This article reports the chemical components identified in the essential oil from the leaf and stem barks of Polyalthia harmandii (Pierre) Fin. and Gagnep., Polyalthia jucunda (Pierre) Fin. and Gagnep. and Polyalthia thorelii (Pierre) Fin. and Gagnep. The compounds identified in all the samples were α-pinene (0.2-3.2%), myrcene (0.3-4.1%), (E)-β-ocimene (0.2-9.6%), bicycloelemene (0.2-18.0%), β-elemene (0.3-4.9%), β-caryophyllene (0.1-17.8%), germacrene D (4.4-20.1%), bicyclogermacrene (4.2-27.9%) and δ-cadinene (0.2-4.5%). Besides, benzyl benzoate (9.7%) and ishwarane (8.0%), respectively, were the other prominent compounds in the leaf and stem of P. harmandii. In addition, δ-3-carene (8.2%), α-amorphene (6.5%), β-phellandrene (5.5%) and β-pinene (5.1%) were identified in P. jucunda leaf, while sabinene (30.9%) and β-phellandrene (10.2%) occurred largely in the stem. Moreover, γ-elemene (22.3% and 12.3%), germacrene D (10.5% and 6.9%) and spathulenol (9.1% and 11.8%) were identified in the leaf and stem of P. thorelii, while α-terpinene (7.8%) and β-gurjunene (5.2%) were identified only in the leaf oil.
