abstract The essential oil of lavender flowering parts and stems was analyzed by capillary GC and GC/MS. Sixty-six constituents were identified, which constituted 92.1% of the total integrated area of the detected GC peaks. The concentration of the linalool in the flowering parts was 5372.4 mg/kg, that of linalyl acetate 5121.7 mg/kg, that constituted 22.0% and 26.5% respectively in the total oil. The oil content in the stems was more than 30 times lower than in the flowering parts.
