Eucalyptus Globulus Leaf Extract
The antibacterial activity of Eucalyptus globulus leaf extract was determined for 56 isolates of Staphylococcus aureus, 25 isolates of Streptococcus pyogenes, 12 isolates of Streptococcus pneumoniae and seven isolates of Haemophilus influence obtained from 200 clinical specimens of patients with respiratory tract disorders. Leaves contain 70-80% eucalyptol (cineol). Also includes terpineol, sesquiterpene alcohols, aliphatic aldehydes, isoamyl alcohol, ethanol, terpenes. Tannin is not so copious in the leaves as of many other Eucalyptus species. The kino, containing 28,7% kino tannin and 47,9% catechin contains the very antibiotic citriodourol. Fresh leaves contain caffeic and gallic acids, dry leaves, ferulic and gentisic, and quercetol, quercitrine, rutin, and a mixture of quercetol hyperoside and glaucoside. N-titriacontan-16, 18-dione was identified as the compound responsible for antioxidant activity in the leaf wax.
