Tradescantia pallida is a herbaceous plant with promising compounds in its composition that can be applied in several areas such as agronomic, pharmaceutical and chemical. However, further studies on this plant are needed in order to characterise it phytochemically, pharmacologically and toxicologically. In this sense, the present study aimed to verify the unprecedented identification of its essential oil (EO) components. The EO extraction of T. pallida aerial parts was performed by hydrodistillation in a Clevenger apparatus (5 h), and the chemical analysis by gas chromatography coupled to mass spectrometry. The oxygenated sesquiterpene was the dominant class in EO composition and spathulenol (19.56%) was the principal identified compound, followed by caryophyllene oxide (18.84%), β-caryophyllene (13.65%) and α-copaene (6.08%). The chemical identification of sesquiterpene compounds (oxygenated and hydrocarbons) in EO contributes to the understanding of the biological activities evidenced by T. pallida reported by literature.
