Abstract

High temperature high resolution gas chromatography coupled to mass spectrometry (HT-HRGC-MS) isa powerful analytical tool. In this work we applied this technique to the study of crude extracts of propolis collected near the city of Uberlândia-Minas Gerais State. Eucalyptus trees and native plants from "cerrado" (savannah) were the material sources disposable for the Apis mellifera bees. A lot of known propolis constituents were identified, however, several high molecular weight compounds including lupeol alkanoates were identified for first time in propolis.
