Analysis of Volatile Organic Compounds from the Aerial Parts of Medicinal Plant, Galium verum

The Galium verum herb, (Rubiaceae family) is well represented in the spontaneous Romanian flora. She is one of the most used plants in traditional medicine. Our research aimed to investigate the chemical volatile profile in fresh, dried and essential oil of Gallium verum using SPME and hydrodistillation techniques, followed by GC-MS analysis. Characterization of volatile compounds composition by SPME GC-MS technique presented din this paper is the first study on fresh and dried of Galium verum plant to our knowledge. Galium verum fresh flower floral bouquet is given by monoterpenes (73,5%), sesquiterpenes (10,16%), esters (10,26%) and others(5.87%). The floral bouquet of Gallium verum dried flower, contains mainly: aldehydes (35.48%) monoterpenes (35.48%), alcohols (11.96%), sesquiterpenes, (3.71%), esters (3.14%) and others (10.11%). Sixty components were identified in the galium essential oil.
