“…In another study, it was suggested that date seed oil as a by-product helps to stabilize the protection of edible oils from oxidation, due to its high content of polyphenols. She also indicated that the date seed oil has a sharp yellow color compared to other vegetable oils, and this gives it the advantage of protection from ultraviolet rays and the protection of skin cells, based on that it was nominated for use in the production of cosmetics (El-Massry et al, 2019). Vinegar is also produced by the alcoholic fermentation of a sugary date solution.…”

Dates are one of the most prominent types of fruits spread in the Middle East and North Africa and have been an essential part of thediet of the Arab world since ancient times. It has been called “nature’s candy” due to its sweet taste, which is attributed to its high sugarcontent. Date fruits have great nutritional and therapeutic value, due to the variety of elements they contain, as they contain a goodpercentage of fiber, vitamins, and minerals, especially magnesium, potassium, selenium, calcium salts, and fatty acids (lauric, linoleic,palmitic, and citric acid) as well as an excellent source of antioxidants (flavonoids, polyphenols, and carotenoids) which offer significanthealth-promoting and disease-fighting benefits. In this review, the origin of the date palm fruits was studied, and the nutritional valuewas compared between three types of dates (Ruthana, Sukari, Ajwa) in terms of the nutritional components and the therapeutic values,which is proven by several studies. The nutritional content of date fruits; sugars, beneficial fats, nutritious proteins, and phytochemicalswas reviewed. The health benefits of date fruits include their ability to inhibit free radicals, anti-inflammatory activity, cytotoxicity oncancer cell lines, and the applications for its use as a functional food were indicated. The exact mechanisms still need further researchand exploration, specifically, Ruthana fruits as this type of available literature showed a research gap that could be investigated

“…A study on date palm seed steeping against free radical products (MDA) and antioxidant vitamins (vitamin E) in the alloxan induced rat model has revealed that date palms seed could successfully decrease the levels of MDA and uplift the vitamin E levels (Saryono et al, 2017). The findings of a study showed that having high relative percentages of oleic acid and conferring protection against UV light to prevent cellular damage make date seed oil a promising candidate for use in cosmetics and food industries (El-Massry et al, 2019). Paraoxonase 1 (PON1) is a high-density lipoprotein (HDL)-associated antioxidant enzyme which is produced in the liver.…”

Many natural products such as fruits and vegetables are promising amends as safe, effective and affordable approaches to control cancer development and progression, since they are inexpensive and available without any hazards. For instance, the aqueous extract of Ajwa dates (Phoenix dactilyfera) has been found to improve liver function through the restoration of anti-oxidant enzymes, liver enzymes, and cytokines balance and gene expression to normal levels. As the treatment and prognosis of Hepatocellular carcinoma, one of the leading causes of cancer associated deaths globally, has been found to be better if the liver function of the patient can be preserved, Ajwa date extract has been used together with the conventional therapeutics for the treatment of this disease. However, no study has been conducted so far on the anticancer activity of Bangladeshi wild date palm fruits (Phoenix sylvestris) despite the fact that it contains apigenin, quercetin, glucans, luteolin, and iron and vitamin complex. Therefore, in this review we discussed an idea that potential anticancer agents can be isolated from the extract of these fruits, which can eventually be used as an indigenous substance for the treatment of Hepatocellular carcinoma in our country and also the liver cancer inhibitory effects of the aqueous extract of these dates can be evaluated in rat model.

Managing Encapsulated Oil Extract of Date Seed Waste for High Hydroxyl Radical Scavenging Assayed via Hybrid Photo-Mediated/Spectrofluorimetric Probing

This work addresses two research topics: the first concerns the specific/sensitive trapping of hydroxyl radicals (•OH), and the second concerns the efficacy of encapsulating natural antioxidants, potentially lengthening their preservation activity. For context, nano-titania was solar-irradiated to produce •OH, which was spectrofluorimetrically assessed, based on the selective aromatic hydroxylation of the non-fluorescent sodium terephthalate to 2-hydroxyterephthalate fluorophore. Fluorescence intensity is proportional to generated •OH. Thus, a simple/rapid indirect method was utilized to assess •OH precisely. Accordingly, novel photoluminescent system is outlined in order to assess the scavenging potentiality of •OH in date seed oil (DSO) in both its pure and encapsulated formulations (ECP–DSO), i.e., when fresh and 5 months after extraction and encapsulation, respectively. With the addition of 80 μg/mL DSO or ECP–DSO, the efficacy of •OH scavenging amounted to 25.12 and 63.39%, which increased to 68.65 and 92.72% when 200 μg/mL DSO or ECP–DSO, respectively, was added. Moreover, the IC50 of DSO and ECP–DSO is 136.6 and 62.1 µg/mL, respectively. Furthermore, DSO and ECP–DSO decreased the kinetics for producing •OH by ≈20 and 40%, respectively, relative to •OH generated in the absence of antioxidant. This demonstrates the benefits of encapsulation on the preservation activity of natural antioxidants, even after five months after extraction, in terms of its interesting activity when compared to synthetic antioxidants. The developed fluorimetric •OH probing upgrades antioxidant medicines, thus paving the way for theoretical/practical insights on mechanistic hydroxyl radical-damaging biology.
