The essential oil extracted from the leaves of Premna serratifolia underwent hydrodistillation using a Clevenger-type apparatus and was subsequently subjected to analysis through gas chromatography coupled with mass spectrometry (GC/MS). The predominant compounds in the essential oil were those with sesquiterpene skeletons, in both hydrocarbon and oxygenated forms. Notable constituents included caryophyllene oxide, accounting for 23.4% of the oil, (E)-βcaryophyllene at 15.5%, as well as phytol (6.9%), α-copaene (5.5%), and δ-cadinene (4.4%).
