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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
