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

Abstract

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.

Cromathographic Profile of Volatiles of Multifloral and Unifloral Honey Collected by Apis Mellifera from Transilvania, Romania

“…According to the studies of melisopalinological analysis made by authors from Romania, it was found that Apis mellifera honey bees from Romania collects pollen mainly from Brassica napus, Tilia, Heliantus and Robinia pseudocacia [13]. In other paper [14] we identified by SPME/GC-MS, the volatiles from melliferous plants: acacia, rape, linden and sun flower. This was the reason we have studied honey produced from these plants.…”
