In this study, a solid phase micro extraction (SPME) method with gas chromatography-mass spectrometry (GC-MS) was used for analysis of volatile compounds in flowers and bulbs of three Ornithogalum species. The samples of flowers and bulbs of Ornithogalum sigmoideum, Ornithogalum orthophyllum, Ornithogalum oligophyllum was separately analyzed by SPME-GC-MS. A comparison of volatile compounds was made between species and the parts studied. A total of 70 compounds were identified and different volatile compounds were determined in distinct parts of the species. The major volatile organic compound of the flowers of O. sigmoideum and O. ornithogalum was furan (54.5% and 57.0% respectively). For O. oligophyllum the major volatile organic compound was nonanal (19.2%). Analyses revealed that SPME-GC-MS method is appropriate for the analysis of volatile compounds of Ornithogalum species.
