Chemical Composition of the Essential Oil from the Leaves of Curcuma zedoaria Rose,of Indian Origin

摘要

The essential oil,which was produced by hydrodistillation of Curcuma zedoaria(Zingiberaceae)leaves,was investigated by GC and GC/MS.Twenty-three compounds were identified,accounting for 75%of the oil.The oil of C.zedoaria was made up mainly of mono-and sesquiterpenoids,monoterpene hydrocarbons(2.3%),oxygenated monoterpenes(26%),sesquiterpene hydrocarbons(38%),and oxygenated sesquiterpenes(13.5%).alpha-Terpinyl acetate(8.4%),isoborneol(7%),dehydrocurdione(9%)and selinalpha-4(15),7(11)-dien-8-one(9.4%)were the major constituents of the leaf oil.
