[email protected] Abstract: Numerous volatile organic compounds (VOCs) with a large chemical diversity are emitted by plant flowers. They play an important role in the ecology of plants, such as pollination, defense, adaptation to their environment, and communication with other organisms. The Tillandsia genus belongs to the Bromeliaceae family, and most of them are epiphytes. The aromatic profile of the Tillandsia genus is scarcely described. In this study, we use the headspace solid phase microextraction (HS-SPME) coupled with gas chromatography combined with mass spectrometry (GC-MS) method developed in our laboratory to explore the chemical diversity of the VOCs of fragrant flowers Citation: Lo, M.-M.; Benfodda, Z.; of three species of the genus Tillandsia. We were able to identify, for the first time, 66 volatile Bénimélis, D.; Fontaine, J.-X.; Molinié, compounds (monoterpenes, sesquiterpenes, phenylpropanoids, and other compounds). We identified R.; Meffre, P. Extraction and 30 compounds in T.
