Identifier 10 Introduction The genus Myristica (Myristicaceae), comprising of 72 species, is distributed from India and South East Asia to North Australia and the Pacific Islands. M. fragrans (Houtt.) is the commercially important species, which yields two distinct spice products, nutmeg and mace. The volatile oils of nutmeg and mace have been widely studied (Lawrence 1997, 2000, 2005; Mallavarapu & Ramesh 1998). The major constituents of oils of both nutmeg and mace are monoterpene hydrocarbons, together with smaller amounts of oxygenated monoterpenes and aromatic ethers (Purseglove et al. 1981). Among monoterpene hydrocarbons, pinene and sabinene dominate in the oil and the major aromatic ether constituent is myristicin. The aromatic ethers, myristicin, safrole and elemicin determine the flavour and medicinal properties of nutmeg to a great extent. M. beddomeii (King) and M. malabarica (Lamk.) are two species occurring in the evergreen forests of Western Ghats in India. The nut and mace of M. malabarica are known as Bombay nutmeg and Bombay mace respectively, and are used to adulterate M. fragrans products (Gamble 1967; Hooker 1973). Phytochemical studies have revealed the occurrence of several terpenes, flavones and diarylnonaoids in M. malabarica (Purushothaman et al. 1997; Talukdar et al. 2000; Sabulal et al. 2007). There is no report on the chemistry of M. beddomeii, till date. This prompted us to investigate the essential oil composition of M. beddomeii leaf which is Chemical composition of leaf oils of Myristica beddomeii (King), Myristica fragrans (Houtt.) and Myristica malabarica (Lamk.)

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%) and β-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 tcaryophyllene (20.15%), α-humulene (10.17%), nerolidol (9.25%) and δ-cadinene (6.72%) were predominant 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 composition of M. beddomeii leaves.

Description Essential oil constituents of leaves of three Myristica species namely, Myristica beddomeii, M. fragrans and M. malabarica were determined by gas chromatography and gas chromatography-mass spectrometry. 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%), -caryophyllene (14.63%) and β-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 tcaryophyllene (20.15%), α-humulene (10.17%), nerolidol (9.25%) and δ-cadinene (6.72%) were predominant in the oil of M. malabarica.
