Žabčíková, Hana
The diploma thesis deals with the issue of herbal tea, which is registered as medicinal product. The consumer market research has shown that these kinds of tea are put on the market by Megafyt Pharma s.r.o. and Leros s.r.o. An overview of all single-species medicinal tea and tea mixtures from both producers was created. In the practical part, the content of essential oil in the medicinal tea leaves of chamomile and sage from the producer Megafyt Pharma s.r.o. and the content of tannins in the tea leaves of Agrimonia eupatoria from the same producer were determined. The samples of individual drugs of different ranks were used for the determination and the evaluation was performed according to the Český lékopis 2017. The results were statistically evaluated. The obtained results showed that the essential oil content of chamomile corresponds to the pharmaceutical quality, but for the sage sample the essential oil content does not correspond to the given standard. In the case of Agrimonia eupatoria, the content of tannins was lower than determined by the Český lékopis 2017, only one sample of the given rank showed a higher content. Furthermore, the frequency of occurrence of individual species of herbs contained in the registered tea mixtures was evaluated.
