Abstract:
:This study is designed to examine the chemical composition of the essential oil obtained from Buddleja thyrsoides Lam leaves from south Brazil. Gas chromatography/mass spectrometry analysis resulted in the detection of 12 components, representing 91.4% of the total oil composition. Germacrene D (27.16%), 1,10-di-epi-Cubenol (13.37%), α-Cadinol (12.95%), Bicyclogermacrene (9.00%), Globulol (8.59%) and caryophylene E (5.26%) were the main components. To the best of our knowledge, this is the first study of the composition of essential oil of the B. thyrsoides collected in Brazil.
