“…The high saponification values of date seed oils indicate that date seed oils have low molecular weight triglycerides. They are similar to the saponification values of Tamdjouhert, Deglet Nour, Majhoul, and other some date seed oils (Bouhlali et al, ; Boukouada & Yousfi, ; Nehdi, Omri, Khalil, & Al‐Resayes, ). The oil contents of date seed were found between 5.77 (Majhoul) and 10.71% (Allig).…”

“…Their distributions of results changed depending on date varieties and locations which harvested. In previous study, Bouhlali et al () reported that three date seed (Boufgous, Bousthammi, and Majhoul) oils contained 44.92–48.38% oleic, 16.74–20.34% lauric, 10.23–12.28% myristic, 9.82–10.91% palmitic, 8.8–9.02% linoleic, and 2.86–3.73% stearic acids ( p < .05). These findings are very similar to the results reported by Al Juhaimi et al (), Besbes et al (), Al‐Hooti et al () and Sawaya, Khalil, and Safi ().…”

The acid value of date seed oils were determined between 1.09 mg KOH/g (Taleese) and 1.44 mg KOH/g (Ghars). Iodine values of oil samples changed between 67.18 g I2/100 g (Allig) and 71.23 g I2/100 g (Deglet Nur) (p < .05). Oleic, linoleic, lauric, palmitic, myristic and stearic acids were the key fatty acids of date seed oils. Among fatty acids determined, oleic was the predominant fatty acid (39.7–49.7), followed by lauric (9.7–24.6%), myristic (7.3–12.8%), palmitic (7.8–14.2%), linoleic (6.2–17.3%) and stearic acids (1.3–4.9%) (p < .05). The predominant tocopherol was α‐tocotrienol (31.76–37.41 mg/100 g oil), followed by ɣ‐tocopherol (7.61–11.84 mg/100 g), ɣ‐tocotrienol (4.27–8.47 mg/100 g oil), δ‐tocopherol (1.13–2.81 mg/100 g), and β‐tocopherol (0.69–1.33 mg/100 g oil) (p < .05). While gallic acid contents of date seeds change between 2.43 (Boufgous) and 6.91 (Dore), syringic acid contents changed between 1.28 (Talees) and 4.86 (Adwi) (p < .05). In addition, catechin contents of date seeds changed between 2.86 (Dora) and 7.23 (Ghars). Practical applications Date is an important plant in some countries. Date seed is a waste product of many date products such as pitted dates, date powders, date syrup, date juice, and date confectionery. The ground and roasted seeds are used as plain or mixed with coffee. In addition, date seeds are used for animal feed in the cattle, fish, sheep, camel, and poultry industries. Also, the date and their derivatives are rich in nutraceuticals, pharmaceuticals, and medicine.

“…[3,4] The production and utilization of dates increases due to its beneficial value and the nonedible contents (seed) from them can also be used in making noncaffeinated coffee and animal feeding. [5] Date seed improves the functionality of the immune system and may also lower the risk of cancer and cardiovascular conditions as it contains high amount of phenolic content and nutritional compounds such as fiber, fat, moisture, protein, ash, and vitamins. [5,6] In traditional medicine, the powdered form of date seeds is used as an ingredient for relieve ague and toothaches and also used as a folk remedies for dealing liver diseases, diabetes, and gastrointestinal disorders.…”

Aim: This study was carried out to investigate the anticancer and antibacterial activity of date seeds and its phytochemical composition. Materials and Methods: Qualitative phytochemical screening was performed using date seed powder using biochemical assays. Gas chromatography-mass spectrometry (GC-MS) analysis was performed to identify the phytochemical contents in the extract. MTT assay was carried out to study the cytotoxicity of the seed extracts against HCT-15 (human coloretal cancer) cells. Antibacterial activity was studied using agar well diffusion method, against Bacillus cereus and Escherichia coli. Results: GC-MS analysis of acetone and chloroform extract of date seeds suggests that acetone extract contains majorly of aliphatic molecules and chloroform extract contains aromatic molecules. Cytotoxicity study showed that acetone extract is highly cytotoxic with inhibitor concentration 50 (IC50) value at 20 µg/ml and chloroform extract is moderately cytotoxic with IC50 value at 100 µg/ml concentration against HCT-15 cells. Antibacterial study showed that chloroform extract had no antagonistic activity against bacteria, whereas acetone extract demonstrated significant antibacterial activity with a zone of inhibition of 17 mm and 20 mm against B. cereus and E. coli, respectively at 1 mg/ml concentration. Conclusion: Results of this study conclude that acetone extract of date seeds (Phoenix dactylifera L) contains significant potential for pharmaceutical applications, in the field of antibacterial and anticancer drug discovery.

Since ancient times the oil from date palm pits (Phoenix dactylifera L.) has been used to heal wounds. In order to prove this traditional usage of the pits, this oil was extracted from the pits of the Tunisian cultivar 'Alig' and its physico-chemical properties and the chemical composition were evaluated. The fatty acid profile, evidenced by GC, allowed to classify this oil as an oleic-myristic acid oil with a clear abundance of oleic acid (53.66 %). 1 H and 13 C-NMR as well as FT-IR analyses confirmed the presence of fatty acids in triglyceride forms. Furthermore, in vivo wound healing activity of a cream formulated from the extracted oil was performed, for the first time, using a rat model and was compared to placebo cream and a commercial formulation, MEBO®. This study showed that the test cream promoted the healing of pressure ulcers better than the placebo cream and the MEBO® ointment. The results showed that this vegetable oil is able to improve the healing of infected wounds in rats, thus supporting its traditional use. The contribution of the main oleic, linoleic and myristic acids that can be derived from enzymatic hydrolysis to the healing activity of the whole pits oil was predicted by in silico study and the calculated pharmacokinetics parameters.
