J. S. Jangwan, Naveen Kumar and Raghubir Singh

The chemical composition of the essential oils of Skimmia lauriola growing in Northern Garhwal, Himalaya has been studied. The wildly growing plants were collected from Dhanolti region of Tehri Garhwal. Essential oil was extracted by hydrodistillation methods and analyzed by GC/MS. Thirty seven components were identified, which constitutes 86.33% of the total oil. The major constituents are linalool acetate (26.40 %), L-linalool (14.18 %), β-phellendrene (9.03 %), prejeijerene (7.06 %), α-terpineol (6.25 %), geranyl acetate (3.89 %) and myrcene (2.18 %). The essential oil was evaluated for antibacterial activity. The activity was more pronounced against Pseudomonas aurens with 8 mm zone of inhibition followed by Escherichia coli with 5 mm inhibition while Bacillus subtilis and Staphylococcus aureginosa were totally unaffected.
