High-temperature high-resolution gas chromatography (HT-HRGC) and HT-HRGC coupled to mass spectrometry (HT-HRGC-MS) were applied to the study of propolis collected by Apis mellifera and by Tetragonisca angustula, a stingless bee native to southeastern Brazil. With the exception of amino acids and erytrose/erythritol content, both propolis samples were quite similar in composition and in antimicrobial activity. Triterpenes were the most abundant compounds in the samples, comprising more then 35% of the total amount of each sample.
Key words: propolis / Apis mellifera / Tetragonisca angustula
