title: Antiphytoviral activity of essential oil from endemic species Teucrium arduini.
abstract: The essential oil of Teucrium arduini L. was characterized by a high concentration of sesquiterpene hydrocarbons (43.8%) of which beta-caryophyllene (19.9%) being the major compound, followed by oxygenated sesquiterpenes (19.6%) of which caryophyllene-oxide (14.6%) was dominant. When applied to plants of Chenopodium amaranticolor and Ch. quinoa for two successive days prior inoculation, the oil was effective in reducing lesion numbers on plants infected with Tobacco mosaic virus (25.7%) and Cucumber mosaic virus (21.9%). The main components of oil, beta-caryophyllene and caryophyllene oxide showed potent antiviral activity against CMV, but weak activity against TMV infection.
