Volatile constituents of essential oils isolated from different parts of Alpinia calcarata Rosc

The essential oils isolated from different parts of Alpinia calcarata Rosc., (family: Zingiberaceae) growing in Hyderabad, south India, were analyzed by capillary GC and GC/MS. The oil yields were: flower 0.06%, leaf sheath 0.03%, stem 0.05% and root 0.18%. Sixty-two compounds accounting for 92.3-98...

Description
Summary:The essential oils isolated from different parts of Alpinia calcarata Rosc., (family: Zingiberaceae) growing in Hyderabad, south India, were analyzed by capillary GC and GC/MS. The oil yields were: flower 0.06%, leaf sheath 0.03%, stem 0.05% and root 0.18%. Sixty-two compounds accounting for 92.3-98.3% of the oils were identified. The flower oil contained beta-pinene (12.5%), 1,8-cineole (12.8%) and (E)-methyl cinnamate (12.3%) as the major constituents. The important components of the leaf sheath oil were 1,8-cineole (23.2%) and humulene epoxide I (10.6%). The stem oil had beta-pinene (11.2%) and 1,8-cineole (33.2%) as the major compounds. On the other hand, the root oil showed camphene (13.6%), 1,8-cineole (15.6%) and alpha-fenchyl acetate (37.6%) as the main constituents.
