BACKGROUND Herbal teas are a good alternative to traditional green, black, red and white teas. Herbal teas infusions are also consumed for therapeutic purposes. Teas are the source of many valuable, biologically active compounds, including elements. Infusions drawn up from various teas may be one of the minerals sources in a daily diet. In the study, an attempt was made to assess infusions prepared from popular teas in terms of the content of elements in them. METHODS In the work, the amounts of elements such as Ca (calcium), Cr (chromium), Cu (copper), Fe (iron), K (potassium), Mg (magnesium), Mn (manganese), Na (sodium), Ni (nickel) and Zn (zinc) were determined in herbal teas infusions as well as yerba mate and rooibos by atomic absorption spectrometry method (AAS). Their participation in covering the daily nutrient requirements for particular elements was also estimated. RESULTS The average amount (mg/g) of elements that passed from 1 g of teas to their infusions was following: Ca - 5.73 ± 3.33, K - 18.14 ± 9.50, Mg - 1.79 ± 3.47, Na - 1.34 ± 0.85, and (μg/g) for: Cr - 0.14 ± 0.14, Cu - 2.56 ± 1.53, Fe - 18.45 ± 11.90, Mn - 64.20 ± 88.82, Ni - 0.49 ± 0.30 and Zn - 10.77 ± 13.89. Among the tested teas, the infusions of hibiscus, horsetail, nettle, rooibos and yerba mate contained the largest quantities of minerals. A significant positive correlation was determined between the pH value of infusion and Mg content, as well as some pairs of correlating elements (Ca-K, Ca-Mg, Cr-Mg, Cu-Zn and K-Mg) were found in the analyzed brews. CONCLUSIONS Generally, the infusions of herbal teas to a small extent cover the daily allowance for elements, however they are a valuable complementary source of them.

根据宏观和微量元素含量评估各种茶浸液的营养价值。

背景技术凉茶是传统的绿茶，黑茶，红茶和白茶的良好替代。凉茶输液也可用于治疗目的。茶是许多有价值的生物活性化合物（包括元素）的来源。从各种茶中提取的浸入液可能是日常饮食中的矿物质来源之一。在这项研究中，人们尝试根据流行茶中元素的含量来评估其浸泡液。方法在工作中，元素的含量包括钙（钙），铬（铬），铜（铜），铁（铁），钾（钾），镁（镁），锰（锰），钠（钠）原子吸收光谱法（AAS）测定了凉茶浸液中的镍（镍）和锌（锌）以及马黛茶和路易波士茶的含量。还估计了它们参与满足特定元素每日营养需求的情况。结果从1克茶到其浸泡液中传递的平均元素含量（mg / g）如下：钙-5.73±3.33，钾-18.14±9.50，镁-1.79±3.47，钠-1.34±0.85，和（微克/克）：Cr-0.14±0.14，Cu-2.56±1.53，Fe-18.45±11.90，Mn-64.20±88.82，Ni-0.49±0.30和Zn-10.77±13.89。在经过测试的茶中，木槿，马尾，荨麻，如意宝和yerba mate的浸入物中含有最多的矿物质。测定的pH值与镁含量之间存在显着的正相关，分析中发现了几对相关元素（Ca-K，Ca-Mg，Cr-Mg，Cu-Zn和K-Mg）。酿造。结论一般来说，
