Comparison of the Composition of the Essential Oils of Alpinia and Hedychium Species-Essential Oils of Fijian Plants, Part 1

摘要

The essential oils of the leaves, flowers and rhizomes of Alpinia zerumbet (Pers.), A. purpurata (Viell.), Hedhychium coronarium Konig, and H.gardnerianum Lindl. species growing wild in Fiji were obtained by steam distillation and analyzed by GC/MS. The rhizome and leaf oils of A. zerumbet were found to be rich in beta-pinene (4.0%, 10.0%), 1,8-cineole (28.1%, 13.2%) and terpinen-4-ol (41/4%, 40.9%), while the leaf and flower oils of the sampe species contained alpha-pinene (79.6-36.1%) and beta-pinene (29.4-43.0%) and beta-caryophyllene (0-24.2%), respectively. The rhizome and leaf oils of H.coronarium were rich in alpha-pinene (10.6%, 20.9%), beta-pinene (31.4%, 53.6%), 1,8-cineole (55.9%, 11.9%) and beta-caryophyllene (0%, 17.7%), respectively. The rhizome oils of H.gardnerianum were rich in alpha-pinene (10.4-11.0%), beta-pinene (31.0-32.1%), 1,8-cineole (27-29.5%) and linalool (22.6-28.1%). The leaf and flower oils contained alpha-pinene (18.4%, 6.6%), camphene (23.7%, 17.4%), beta-pinene (22.1%, 17.0%), linalool, (13.1%, 4.6%) beta-caryophyllene (7.7%, 17.4%) and caryophyllene oxide (0%, 10.5%), respectively.
