Abstract :
Essential oil obtained by hydro-distillation from fresh leave of Alpinia nigra was analyzed by Gas Chromatography Mass Spectrometry (GC-MS). Fifty three compounds were identified in the leaf oil. The main essential oil compositions were 1,5,9,9-Tetramethyl-1,4,7-cycloundecatriene (24.92%), 6,6-Dimethyl-2-methylenebicyclo[3.1.1]heptanes (12.90%), 5-Amino-6-(2 fluoroanilino)furazano[3,4-b]pyrazine (12.18%), 4,11,11-Trimethyl-8-ethylenebicyclo[7.2.0]undec-4-ene (10.76%), 6-(3-Fluorobenzyl)-1,2,3,4,5,6-hexamethyl-2,4-cyclohexadien-1-ol (5.77%), 1,6,10-Dodecatrien-3-ol, 3,7,11-trimethyl-, (E)- (5.41%), Caryophyllene oxide (2.61%), 5,5-Dimethyl-4-[(1E)-3-methyl-1,3-butadienyl]-1-oxaspiro[2.5]octane (2.44%), 1,5,5,8-Tetramethyl-12-oxabicyclo[9.1.0]dodeca-3,7-diene (1.96%), Sabinen (1.79%), D-Limonene (1.39%), α-Cadinol(1.20%).
