Propolis produced by a stingless bee (Geniotrigona spp.), commonly known as "Kelulut" in Malaysia, is known to possess various medicinal values. It is a resinous product that is used to build the beehives. Chemical constituents of propolis differ and depend on many factors such as regions and species. To date, the study of the chemical constituents of Geniotrigona thoracica propolis from Malaysia is still lacking. Hence, this study report the chemical constituents from Malaysian G. thoracica propolis collected from Kota Bharu, Kelantan, Malaysia. The ethanolic extract of propolis (EEP) was derivatized and analyzed by gas chromatography–mass spectrometry (GCMS). The compounds were later identified by library searching Wiley 275 and NIST 02 mass spectral databases. Out of the 48 individual compounds identified, 30 compounds were identified for the first time from propolis. The main class group compounds were phenolic compounds and terpenoids. 1H-Pyrrole-2-carboxylic acid, 1-(2-hydroxy-2-phenylethyl) and fren-9(11)-en-2.alpha.-ol were the main identified phenolic compound and terpenoid, respectively.
