Erythrina variegata L. is a tree up to 20 meters tall that has been used for timber as well as medicine. Traditional Vietnamese medicine has used the bark of this plant to disinfect, treat itchy skin, treat rheumatism and numb. Elucidation of essential oil components in the bark may contribute to the explanation of biological activities. In this work, the essential oils from young branches and stem bark of E. variegata were obtained by hydrodistillation and analyzed by gas chromatography – mass spectrometry (GC-MS). The essential oils were dominated by sesquiterpenoids, including α-copaene (6.3% and 4.6%), β-copaene (9.4% and 7.0%), γ-muurolene (7.5% and 6.7%), α-muurolene (6.2% and 4.4%), γ-cadinene (6.3% and 5.9%), and δ-cadinene (6.7% and 5.6%). Although the essential oils were rich in sesquiterpenoids, the yields were low (0.045 and 0.052%).
