Herbal teas are a popular beverage, that can be prepared very easily (by pouring hot water on various dried herbs). It is very important to monitor and develop a screening methodology for detecting the metal content of both tea plants and herbal tea. A variety of bioactive phytochemicals in the human diet are from f plant-based foodstuffs. Due to their minor side effects, the medicinal plants are widely used to treat many human diseases. Polyphenols, the most abundant components in tea, determine the quality and health function of tea. There are a variety of methods for the analysis of total polyphenols content from tea and medicinal plants, which range from the traditional titration method, to the widely used spectrophotometry based on the color Folin-Ciocalteu reaction. Natural products from medicinal plants, from the old foundations of traditional medicine, play today a vital role in the discovery of new active therapeutic agents. The aim of this study was to establish the total content of polyphenols of herbal of tea (medicinal plant) grown in different regions of Romania. In our work we collected herbal teas from county Gorj. These herbals are rosehip (Rose canina), chamomile (Matricaria chamomilla), peppermint (Mentha piperita), marigold (Calendula officinalis), yarrow (Achillea millefolium), and perforate St John's-wort (Hypericum perforatum). The content of total phenols from medicinal plants were estimated by the Folin Ciocalteu method, a spectrophotometric method. The content of phenols in medicinal herbs shows significant variations determined by the nature and type of herbal tea. [ABSTRACT FROM AUTHOR] |
