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  - Chemical components of teas have received great interest because they are related to health. In this work, data on the determination of foreign matter, loss on drying/water content, total ash and ash insoluble in hydrochloric acid are presented. The content of seven heavy metals including Cu, Fe, Mn, Zn, Ni, Cd and Pb were determined by atomic absorption spectrometry in samples of several herbal teas: Matricariae flos, Thymi herba, Menthae piperitae folium, Betulae folium, Quercus cortex, Gentianae radix, Frangulae cortex, Althaeae radix, Uvae ursi folium and Glycyrrhizae radix collected from Šabac’s market, Serbia. The sample preparation procedure involved dry digestion and dissolution of the ash in 6M HCl and then in 0.1 M HNO3. Herbal teas showed the concentration of heavy metals Cu, Fe, Mn, Zn and Ni in the range: 2.9 ± 0.1 – 22.2 ± 0.9 mg/kg, 118.5 ± 1.1 – 755.5 ± 2.5 mg/kg, 19.0 ± 5.8 – 561.0 ± 1.9 mg/kg, 6.5 ± 0.4 – 242.5 ± 1.4 mg/kg and 2.5 ± 0.1 – 10 ± 1.1 mg/kg, respectively. The level of copper in all samples was uniform. The highest content of Fe was in Thymi herba, while Mn and Zn were at maximum in Betulae folium. The levels of toxic heavy metals Cd and Pb were below the detection limit. The obtained values were compared with data available from literature. The herbal tea samples analyzed contained essential heavy metals (Cu, Fe, Mn, Zn) and probably essential in trace (Ni), and could obey the daily dietary requirements. Noncancer health risk assessment detected that the herbal teas of Betulae folium and Frangulae cortex can manifest some health risk to consumers.
