Essential oil composition of 'blue flower rosemary' (Rosmarinus officinalis L.) from subtropical India

摘要

The volatile constituents of aerial parts of the blue flower rosemary (Rosmarinus officinalis L.), grown in foot hills of the Himalayas were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Forty compounds, comprising 96.38% of the oil were identified. The major constituents of the oil were camphor (15.64%), a-pinene (11.66%), 1,8-cineole (9.37%), borneol (8.36%), verbenone (8.23%), linalool (5.11%), limonene (4.34%), exo-bornyl acetate (4.05%), terpinen-4-ol (3.91%), and camphene (3.87%).
