Preliminary Evaluation of the Effect of Domestication on the Marketable and Nutritional Quality of B. aegyptiaca (L.) Delile Oil from Algeria.

Balanites aegyptiaca is a multipurpose fruit tree that grows wild in many arid and semi-arid African areas; however, recent domestication efforts have been undertaken to protect the species from the threat of urbanization and climate change. Within this context, the impact of the domestication of Algerian B. aegyptiaca was evaluated on its seed oil, which is already valued as food. Hence, oils from wild and domesticated trees were comparatively investigated for their physicochemical and compositional quality. Both oil types had a good oxidative stability and met the requirements for human consumption in terms of the saponification index, the free acidity, and the peroxide value. Moreover, they showed a comparable FA composition, with high levels of oleic and linoleic acids, which are beneficial for the consumer's health. Domestication led to a statistically significant decrease in the tocopherols and polyphenols in the oil. The phytosterols and squalene were slightly lower in the domesticated oil than in the wild relative, although no statistically significant differences were observed. A comparable mineral profile was revealed and the minimal variations in the trace elements between the oils could be related to the natural variability in the seeds. Hopefully, this study will encourage the domestication of B. aegyptiaca as a sustainable strategy for enhancing its socioeconomic value in Algerian rural areas.

Capturing CO2 through High Surface Area Activated Carbon Derived from Seed Shells of Balanites Aegyptiaca.

Activated carbon is an attractive adsorbent for capturing various environmental pollutants, including CO2. Herein, an optimal synthesis and impressive performance of activated carbon made from Balanites aegyptiaca (Desert date) seed shells is reported, which is an abundant agricultural waste in the Middle East and Africa. The synthesis route involved pretreating the biomass with KOH and heating it under a suitable temperature profile. An optimal KOH-to-biomass ratio and multi-stage carbonization yielded activated carbon with a surface area above 3000 m2/g and an average pore size of nearly 4.1 nm. At 0 °C, this activated carbon exhibited CO2 uptake of 11.3 mmol g-1 that surpassed the uptake capacity of previously reported activated carbons. The selectivity towards CO2 was also found to be significantly higher compared to other gases. Thus, the present approach demonstrates an efficient conversion of agricultural waste to activated carbon for capturing CO2 and other environmental contaminants.

Critical Review on Balanites aegyptiaca Delile: Phytoconstituents, Pharmacological Properties and Nanointerventions.

Balanites aegyptiaca Delile (BA) is an enduring xerophytic woody and spinous flowering tree and is commonly known as desert date or Ingudi (Hingot). It belongs to the family Zygophyllaceae, which is specific to be drought areas of Nigeria, Africa, South Asia and India (Rajasthan). In Ayurveda, this traditional medicinal plant is reported for the management of jaundice, syphilis, yellow fever, metabolic disorders, liver, and spleen problems. The main aim of the review is to compile its medicinal uses and further advancements to showcase the promises inherited in various parts of the plant for the benefit of mankind. As per the literature survey, various researchers have focused on the detailed investigation of BA including the phytopharmacological evidence, chemical constituents, nano-formulations, commercialized products, and clinical trials. Several remarkable scaffolds and isolated compounds like diosgenin, yamogenin, balanitin1/2, balanitin 3, bal4/5, bal6/7, rutin-3-glycosides, 3,7-diglycosides, (3, 12, 14, 16)-(12-hydroxycholest-5-ene-3,16-diyl-bis)-D-glucopyranoside and balanitoside have been identified. Additionally, this traditional plant has been scientifically proven by in vitro and in vivo. Based on the complete review of this plant, most of the compounds have been isolated from the fruit and kernel part. Additionally, based on the literature, a histogram was developed for pharmacological activity in which antidiabetic study was found to be more compared to other pharmacological activity. As a spinous desert dates, this plant needs to be explored more to bring out newer phytochemicals in the management of various diseases.

Fourier transform infrared spectroscopy as a tool for identifying the unique characteristic bands of lipid in oilseed components: Confirmed via Ethiopian indigenous desert date fruit.

