摘要

Within the continual control of the quality of herbal teas and spices from the market in recent years, unusual foreign matters have sometimes been observed upon macroscopic investigation of some samples of tea-bags containing Matricaria flower or Peppermint leaf. Therefore a spot check of these herbal teas in Austria has recently been performed on tea-bags and crude drug sold in supermarkets, health food stores, tea specialist shops, chemist's shops and pharmacies according to the Codex Alimentarius Austriacus and the European Pharmacopoeia. The results of the analysed samples of Matricaria flower and Peppermint leaf showed that the essential oil content, in particular, could be regarded as a criterion for quality. High amounts of stems, foreign organs or foreign matter indirectly influenced the content on essential oil. The limits for total ash and ash insoluble in HCI were exceeded by very few samples.
