Analyses of the Headspace Volatile Constituents of Aerial Parts (leaves and stems), Flowers and Fruits of Bidens gardneri Bak. and Bidens sulphurea (Cav.) Sch.Bip. Using Solid-Phase Microextraction

The present study describes the volatile composition of aerial parts (leaves and stems), flowers and fruits from Bidens gardneri and Bidens sulphurea. The first species is widely distributed in Pantanal (Brazil) and is a traditional medicinal plant, while the second species is widely distributed throughout Brazil. In all analyses, observed were constituents like bicycloelemene, alpha-copaene, beta-caryophyllene, germacrene D, bicyclogermacrene and others. However, some compounds were identified only in one part of the plants analyzed. These results indicated sonic differences in the composition of the plants studied and they were in agreement with data of literature.
