Chemical Composition and Antibacterial Activity of Volatile Oil of Sequoia sempervirens (Lamb.) Grown in Egypt

Antibacterial activity of Volatile oil of Sequoia Sempervines Hydrodistilled leaves of Sequoia sempervirens has showed a dose-dependent antioxidant activity by using diphenyl solution. The antimicrobialactivity of S. sempervirens leaves oil was screened against gram-positive andgram-negative bacteria and fungi. It was also observed that the strongest antibacterial effects of oil were on Bacillus subtilis, Trichophyton mentagrophytes and Staphylococcus aureus that show potent cytotoxic activity in the tested carcinoma cell lines and breast equating to doxorubicin.
