The steam distillation method was used to obtain samples of essential oil of Pseudotsuga menziesii introduced in Republic of Belarus. More than 20 components have been identified and determined in the essential oil of Pseudotsuga menziesii by gas liquid chromatography. The dominant components are bornylacetate (~25–30 %), camphene (~14–15 %), α-pinene (~7–8 %), β-pinene (~8–10 %). Distribution of the enantiomers of the main components of Pseudotsuga menziesii essential oil are shown. It was determined the optical purity of oil to (–)-bornylacetate. The antimicrobial activity of Pseudotsuga menziesii essential oil was detected in relation to test cultures of gram-positive and gram-negative bacteria. Gram-positive bacterial cultures were more sensitive to the inhibitory effect of essential oil. The effect of the optical activity of essential oil dominant components on antimicrobial properties is shown.
