Chemical profile, antiproliferative and antioxidant activities of rhizome oil of Zingiber anamalayanum from Western Ghats in India

Abstract

Volatile oil from fresh rhizomes of Zingiber anamalayanum was isolated by hydrodistillation and characterised by GC-FID and GC-MS. Twenty-one out of 24 constituents comprising 99.47% of the oil were identified. Major components in Z. anamalayanum rhizome oil were δ-2-carene (52.83%), camphene (9.83%), endo-fenchol (9.42%), iso-dihydrocarveol (6.44%) and cis-p-mentha-2,8-dien-1-ol (5.19%). Monoterpene hydrocarbons in the rhizome oil were 65.81%, followed by oxygenated monoterpenes (23.78%) and sesquiterpene hydrocarbons (9.87%). Physical parameters of rhizome oil were [Formula: see text] 1.4031, [Formula: see text] - 16.097(o) (c = 1, CHCl3) and [Formula: see text] 0.9202. Z. anamalayanum rhizome oil showed significant anti-Dalton's Lymphoma Ascitic activity.
