Constituents of the essential oils ofCinnamomum sintoc Blume from a mountain forest of Peninsular Malaysia

Abstract

The leaf, twig, bark and wood oils of Cinnamomum sintoc Blume from a mountain forest of peninsular Malaysia were analysed by GC and GC-MS. Safrole (23.4%) and γ γ γ γ γ-muurolene (13.5%) were the major components of the leaf oil. Other compounds present in appreciable amounts in the oil were eugenol, linalool, terpinen-4-ol, α α α α α-cadinol, germacrene D, α α α α α-terpineol and δ δ δ δ δ-cadinene. The most abundant component of the bark oil was linalool (23.8%). Sesquiterpenes accounted for 25.2% of the oil with α α α α α-copaene, allo-aromadendrene, γ γ γ γ γ-muurolene and cubenol present in appreciable amounts. The bark oil was also rich in aldehydes where tetradecanal (16.4%) was the major representative. The wood oil was similar to the bark oil in the content of aldehydes but the concentration of each component was different. The oil also contained appreciable amount of acids (27.9%), represented by octadecanoic acid, pentadecanoic acid, hexadecanoic acid and tetradecanoic acid. The twig oil could be a natural source of linalool as it constituted 52.9% of the oil. Other major components of the oil were methyl (Z)-cinnamate and its E-isomer, which were both present at 6.0% concentration. The chemical composition of the oils in the present study was markedly different from those previously reported on C. sintoc collected from two different locations, suggesting the existence of intraspecific chemical races within the species.

CHEMICAL COMPOSITION OF ESSENTIAL OILS AND ITS LOCOMOTOR ACTIVIT FROM THE BARKS OF Cinnamomum sintok Bl OF TWO DISTRICTS IN MIDDLE JAVA

“…The composition of barks sintok oil in this study were significantly different from those reported by Jantan et al [6], which indicated that the linalool was dominant in barks oil (23.8%), followed tetradecanal (16%). Surprisingly, eugenol and their derivatives did not found in bark of sintok Pahang, Malaysia.…”

“…terpinen-4-ol (2.4%) and p-cymene (1.3%), the other monoterpenes were present in <1% concentration in the oil [6].…”

“…Jantan et al examined chemical contents in sintoc bark form Malayan peninsula using gas chromatography and mass spectroscopy [6]. They found that sintoc barks consist of safrole (23.4%), murolen (13.5%), along with adequate amounts of eugenol, linalool, germakren, kadinen, terpinol, and the other terpenes.…”

Essential Oils in Mexican Bays (Litsea spp., Lauraceae): Taxonomic Assortment and Ethnobotanical Implications1

“…These compounds are also common to other Lauraceae species, including Cinnamomum, Laurus, Lindera, Ocotea, and Persea genera (Jantan et al 2005;Nor Azah and Jantan 1999;Palazzo et al 2009;Setzer et al 2007). The essential oil of Laurus nobilis leaves contains the nine compounds mentioned before (Kovacevic et al 2007); Laurus azorica has eight of them, lacking caryophyllene oxide (Pedro et al 2001), and Lindera benzoin has seven, lacking linalool and 1,8-cineole (Tucker et al 1994).…”
