The hydro-distilled essential oil obtained from the flowering aerial parts of Lepidagathis fasciculata Nees was analyzed by gas chromatography equipped with a flame ionization detector (GC-FID) and gas chromatography coupled with mass spectrometry (GC/MS). A total of 38 compounds have been identified, representing 91.2% of the total oil. The major constituents were δ-cadinene (14.4 %), γ-curcumene (9.8%), sandaracopimarinal (6.6%), germacrene D-4-ol (6.1%), cembrene (5.0%), β-calacorene (3.6%), ar-curcumene (3.3%), trans–4,10-epoxy-amorphane (3.2%), abietatriene (2.9%), and α-cubebene (2.8%). The oil was rich in sesquiterpene hydrocarbons (43.8%).
