测定了14种塞尔维亚药用植物中Fe、Mn、Cu、Zn、Mo、Co、Ni、Se、Sn和Al的含量。研究了以下植物：西洋蓍（西洋蓍），罗勒（Ocimum hasilicum L.），圣约翰草（贯叶连翘L.），胡椒薄荷（Mentha x piperita L.），木贼（问荆（Equisetum arvense L.）），刺荨麻（Urtica dioica L.），百里香（Thumberserpyllum L.），玉米须（Zea mays L.）- 玉米柱头）、木槿（Hibiscus sabdariffa L.）棉花糖（蜀葵（Althaea officinalis L.），洋甘菊（Matricaria chamomilla L.），蔷薇果/狗蔷薇（Rosa canina L.），冬香（Satureja montana L.）和留兰香（Mentha spicata L.）。共检查了16个药用植物不同部位（根、叶、花、草）的样品，其中13个样品以原始包装交付，3个样品为散叶草药。采用微波消解技术制备样品，并采用原子吸收光谱法和电感耦合等离子体质谱法进行测定。所测样品中微量元素的含量范围为：Mn（23.86 - 453.71 mg/kg）; Fe（61.87 - 673.0 mg/kg）; Cu（6.68 - 24.46 mg/kg）;（16.11 - 113.81 mg/kg）;钼（0.576 - 4.265 mg/kg）; Co（0.039 - 0.532 mg/kg）; Se（0.036 - 0.146 mg/kg）; Ni（0.738 - 6.034 mg/kg）; Al（154.0 - 3015.0 mg/kg）和Sn（2.68 - 10.22 mg/kg）。根据测定的微量元素含量，研究的凉茶样品被认为是安全的，供人食用。
Levels of Fe, Mn, Cu, Zn, Mo, Co, Ni, Se, Sn and Al were determined in 14 medicinal plants from Serbia, which are widely used in phytopharmacy as herbal teas. The following plants were investigated: yarrow (Achillea millefolium L.), basil (Ocimum hasilicum L.), St. John's wort (Hypericum perforatum L.), peppermint (Mentha x piperita L.), field horsetail (Equisetum arvense L.), stinging nettle (Urtica dioica L.), thyme (Thymus serpyllum L.), maize silk (Zea mays L. - Maydis stigma), hibiscus (Hibiscus sabdariffa L.), marshmallow (Althaea officinalis L.), chamomile (Matricaria chamomilla L.), rosehip/dog rose (Rosa canina L.), winter savory (Satureja montana L.) and spearmint (Mentha spicata L.). A total of 16 samples of different parts of medicinal plants (root, leaf, flower, herba) were examined, whereby 13 samples were delivered in original package and three samples were loose leaf herbs. Samples were prepared using the microwave digestion technique, and measurements were performed applying the atomic absorption spectrometry and mass spectrometry with inductively coupled plasma. Contents of microelements in the examined samples were in the range: Mn (23.86 - 453.71 mg/kg); Fe (61.87 - 673.0 mg/kg); Cu (6.68 - 24.46 mg/kg); Zn (16.11 - 113.81 mg/kg); Mo (0.576 - 4.265 mg/kg); Co (0.039 - 0.532 mg/kg); Se (0.036 - 0.146 mg/kg); Ni (0.738 - 6.034 mg/kg); Al (154.0 - 3015.0 mg/kg) and Sn (2.68 - 10.22 mg/kg). According to determined amounts of microelements, the investigated samples of herbal teas are considered safe for human consumption.
