Chemical composition and antiphytoviral activity of essential oil of Micromeria graeca

Abstract

Phytochemical analysis of the essential oils of Micromeria graeca (L.) Rchb from Vis and Komiža on the island of Vis (Croatia) showed them to have a similar chemical composition. The oxygenated sesquiterpene α-bisabolol was a major component of both oils with percentages of 13.9% in the oil from Vis and 15.5% in the oil from Komiža. A comparison of the mean number of lesions on the essential oil-treated Chenopodium quinoa plants infected with satellite-associated cucumber mosaic virus (satCMV) with the corresponding control showed that the oil from Vis caused delay in the development and reduction of the number of lesions by 59.3%. The essential oil of M. graeca from Komiža was not effective in the reduction of satCMV infection.
