“…Metabolic profiling of 12 cultivars of date ( Phoenix dactylifera L.) fruits from Saudi Arabia showed that the chemical composition and nutritional values were different among the cultivars, also, principal component analysis (PCA) and hierarchical cluster analysis (HCA) separated the cultivars into distinctive groups (Hamad et al, 2015). Moreover, primary and secondary metabolites, vitamins, minerals, and biological activities were different among the date palm cultivars (AbdElgawad et al, 2019).…”

Balanites aegyptiaca L. is a multipurpose tree distributed in Africa and Middle East. Several parts of B. aegyptiaca have been suggested to have medicinal uses. So far the effect of ecological origin on the nutritional values and biological activities of B. aegyptiaca genotypes is rarely investigated. Further, metabolic profiling and assessment of the functional food value of B. aegyptiaca leaves are far from complete. In this study, biological activities and profiling of primary and secondary metabolites were investigated in the leaves of five B. aegyptiaca provenances collected from Egypt, Sudan, Saudi Arabia, and Yemen. Interestingly, all provenances showed notable antidiabetic, antioxidant, antiprotozoal, antibacterial, antifungal, and anticancer activities. Hierarchical clustering analysis revealed significant variability in the concentrations of individual sugars, organic acids, amino acids, fatty acids, vitamins, phenolics, and minerals among the provenances and these variations were provenance dependent. Medina provenance showed the heights diphenylpicrylhydrazyl (DPPH) scavenging and antifungal activities and was the most powerful against embryonic kidney adenocarcinoma and urinary bladder carcinoma cells. The highest inhibition against Escherichia coli and colon carcinoma cells was observed by Sudan and Cairo provenances. El‐Kharga and Yemen provenances showed the greatest activity against Trypanosoma cruzi and hepatocellular and urinary bladder carcinoma. Therefore, leaves of B. aegyptiaca possess good nutritive and biological capacities and might have potential applications in the food and medical industries. However, the strength of such activities is significantly affected by the provenance. Practical applications According to the national Research Council (NRC) of United States, Balanites aegyptiaca L. is recognized among the 24 priority lost crops of Africa. B. aegyptiaca leaves contain considerable amounts of primary metabolites (e.g., sugars, EAAs, USFAs) and secondary (e.g., phenolic acids and flavonoids) metabolites, vitamins, and macro and microelements. The obvious existence of these nutritionally and medicinally related compounds supports the functional food value of B. aegyptiaca leaves. Moreover, the present results revealed that B. aegyptiaca is not only a foliage dietary plant, but also could be considered as a valuable source for neutraceuticals, which support its pharmacological value. So far, this is the first report to explore, in detail, the functional food value of B. aegyptiaca leaves by presenting a clear image about its metabolic profiling and biological activities, and how the provenance factor could affect these values.

“…In case of fatty acids, NIST 05 database and Golm Metabolome Database (http://gmd.mpimp-golm.mpg.de) were used for identification. According to AbdElgawad et al (2019), total sugars, phenolics, and flavonoids were extracted and assayed following Nelson's, Folin–Ciocalteu and aluminum chloride calorimetric assays, respectively.…”

“…They are known to have various biological activities such as antioxidant, antimicrobial, anti-inflammatory and anticancer properties [ 2 ]. Recently, a priority was given to herbal plants in terms of enhancing the production of the economically important phytochemicals through the application of cultivation procedures under stimulated growth conditions [ 3 ]. In this aspect, arbuscular mycorrhizal fungi (AMF) have been regarded as one of the most important beneficial microorganisms that are able to associate with almost two thirds of terrestrial plants improving their growth and stress tolerance [ 4 ].…”

Arbuscular mycorrhizal fungi (AMF) and elevated CO2 (eCO2) have been effectively integrated to the agricultural procedures as an ecofriendly approach to support the production and quality of plants. However, less attention has been given to the synchronous application of AMF and eCO2 and how that could affect the global plant metabolism. This study was conducted to investigate the effects of AMF and eCO2, individually or in combination, on growth, photosynthesis, metabolism and the functional food value of Thymus vulgare. Results revealed that both AMF and eCO2 treatments improved the photosynthesis and biomass production, however much more positive impact was obtained by their synchronous application. Moreover, the levels of the majority of the detected sugars, organic acids, amino acids, unsaturated fatty acids, volatile compounds, phenolic acids and flavonoids were further improved as a result of the synergistic action of AMF and eCO2, as compared to the individual treatments. Overall, this study clearly shows that co-application of AMF and eCO2 induces a synergistic biofertilization impact and enhances the functional food value of T. vulgare by affecting its global metabolism.

“…Finding renewable, cheap, and natural materials have extensively increased and biopolymers have over passed these types of material [1][2][3][4]. The most elegant biopolymer is chitin that is found in the cell walls of yeast, and fungi exists in lower plant and animal kingdoms but presently the main source of chitin is the shells of marine living organisms such as shells of crabs and shrimps.…”

Modification of chitosan any Schiff base reaction with acetophenone derivatives was done. Fourier transformer infrared analysis (FT-IR), scanning electron microscope (SEM), and X-ray diffraction (XRD) were used as the appropriate characterize the Schiff base derivatives. Thermal behavior of the prepared materials was also studied. Various biological activities were examined for the prepared materials antimicrobial activity including antibacterial (studied against Streptococcus sp. Bacillus subtilis and Sarcina lutea as an example for gram-positive bacteria and Pseudomonas aeruginosa and Escherichia coli as an example for Gram-negative bacteria), anti-fungal (against Candida albicans) and anti-protozoal (against Trypanosoma cruzi and Leishmania donovaniwas). Antioxidant activity of chitosan and its Schiff base derivatives was detected using the FRAP and DPPH techniques. Colon carcinoma (Colo 205), hepatocellular carcinoma (Hep G2), urinary bladder carcinoma (T24P) and embryonic kidney adenocarcinoma (293) used to examine the anticancer activity of chitosan and its modified derivatives. The new chitosan Schiff base derivatives showed superior anti-bacterial, antifungal, anti-protozoal and antioxidant activity than parent chitosan. But in case of anticancer test of HebG2 and T24P chitosan was more effective than the modified derivatives.
