Abstract Our aim in this study is to build a model for the expansion of date palms (Phoenix spp., Arecaceae) that can be linked to domestication processes. Palaeontological and archaeobotanical evidence concerning date palm is extremely diversified around the Mediterranean Basin and in West Asia, mainly consisting of date fruit remains, but also including leaf fragments and other plant remains. This biological evidence is further compared with cultural evidence (coins, pottery, ancient texts) and the present distribution of Phoenix spp. in the area. Bayesian methods working with likelihood and conditional probabilities are successfully applied to generate a model for displaying in maps the ancient distribution of palm groves in terms of probabilities. The model suggests that the domestication of Phoenix dactylifera occurred mainly east of 30°E, probably in the Jordan Valley area, starting before 7 kya and, in a westward shift, that this was gradually superposed onto pre-existing local western populations of the same genus, especially in the Nile valley. It appears that this mainly affected the P. dactylifera western cluster (P. excelsior, P. atlantica, P. iberica). However, other taxa persisted as independent species (P. theophrasti, P. canariensis).

‘Piyarom’ dates are one of the most important commercial date cultivars grown in Iran but fruit quality and postharvest losses can be a problem. Thinning and the use of bunch covers were examined to improve the date fruit quality. Three different levels of fruit thinning were applied (without thinning, removal of one third of total strands from terminal tips during pollination and removal of one third of terminal tips of central strands in early kimri). In addition, the effects of bunch covers were assessed with the use of polyethylene bunch covers that were applied in the early stages of Khalal. The results showed that bunch covering reduced the lightness of the fruit but increased bunch weight, fruit length, total antioxidant activity and total phenolic compounds compared to the control. Thinning during pollination increased the weight of the fruit compared to the control. The thinning during Kimri stage increased the percentage of Tamar and ascorbic acid content. These results show that the use of covers play a positive role in increasing quality and bunch weight and thinning at both pollination and Kimri ripening stage is recommended to produce high quality ‘Piyarom’ dates.

Abstract Background: The rate of cesarean section is increasing in all over the world with different drafts in various countries. This growth increases unpleasant outcomes of delivery. Recent studies explained the benefits of date palm fruit on labor process improvement. Date fruit can be considered as a factor for increasing vaginal delivery and also reducing the frequency of caesarean section in order to prevent its great complications. This systematic review has been designed to review clinical studies that investigate the effects of date palm fruit on labor outcomes (duration of labor stages, bishop score, and frequency of cesarean section) compared with routine cares. Methods: This study was performed in 2019. Required data has been collected from electronic databases and manual searches. All randomized clinical trials evaluating the effects of date palm fruit on labor and delivery that were published from January 2000 to August 2019 in English and Persian languages, were incorporated in this systematic review. The methodological quality of the included studies was evaluated according to the risk of bias assessment of Cochrane handbook of systematic reviews, and were then reported using Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. Results: Eight studies were included in the qualitative and quantitative synthesis. Meta-Analysis showed that date fruit consumption can significantly reduce active phase of labor (three trials with 380 participants; (MD= -109.3, 95%CI (-196.32, -22.29; I2=89%), P=0.01), and also it can significantly improve the bishop score (two trials with 320 participants; MD = 2.45, 95%CI (1.87, 3.04; I2=0%), P<0.00001). Date fruit consumption had no effects on the duration of first, second, and third stages of labor, and the frequency of cesarean section. Conclusion: Date can reduce the duration of active phase and improve the bishop score; however, due to from the low to mediate quality of the studies; it seems that the other studies are needed to prove these results better than this.

Nutraceutical Properties

Many recent studies in the field of cosmetics have focused on organically sourced substances. Products made from organic materials are safe, high quality, cruelty-free, and more effective than those made from synthetic materials. Many organic compounds are known to be physiologically active in humans and have an extended storage capacity and long-lasting environmental effects. Agro-industrial waste has recently increased substantially, and the disposal of date palm waste, often performed in primitive ways such as burning, is harmful to the environment. Fruit processing industries generate over 10% of the total date seed waste daily, which could be converted into useful food products. Date fruit and seed are rich in sugar, vitamins, fiber, minerals, and phenolic compounds with antioxidant and anti-inflammatory properties that significantly promote human and animal health. This waste is rich in bioactive compounds and essential oils used in many kinds of food, medicine, and cosmetics. Most active cosmetic ingredients come from natural sources such as fruit, fish, and dairy, and recent research shows that date extract and seed oil help to reduce melanin, eczema, acne, and dry patches, while increasing skin moisture and elasticity. This review details the bioactive compounds and nutraceutical properties of date fruit and seed, and their use as cosmetic ingredients.

