Obviously, the preparation methods produced substantially different scent aromagrams recorded with GC-MS. Each procedure showed individual characters. The two distillation methods were proved to be the most effective ones considering both the number and the sum of the peak intensities expressed in the undecanol-1 internal standard (ISTD). Extracted and identified compounds were methyl esters of open chain acids, terpenes, sesquiterpenes, carotenoid derivatives and the benzene relative components were the most intense. Among the SPME fibres, PDMS-DVB showed the highest general sensitivity in the chemical classes. Among the fruity and sweet nuance bearing “lacton” and “furans” in the high smell activity categories Carboxen-PDMS seems acceptably good. The PDMS fibre is not really proper for red paprika scent analysis and Polyacrylate practically can not be used at all. Comparison of the SPME and distillation results permits to recognize and circumscribe what artefacts, if any,were induced by the distillation steps of the sample preparation procedure.}, year = {2014}, pages = {465-465} } @{MTMT:2744584, title = {Investigation of nicotine contents of chamomile samples by HPLC/TOF-MS method}, url = {https://m2.mtmt.hu/api/publication/2744584}, author = {Lelik, László and Komáromi, Bonifác and Marta, Nadosi and Katalin, Nemes}, booktitle = {Abstract Book 20th International Mass Spectrometry Conference}, unique-id = {2744584}, abstract = {Three different reasons may lead to nicotine content in plants: ibiosynthetic processes in the plants, iipesticide residues, iiithe treatment of the plants.

The nicotine contents of chamomile samples are 1-3 mg/kg. It is several times higher than the limit value.
