Essential oil constituents of leaves of three Myristica species namely, Myristica beddomeii, M. fragransand M. malabarica were determined by gas chromatography and gas chromatography-massspectrometry. M. fragrans was dominated by monoterpenes (91%), M.  beddomeii contained mono-(48%) and sesquiterpenes(35%) whereas M. malabarica was dominated by sesquiterpenes (73%).The leaf oil of M.  beddomeii was dominated by α-pinene (19.59%), t-caryophyllene (14.63%) andβ-pinene (12.46%).  The leaf oil of M. fragrans contained sabinene (19.07%), α-pinene (18.04%), 4-terpineol (11.83%), limonene (8.32%) and  β-pinene (7.92%) as major compounds, while t-caryophyllene (20.15%), α-humulene (10.17%), nerolidol (9.25%) and  δ-cadinene (6.72%) werepredominant in the oil of M. malabarica. Linalool, α-terpineol, t-caryophyllene, β-elemene and γ-elemene were present in all the three species. This is the first report on the essential oil compositionof M. beddomeii leaves.
