Abstract
The volatile profiles (VOC) and the essential oil (EO) composition from the aerial parts of Salvia broussonetii were analysed. Sesquiterpene hydrocarbons dominate the VOCs from leaves (95.7%) and flowers (67.6%), followed by monoterpene hydrocarbons (2.6 and 29.7%, respectively). The main common compounds are germacrene D, β-bourbonene, α-pinene, α-copaene and α-gurjunene, even if with divergent relative abundances. In the leaf EOs the sesquiterpenes prevail, even if not overwhelmingly (about 50.0%), followed by monoterpenes (23.0–35.0%) and by minor fractions of diterpene hydrocarbons and non-terpene derivates. The most abundant common compounds across the two sampling periods are α-pinene, β-pinene, isobornyl acetate, α-gurjenene, germacrene D and bifloratriene. A morphological characterisation of the trichomes responsible for the productivity in terpenes was also performed. Four different morphotypes were observed on the above ground organs of S. brussonetii: peltates and capitates of type II and III resulted the only producers of volatile substances.Pubblicazioni consigliate
