“…The presence of valuable biologically important compounds such as proteins, vitamins, phenolic components, macro and microelements, tannins, fl avonoids, sterols, fatty acids, carotenoids and chlorophylls [GuilGuerrero, Rebolloso-Fuentes, & Torija-Isasa, 2003] [Nica, et al, 2012] [ Vega-Maray, Fernández-González, & Valencia-Barrera, 2006] [Grevsen, & Fretté, 2008] [Pinelli, Ieri, & Vignolini, 2008] [ Kopyt'ko, Lapinskaya, & Sokol'skaya, 2012] [Kukrić, et al, 2012], contributes to the utilization of stinging nettle in different ways. The high nutritive values caused stinging nettle leaves to be included in the human consumption, as a tonic for strengthening the body, in the preparation of soups and various dishes and as a natural source of food fl avouring [Wetherilt, 2003] [Council of Europe, 2008].…”

Content of proteins and minerals (Mg, Ca, Cu, Zn, Mn and Co) in leaves, stem and root of stinging nettle collected from different localities from the Republic of Macedonia were determined. Generally, the higher content of proteins and minerals were determined in leaves, followed by the content in stem and root. In the quantity of proteins significant differences were determined depending to the organ of stinging nettle. The highest determined values for the protein content in leaves expressed to the dry mass were 26.89% in leaves, 14.54% in stem and 10.89% in root. The values for the calcium content in stinging nettle were higher in comparison to the magnesium values. Zink content in the leaves was two and fi ve times higher than the content of copper and manganese, respectively. In leaves, stem and root non signifi cant differences in cobalt content were determined.

“…The whole plant is used as a diuretic, antihypertensive, anti-diabetic, hemostatic, anti-asthenia, antianemic, antispasmodic, antirheumatic, and as a remedy for headaches and chills (Belščak-Cvitanović et al, 2015). The presence of precious biologically important composites such as proteins, vitamins, phenolic factors, macro-and microelements, tannins, flavonoids, sterols, adipose acids, carotenoids, and chlorophylls contributes to the application of stinging nettle in different ways (Nica et al, 2012;Kopyt'ko et al, 2012). Therefore, nettle is used as a dietary supplement as well as for the production of functional foods.…”

Stinging nettle (Urtica dioica) is an edible plant, well-known for its nutraceutical properties. Stinging nettle leaves are typically rich in fibers, minerals and vitamins, as well study was to evaluate the sensory properties and the rheological properties of wheat salted biscuits after adding of dried nettle leaves to flour wheat at different concentrations of 5,10 and 15 % antioxidant compounds, i.e., phenols and flavonoid. along with the control sample. Also, changes in the microbial load of biscuits added to nettle leaves during storage periods (1,3,6 and zero time) were investigated. Showed that total bacterial counts were not detected at all directly after processing with all used concentration increased gradually with time. At 5%, and 10% concentration, total bacterial count appeared a month later zero time. During storage period, total bacterial count appeared and a month later with (3.08 and 2.30 log cfu/g) and increased gradually to reach (3.34 and 2.77 log cfu/g) respectively, while 6 months later of storage, total bacterial counts increased gradually reaching (5.50, 4.91 and 4.56 log cfu/g) with concentrations 5%,10% and 15% respectively compared to control. It means that, 15% can be enough as preservation treatment for biscuits. concentration with 15% had higher effect, where total bacterial counts appeared after 3 months (2.30 log cfu/g) and increased to (4.65 log cfu/g) after 6 months of storage. fungi was not detected (ND) through increasing time of storage due to the low moisture in biscuits samples and reducing the numbers of fungies in the various concentrations of nettle leaf. The antimicrobial activity of ethanolic and methanolic extracts of nettle they demonstrated no effects against yeast-like fungi (Candida albicans). Although all extracts exhibited an antimicrobial activity against all tested bacteria with inhibition zones ranging from 10.0±0.58 to 12.7±0.67 mm., they were more effective against gram-positive bacteria (Bacillus cereus and Staphylococcus aureus) than against gram gram-negative bacteria (Salmonella typhimurium and Escherichia coli).

This research is for academic understanding to work out new ligand behavior4-({(5-(4-hydroxyphenyl)-3-sulfanyl-1H-1,2,4-triazol-1-yl)amino}(1H-tetrazol-5-yl)methyl)-2-methoxyphenol (L) with gold (III) and nickel (II) metal ions. Ligand (L) has been synthesized from cyclization of the interaction of (4-hydroxy-3-methoxyphenyl){[5-(4-hydroxyphenyl)-3-sulfanyl-1H-1,2,4-triazol-1-yl]amino}acetonitrile (F) with sodium azide. α-Amino nitrile compound (F) intern synthesized from interaction of aldehyde amine and KCN acidic medium as three components one put reaction. The presence of well oriented donor atoms (N2-type) of ligand (L) interacted with gold (III) and nickel (II) ions under reflux to prepare [1:2] [M:L]Cl electrolytic complexes, the complexes [Au (L)3]Cl3and [Ni (L)2]Cl2were suggested to have square planar geometry. The resulting products were characterized via technical1H-NMR, UV-Vis, IR spectroscopy, conductivity and EDX. The cytotoxic effect was studied on a breast cancer cell line (MCF-7 cell line). At different concentrations for both complexes. The results showed that gold(III) complex has higher cytotoxicity than nickel(II) complex against cancer cell line.
