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 alpha-pinene (0.2-3.2%), myrcene (0.3-4.1%), (E)-beta-ocimene (0.2-9.6%), bicycloelemene (0.2-18.0%), beta-elemene (0.3-4.9%), beta-caryophyllene (0.1-17.8%), germacrene D (4.4-20.1%), bicyclogermacrene (4.2-27.9%) and delta-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, delta-3-carene (8.2%), alpha-amorphene (6.5%), beta-phellandrene (5.5%) and beta-pinene (5.1%) were identified in P. jucunda leaf, while sabinene (30.9%) and beta-phellandrene (10.2%) occurred largely in the stem. Moreover, gamma-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 alpha-terpinene (7.8%) and beta-gurjunene (5.2%) were identified only in the leaf oil.
