Description
Summary:Essential oil from the rhizomes of Zingiber neesanum (Graham) Ramamoorthy from the Western Ghats region of southern India was isolated and characterized by GC and GC-MS. Oil constituents were identified by comparison of individual mass spectra with databases and the literature, linear retention indices and co-injection. Sixty-one constituents, comprising 97.4% of the oil, were identified. Phenylbutanoids, viz. (E)-1-(3',4'-dimethoxyphenyl)butadiene (31.1%), a potential antiinflammatory compound, and (E)-1-(3',4'-dimethoxyphenyl)but-1-ene (23.1%) were isolated from the oil by prep. TLC, characterized by IR, UV, 1H-NMR and MS and quantified by external standardization. (E)-β-ocimene (12.7%), β-pinene (7.4%) and linalool (4.0%) were the major terpenoid constituents in Z. neesanum rhizome oil. Copyright © 2007 John Wiley & Sons, Ltd.
