Исследован состав летучих компонентов листьев и антимикробная активность их эфирных масел у представителей сем. Lauraceae Juss., культивируемых в оранжереях, в отношении бактериальных шаммов: Bacilus polymyxa (Prazmowski) Mace, Bacillus megaterium de Bary, Staphylococcus saprophyticus Shaw et al., Pseudomonas fluorescens Migula, Pseudomonas putida Trevisan, Escherichia coli Castellani and Chalmers. Показано, что терпеноид камфора и ее фракции являются общими компонентами в составе летучих соединений листьев у представителей данного семейства, а их долевое содержание видоспецифично. Помимо доминантных компонентов: камфоры и ее фракций  антимикробную активность эфирных масел листьев определяют такие соединения, обладающие сильным токсическим эффектом в отношении патогенных бактерий и грибов, как сесквитерпен альфа-кубебен (2,30  %) в листьях Cinnamomum tamala и эвгенол (6,22  %) в листьях Laurus azorica.

The composition of leaf volatiles and the antimicrobial activity of essential oils of the representatives of the family Lauraceae Juss. cultured in the hothouse against Bacilus polymyxa (Prazmowski) Mace, Bacillus megaterium de Bary, Staphylococcus saprophyticus Shaw et al, Pseudomonas fluorescens Migula, Pseudomonas putida Trevisan, Escherichia coli Castellani, and Chalmers bacterial strains are studied. It is shown that terpenoids camphor and its fractions are the common components in the composition of volatile compounds of the leaves of the representatives of the family Lauraceae Juss. and its percentage is species-specific. The antimicrobial activity of essential oils determines the dominant components in addition to camphor and its fractions, as compounds having a strong toxic effect against pathogenic bacteria and fungi such as sesquiterpene alpha-cubebene (2.30  %) of Cinnamomum tamala leaves and eugenol (6.22  %) in Laurus azorica leaves.
