This study was aimed at evaluating the chemical constituents, antioxidant and antibiotic activity of the TREo (terpene-rich essential oil) of the endemic plant species Teucrium sandrasicum O. Schwarz. The TREo obtained by hydrodistillation using a Clevenger-type apparatus and constituents was analyzed by gas chromatography/mass spectroscopy (GC/MS). The main components of the TREo were detected as beta-pinene (41.72%), a-pinene (13.95%), germacrene-D (10.68%) and sabinene (9.99%). Antioxidant capacity of TREo was tested the method Trolox Equivalent Antioxidant Capacity (TEAC) assay in vitro.
The antibiotic assay of the TREo on ten pathogenic bacteria including Escherichia coli MC-4100, Citrobacter freundi NRRL-B 2643, Providencia stuartii, Proteus vulgaris NRRL-B-123, Pseudomonas aeruginosa NRRL-B-2679, Enterobacter aerogenes NRRL-B-3567, Bacillus licheniformis NRRL-B- 001, Staphylococcus aureus ATCC-33862 was examined with agar disc diffusion method.
