits are edible but used only for feed as they are bitter. Despite its diffusion, not much data on the composition of these fruits and their application as food are available. The aim of this study was to define the chemical characteristics, especially those of the polyphenolic constituents, of red and yellow varieties of Canary palm dates, and to evaluate their use alone or in different mixes in biscuit production. The yellow variety had higher quantities of fiber (36.88% DW (Dry Weight)) and polyphenolic compounds, while the red variety had a high content of sugars, mainly glucose (22.8% DW). Epicatechin is the most important polyphenol of dates (562 μg/g DW). The use of date palm powder on biscuit production resulted in an increase in hardness, polyphenol and fiber content, and antioxidant activity. Sensory analysis showed that the biscuits obtained with a 25/75 mix of red/yellow date powder had the most overall liking.

“…The A. amazonicum fruits are promising sources of nutrients and bioactive compounds, such as phenolic compounds, carotenoids, and ascorbic acid; however, to the best of our knowledge, the contents of the major nutrients and bioactive compounds were not yet reported in the literature. The frequent intake of bioactive compounds has been associated with the prevention of several chronicle degenerative diseases, such as cancer, cardiovascular, coronary heart, atherosclerosis, and neurological disease (Lavecchia et al, 2013), and these compounds have been reported to exhibit antioxidant, anti-inflammatory, antiallergic, antimicrobial, anticarcinogenic, antiviral and antimutagenic activities (Alahyane et al, 2019).…”

In this study, we reported for the first time about the physicochemical characterization, as well as the bioactive compounds in the peel and pulp of A. amazonicum fruits of two varieties harvested in Northern Brazil (Pará State) from two harvest periods (beginning and end). The peel and pulp of A. amazonicum fruits presented high contents of water (75-89%) and total carbohydrates (5-12%), whereas low total energetic value ranges (41-92 kcal/100 g, wet basis). Regardless the variety of A. amazonicum fruits, phenolic compounds were the major bioactive compounds, and the peels accumulated high contents at the beginning of the harvest period (4884-6556 mg GAE/100 g, dry basis, db), and at the end for the pulps (1394-2855 mg GAE/100 g, db). The multivariate exploratory techniques evidenced that high contents of bioactive compounds are available in the peel at the beginning of the harvest period, while at the end for the pulps. Caracterización y cuantificación fisicoquímicas de compuestos bioactivos de los frutos de Antrocaryon amazonicum cultivados en la Amazonia brasileña RESUMEN En el presente estudio informamos por primera vez sobre la caracterización fisicoquímica y los compuestos bioactivos presentes en la cáscara y la pulpa de los frutos de A. amazonicum de dos variedades cosechadas en el norte del Brasil (estado de Pará) durante dos periodos de cosecha (principio y fin). La cáscara y la pulpa de los frutos de A. amazonicum muestran altos contenidos de agua (75-89%) y de carbohidratos totales (5-12%), mientras que los rangos de valor energético total son bajos (41-92 kcal/100 g, base húmeda). Independientemente de la variedad de frutos de A. amazonicum de que se trate, siempre los compuestos fenólicos son los principales compuestos bioactivos; las cáscaras acumulan altos contenidos de los mismos al principio del periodo de cosecha (4884-6556 mg GAE/100 g, base seca (db)), en tanto que las pulpas lo hacen al final (1394-2855 mg GAE/100 g, db). El uso de técnicas de exploración multivariantes permitió poner de manifiesto que se dispone de un alto contenido de compuestos bioactivos en la cáscara al principio del periodo de cosecha, mientras que al final tal contenido está disponible para las pulpas.

Traditional oases in Northern Africa as multifunctional agroforestry systems: a systematic literature review of the provided Ecosystem Services and of the main vulnerabilities

Traditional oases represent unique forms of adaptation to extreme environmental conditions, developed through the centuries by local farmers to support their livelihood, combining different crops (date palms, fruit trees, vegetables and fodder) with livestock breeding. Despite their social, economic and cultural importance, these agroforestry systems are currently facing multiple socio-environmental threats. The aim of the paper is to investigate the variety of Ecosystem Services (ES) and the main threats related to traditional oases in Northern Africa through a systematic literature review. The search returned 257 relevant papers published from 2005 to March 2022, mostly focusing on Tunisian oases (37%), followed by Algerian (23%), Moroccan (19%), Egyptian (17%), and Libyan (4%). Provisioning Services, in particular Genetic diversity, agrobiodiversity and biodiversity, are the most cited ES (36% of the papers) followed by Cultural Services, mainly represented by Traditional knowledge systems, cultural heritage and sense of place (17%), while Regulating Services are less considered. Results highlighted that water related issues (desertification, drought, salinization or overexploitation) represent the main threat, followed by decrease of agrobiodiversity, primarily due to the spread of monocultures of commercial date varieties, and by social transformations (depopulation, traditional knowledge and cultural heritage loss). The literature review proved that traditional oases are still crucial for the livelihood of local communities since they still provide many ES. Local experiences related to sustainable development and tourism, or innovative solutions to valorize local products and byproducts, could be important for replication in other traditional oases to contribute to the wellbeing of local communities and to the preservation of these agroecosystems.
