| Popis: |
A simple procedure, previously set up for the quick evaluation of aromatising herbs by direct headspace gas chromatographic analysis, was checked with regard to its application as a routine method. Many samples of herbs and drugs of various kinds and of different qualities were subjected to a sensory evaluation and to headspace analysis. There are significant analytical differences between herbs of good and inferior quality in agreement with the organoleptic evaluation of the same drugs, judged by an experienced panel of tasters. Some tests were performed to determine the exact content of each substance present in the headspace of the examined herbs: preliminary results are given. A suitable internal standard was used for quantitative purposes. The proposed technique is in accordance with the requirements of the Quality Control Service. |
