Studies on the Chemical Profile of Some Melliferous Plant from Cluj Area, Romania, Using Different Extraction Techniques

In this paper chemical compounds collected from melliferous plants (Cluj, Transylvania-area flora) using two methods and identified by GC-MS were presented. The melliferous plant studied : acacia, rape, linden and sun flower, represent a rich source of nectar and pollen used in the honey production. The methods were SPME (solid phase microextraction) coupled with GC-MS (gas chromatography and mass spectrometry) and alcoholic extraction of flowers followed by GC-MS. It was pursued in special the identifying of components with semiochimical role. They were identified a total of 158 compounds, from which some semiochemical compounds were already known, but also new compounds were discovered.
