Abstract:In Aspergillus flavus Link, the total lipid, sterols, neutral lipids, phospholipids and fatty acid content decreased significantly with the application of different concentrations of Ephedra alata Decne. extrtact. Gas chromatographic analysis revealed the presence of 12 fatty acids namely, (caprylic (C8), capric (C10), lauric (C12), myristic (C14), palmitic (C16), palmitoleic (C16:1), stearic (C18), oleic (C18:1), linoleic (C18:2), ? linolenic (C18:3), arachidic (C20) and arachidonic (C20:4) with total un-satu… Show more
“…Ephedra alata was globally used in folk medicine, especially its stems, as a decoction of these stems were used as a stimulant, treatment for kidney health problems, bronchial asthma, circular system disorders, and digestive system disturbances, as well as for treatment of cancer. Also, the plant stems are chewed to treat bacterial and fungal infections—especially in oral bacterial and fungal infections [ 5 , 6 ]. Fig.…”
Background
Discovering and screening for potential anti-obesity, anti-diabetic, anticancer, and antioxidant treatments from natural products still in recent times the main goal for many pharmaceutical scientists. The present investigation aimed to evaluate the chemical constituents of Ephedra alata fruits various extracts and to assess their antioxidant, antiobesity, antidiabetic, and cytotoxic effects.
Result
In this work, high content of flavonoids and phenols were observed in the methanol fraction of E. alata fruits, which reached 98.95 mg of RUE/g and 33.22 mg of GAE/g, respectively. The methanol fraction has significant inhibitory activity against DPPH, α-amylase, α-glucosidase, and lipase with an IC50 value of 1.07, 9.43, 46.16, and 66.48 µg/mL. respectively. Also has anticancer activity against HeLa cancer cell line. While the acetone fraction has potent antioxidant activity with IC50 5 µg/mL.
Conclusion
The DPPH and digestive enzymes assays results showed that the methanolic fraction of E. alata fruits has potent antioxidant, anti-diabetic, and anti-obesity activities, which can be an excellent candidate for biological and chemical analysis and can be further subjected for isolation of the therapeutically active compounds with anticancer potency.

“…The decoction of E. alata stem is used in the folk medicine as a potential stimulant, deobstruent, to treat different disorders (e.g. kidney, bronchi, circular system, digestive system disorders), to relief asthma attack and as antifungal (Al-Qarawi, Abd Allah, & Abeer, 2012). It is also used in cancer treatment and the plant stems are chewed to treat bacterial and fungal infections (Jaradat et al, 2015).…”
Scientific research has been focused on finding natural occurring molecules from plant origin. Herein, infusion, decoction and hydroethanolic extracts of Thymus algeriensis Boiss. & Reut. and Ephedra alata Decne. from Algeria were phytochemically characterized by LC-DAD-ESI-MSn, and evaluated regarding bioactive properties (antioxidant and antibacterial). Flavonol and flavone glycoside derivatives and phenolic acids, specially rosmarinic acid and kaempferol-O-glucuronide were the major compounds in T. algeriensis extracts. Otherwise, E. alata presented isoflavones and flavonol derivatives as main compounds, being hydroxypuerarin isomer 1 the major molecule. Aqueous extracts had significantly higher antioxidant activity, being this activity correlated with the amount of phenolic compounds. Antimicrobial activity of the extracts was tested against multi-resistant bacteria strains from clinical isolates. The obtained MIC values indicate that the hydroethanolic extracts revealed the highest effect, especially the one of T. algeriensis against Gram-positive bacteria. Hence, these plant extracts could be used in the development of bioactive ingredients.
“…This species is mainly distributed in arid environments, often near shifting sand dunes of Iran, Algeria, Iraq, Chad, Egypt, Palestine, Lebanon, Jordan, Saudi Arabia, Morocco, Syria, Libya, Mauritania, Mali, Somalia, and Tunisia, where it grows wildly on the gravely rocky, sandy, and clay soil [8]. The decoction of E. alata stem is used in folk medicine as a potential stimulant, to treat different disorders (e.g., kidney, bronchi, circular system, digestive system disorders), to relieve asthma attack, and as antifungal [9]. The plant stems are usually chewed to treat bacterial and fungal infections [10].…”
In this study, the physicochemical characterization, functional properties, and antioxidant activity of polysaccharides extracted from Ephedra alata (EAP) were investigated. EAP were extracted in water during 3 h with a liquid/solid ratio of 5 in a water bath at 90 °C. The structure of the extracted EAP was examined by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and gas chromatography-mass spectrometry (GC-MS). The functional properties and biochemical activities of EAP were determined. The chemical analysis revealed that the contents of carbohydrates, uronic acid, and proteins were 73.24% ± 1.24%, 6.82% ± 0.57%, and 6.56% ± 0.36%, respectively. The results showed that the extracted EAP essentially contain three functional groups: C=O, C-H, and O-H. SEM images showed that EAP present numerous high porosity particles. The monosaccharide composition revealed a polymer composed of glucose (43.1%), galactose (36.4%), mannose (14.9%), arabinose (3.7%), and gluconic acid (1.7%). EAP showed interesting functional properties (solubility, oil holding capacity, foaming and emulsion properties). Finally, the results revealed that EAP displayed excellent antihypertensive and antioxidant activities. Overall, EAP present a promising natural source of food additives, antioxidants, and antihypertensive agents.
