AB  - The stinging nettle (Urtica dioica L.) belongs to the Urticaceae family and represents a perennial plant. Stinging nettle is abundant species occurring in various types of forest, road verges and grassland sites. In many countries is used as both medicine and food. Stinging nettle is a weed and its seeds, leaves and even roots are used for medicinal purpose. Thanks to its high content of nutrients and bioactive compounds like poly phenols, vitamins and minerals, nettle possesses a great nutritional value and a large number of pharmacological effects, including anti-proliferative, anti-inflammatory, antioxidant, analgesic, immunostimulatory, anti-infectious, hypotensive, antiulcer activities and cardiovascular disease prevention. It is a reservoir of minerals (especially iron), vitamin C and pro-vitamin A.
Last decades the popularity of herbal medicine is rapidly increasing all over the world. However, heavy metal toxicity in plant materials has a great impact and importance on herbal plants and consequently affects the quality of herbal raw materials, herbal extracts, the safety and marketability of drugs. This paper presents determination of content seven heavy metals (Cu, Fe, Mn, Ni, Zn, Cd and Pb) in leaves samples Urtica dioica L. collected from five localities in Republic of Serbia. The sample preparation procedure involved dry digestion in triplicate and dissolution of the ash in 6M HCl and then in 0.1 M HNO3. All elements were analyzed using an inductively coupled plasma-optical emission spectrometry (ICP-OES). The contents of Ni, Cu, Zn, Mn and Fe in the leaves were found to be in the ranges of 0.54±0.00 to 1.87±0.10 ˂ 2.12±0.69-12.79±0.53 ˂ 18.18±0.46-28.48±1.37 ˂ 30.63±1.45-68.44±5.11, and 109.75±4.01-244.41±13.50 mg/kg dry weight, respectively. Value of toxic heavy metal Pb in two samples is 0.37±0.0 mg/kg dry weight, whiles content Cd has been below the detection limit. The content of heavy metals in samples were used to calculate target hazard quotients values (THQ) and hazard index (HI).

AB  - Novel composites of BEA zeolite and silver tungstophosphate were prepared by different procedures: two-step impregnation, ion-exchange, and as physical mixtures with varying component mass ratios. Composites were characterized using Atomic force microscopy, Infrared, Raman and Atomic absorption spectroscopy, and results were related to adsorption properties and antimicrobial efficiencies of the composites. Prepared samples were tested as antimicrobial agents for fungal and different bacterial strains, as well as for adsorbents for pesticide nicosulfuron in aqueous solutions by using High-performance liquid chromatography. Experimental conditions for batch adsorption testing were optimized in order to efficiently eliminate nicosulfuron from aqueous solutions, while enabling antimicrobial activity of these advanced materials. Antimicrobial efficiency of composites was verified, and indicated that silver ion persistence in the solid phase is of utmost significance for the antimicrobial activity. Spectroscopic investigation revealed interaction of the silver tungstophosphate active phase and the zeolite framework, giving evidence of uniform distribution of active sites in the synthesized materials that proved to be essential for adsorption application. The best obtained adsorption capacity, as well as highest antimicrobial efficiency, is found for composite samples prepared by two-step impregnation with (BEA: silver tungstophosphate) mass ratio 2:1. The amount of nicosulfuron removed from water suspension was 38.2 mg per gram of composite, and the minimum inhibitory concentration determined for all investigated gram-negative bacteria was 125 μg mL−1.
