With regard to the vibrational spectrum, the band at 1693 cm-1, ascribed to ¿(CO) terpenic oxo groups, suggests the presence of diterpenes, while the existence of hydroxystilbenes and their glycosides is consistent with the absorption bands in the 3380-3080 cm-1, 1800-1300 cm-1 and 1000-450 cm-1 regions. On the other hand, the thermal behavior of the Siberian chewing gum, elucidated by thermogravimetry (TG), derivative thermogravimetric (DTG), differential thermal analysis (DTA) and differential scanning calorimetry (DSC) techniques, resembles that of arabinogalactan, albeit with a more delayed decomposition. info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Martín-Gil, Jesús Fernández-Coppel, Ignacio A.