Searching for good sources of value-added lipids that can be utilized for industrial and domestic applications is getting a fast-growing attention. Hence, the exploitation of underutilized fruit species for oil production is of particular care. But, rapid and accurate characterization of oil-bearing biomass before considering it as an alternative source is essential to know the properties of interest which significantly influence biomass conversion. Instead of testing oilseed components to know their lipid reach part via extractive techniques, one of the rapid analysis methods is Fourier transform infrared spectroscopic approach. Thus, this paper aims to identify the unique characteristic bands of lipids in oilseed components confirmed via Ethiopian desert date fruit (i.e., mesocarp, endocarp, kernel and oil). While all parts of the fruit were subjected to oil extraction, it was proved that the only fatty portion containing about 40.32% wt of lipid was in its kernel. Accordingly, the only functional groups observed in the oil-rich part include = C-H stretching at 3006/7 cm-1 in aromatic and olefins of unsaturated fatty acid, symmetrical C-H stretching of aliphatics in the -CH3 groups at 2853 cm-1, C-O stretching in esters due to asymmetric vibrations of C-C(=O)-O bonds at 1159/66 cm-1, and C-H rocking vibration of methylene in alkanes at 718/23 cm-1.

Phytochemicals, Antioxidant Activity and Ethnobotanical Uses of Balanites aegyptiaca (L.) Del. Fruits from the Arid Zone of Mauritania, Northwest Africa.

Phytochemicals and antioxidant activity of fruits of 30 B. aegyptiaca trees naturally growing in the hyper-arid and arid zones in Mauritania were evaluated by following standard procedures. Ethnobotanical uses of fruit pulps and kernel were assessed using a structured questionnaire. Balanites aegyptiaca fruit pulp is a good source of sugars (33 g/100 g dry matter (DM)), polyphenols (264 mg GAE/100 g DM) and flavonoids (34.2 mg/100 g DM) with an average antioxidant activity of 519 µmol TEAC/100 g DM. The fruit kernel is rich in lipids (46.2 g/100 g DM) and proteins (29.5 g/100 g DM). Fruits from the hyper-arid zone exhibited high level of polyphenols, antioxidant activity and soluble tannins. Almost all of the informants (97.14%) reported the use of fruit pulp in folk medicine to treat diabetes, while 72.86% reported using the fruit pulp to treat hypertension. Kernel oil is mainly employed as ointments in the treatment of paronychia (57.14%) and dermal infections (35.71%). The predominant methods for preparing/administering fruit pulp/Kernel were maceration (58.8%), sucking fruit pulp (25.7%) and decoction (24.2%). Balanites aegyptiaca fruit contain both nutritional and health-promoting phytochemicals that could be of interest in the development of strategies for sustainable use of this neglected indigenous fruit tree.

In vitro and in vivo antidiabetic potential of extracts and a furostanol saponin from Balanites aegyptiaca.

CONTEXT: Balanites aegyptiaca Del. (Zygophyllaceae) fruits are well-known antidiabetic drug in Egyptian folk medicine. Nevertheless, its mechanism of action is still unclear. OBJECTIVES: Searching for the possible mechanisms of action of the plant and identification of its bioactive compounds. MATERIALS AND METHODS: A bio-guided protocol based on the evaluation of α-glucosidase (AG) and aldose reductase (AR) inhibitory activities was adopted to isolate the biologically active compounds from the methanol extract (MeEx). An in vivo antidiabetic study was conducted for the active extract, fraction and compound using streptozotocin-induced diabetic male albino Wistar rats at two dose levels (100 and 200 mg/kg.b/wt) for 2 weeks. RESULTS: Three compounds were isolated and identified: a sterol, (1) stigmasterol-3-O-ß-d-glucopyranoside; a pregnane glucoside, (2) pregn-5-ene-3ß,16ß,20(R)-trio1-3-O-ß-d-glucopyranoside; a furostanol saponin, (3) 26-(O-ß-d-glucopyranosyl)-22-O-methylfurost-5-ene-3ß,26-diol-3-O-ß-d-glucopyranosyl-(1 → 4)-[α-l-rhamnopyranosyl-(1 → 2)]-ß-d-glucopyranoside. Only compound 3 possessed significant AG and AR inhibitory activities (IC50 = 3.12 ± 0.17 and 1.04 ± 0.02 µg/mL, respectively), while compounds 1 and 2 were inactive. The in vivo antidiabetic study revealed that MeEx and furostanol saponin 3 possessed significant activities at a dose of 200 mg/kg through reducing the fasting plasma glucose level by 46.14% and 51.39%, respectively, as well as reducing the total cholesterol by 24.44% and 31.90%, respectively. Compound 3 also caused increment in insulin and C-peptide levels by 63.56% and 65%, respectively. DISCUSSION AND CONCLUSIONS: We presented a scientific base for using Balanites aegyptiaca, and shed the light on one of its saponins, as an antidiabetic agent in fasting and postprandial hyperglycaemia along with the improvement of diabetic complications.
