“…The biological activity of plants might be ascribed to the presence of secondary metabolites like polyphenols, flavonoids, lignins, alkaloids, terpenoids, carotenoids, vitamins, etc. (Vinson et al, 2005;Zaki et al, 2016;Zaki et al,2017).…”

The objective of this study was to analyze the phytochemicals and to determine the antioxidant, antibacterial and allelopathic potential of three wild Mesembryanthemum species (M. crystallinum L., M. forsskaolii Hochst. Ex Boiss and M. nodiflorum L.). The phytochemical composition of the methanolic extract of studied species revealed the considerable quantities that might be responsible for their powerful antioxidant activity. The IC50 values were 386.51, 592.97, and 752.23µg/ml for M. nodiflorum, M. crystallinum and M. forsskaolii extracts respectively. The antibacterial activity index was calculated for each extract in comparison with the standard antibiotics. M. nodiflorum showed higher potency than ampicillin and penicillin G against against Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis. The allelopathic potential showed that the studied Mesembryanthemum species expressed a significant phytotoxic activity against Chenopodium murale weed in a dose dependent manner. M. nodiflorum sample showed the most phytotoxic effect among the studied species.

“…Most plants carry a large number of unidentified compounds which can be really useful for making new drugs. Therefore, today efforts have been directed towards the discovery, isolation and development of natural products from various medicinal plants and animal sources [13][14][15][16]. The objectives of this research were to determine the proximate composition, mineral content and secondary metabolites of three wild medicinal species of genus Fagonia naturally growing in the different habitats of study area to evaluate their economic potentialities and to use them in various purposes as a raw natural resource.…”

Proximate composition of the aerial parts of three Fagonia species (Fagonia arabica L., F. mollis Delile and F. cretica L.) collected from different habitats were analyzed. Macro- and micro-elements as well as some secondary metabolites were estimated. The obtained results revealed that F. creticus contains appreciable levels of nutritive components considering that its nutritional value (351.06 kcal/100g dry wt.) was remarkably higher than that of F. arabica and F. mollis (327.99 and 293.07 kcal/100g dry wt., respectively). The concentration of Na was relatively the highest among the other estimated macroelements in the studied species followed by K, Ca and Mg, respectively while Fe was the highest microelement followed by Cu, Mn and Zn, respectively. The phytochemical composition revealed that methanolic extract of F. creticus was the richest in total alkaloids and flavonoids, while F. arabica found to be the richest in total phenolics and tannins.