Background: Formaldehyde (FA) is one of the most widely used materials in industries and in sciences. Prolonged contact with FA might have harmful effects on fertility due to the increase in the reactive oxygen species level. On the other hand, date palm (Phoenix Dactilifera L.) fruit extract (DPFE) contains a high concentration of natural antioxidants that could scavenge free radicals. Objective: The aim was to investigate the prophylactic effects of DPFE, with strong antioxidant properties, on FA-induced testicular toxicity in male mice. Materials and Methods: Thirty-two adult NMRI male mice with a weight range of 25- 35 gr (9-10 wk old) were randomly divided into four groups: control group (distilled water, orally for 35 days), FA group (FA; 0.25 mg/kg intraperitoneally (i.p.) for 20 days), treatment group (Date (DT) + FA; DPFE, 4 mg/kg for 35 days followed by FA administration, 0.25 mg/kg, i.p., for 20 days), date fruit extract group (DT; DPFE, 4 mg/kg, orally for 35 days). After this, blood was collected and left epididymis and testis tissues were isolated to evaluate the sperm parameters and histological examination, respectively. Results: The FA administration increased the sperm morphological anomalies and reduced the sperm count, viability and motility, and also testosterone compared to the control group (p ≤ 0.001). In addition, histological studies of the testes showed that FA causes changes in the testis seminiferous tubules such as destruction of germinal epithelium and vacuolization of the tubules. The DPFE consumption before FA administration could partially ameliorate the reduced testosterone, sperm, and testicular parameters due to FA. Conclusion: The DPFE use might have discount effects on FA-induced testicular toxicity. Key words: Formaldehyde, Date fruit, Testis, Toxicity, Sperm, Testosterone.

Background: Alzheimer's disease (AD) is a neurodegenerative disorder marked by brain inflammation resulted in structural damage and brain dysfunction. Tumor necrosis factor α (TNFα) is a cytokine that plays an important role in inflammation. Dates fruit may help to fight oxidative stress and inflammation in the brain. Objective: To determine the effect of date fruit extracts on blood TNFα levels and brain weight of alzheimer’s model rats. Methods: This research is a laboratory experimental study by post-test only with control group design using alzheimer model rats. This study used 6 treatment groups with simple randomization. Each treatment group was represented by 8 Sprague Dawley rats. The normal control group (KN) was not induced by Hcy and was not given date palm extract, the negative control group (K-) was the Alzheimer's experimental rats which was not given the date palm extract, the positive group was the Alzheimer's experimental rats which was given the Donepezil (K+). Groups P1, P2, P3 were Alzheimer's experimental rats that were given date palm extract at a dose of 200, 400,800 mg / kgBW / day. The effect of date palm extract dosage on TNFα levels and brain weight were analyzed using the One Way Anova test followed by Tukey's post hoc test. Results: The difference in TNFα levels between groups showed a significant difference (p = 0.00). Meanwhile there was no significant difference in brain weight among all groups (p > 0,05). Conclusion: Date palm extract at doses of 200, 400, 800 mg / kgBW can decrease blood TNFα levels of Alzheimer’s model rats.

Production of highly soluble date sugar powder from the nutritive date fruits will be a suitable and superior alternative to commercial refined sugar, providing sustainability in date palm cultivation. A good understanding of the nutritional and phytochemical composition of date fruits is imperative for this purpose. In this work, 11 different date fruit species commonly cultivated in the United Arab Emirates were studied for their chemical composition, physical properties, amino acids, minerals, and anti-nutritional contents. The results revealed that the date fruits contain moisture, protein, lipid, and ash content in the ranges of 14.8%–20.5%, 2.19%–3.12%, 0.25%–0.51%, and 1.37%–1.97%, respectively. Potassium was identified as the major microelement in all the date varieties. Amino acid assay depicted that the date fruits mainly contained glutamine and aspartic acids, along with other essential acids. Monosaccharides (glucose and fructose) were more prevalent in the date fruits than polysaccharides (sucrose), exhibiting the potential of date fruit for non-diabetic sugar production. Phytoconstituents present in date samples, such as flavonoids, oxalates, tannins, saponins, alkaloids, and cyanides, were also evaluated and reported. Results showed that although all date fruit varieties were nutritious, they contain significant variation in their nutritional, physical, elemental, and phytochemical properties.

Maturation Stages

Some parameters related to nutritive and functional properties were evaluated in date fruit from seven date palms from the Elche grove along the maturation process, in order to obtain information about differences due to phenotypic variability. Results showed that sugar and organic acid concentration were different depending on date palm, the highest levels being reached at 100% Rutab stage, with glucose and fructose as the predominant sugars and malic acid as the major organic acid. Hydrophilic total antioxidant activity (HTAA) was high and correlated to phenolic content, with maxima levels being found at early, medium or late Khalal stages, depending on date palm. In addition, significant differences were found in both, phenolic concentration and HTAA among date palm and maturation stages, while lipophilic total antioxidant activity (LTAA) was very low, without changes along maturation and not correlated to HTAA. Then, date fruit from Elche grove could serve as a good source of natural antioxidant and it would be advisable to consume them at medium or late Khalal stages, in order to achieve the maxima nutritional (high concentration of sugars and organic acids), organoleptic (appropriated firmness levels, yellow or red color and low astringency) and functional properties with benefits to human health.
