title: Aroma Profile of Rubus ulmifolius Flowers and Fruits During Different Ontogenetic Phases.
abstract: The chemical composition of spontaneous volatile emission from Rubus ulmifolius flowers and fruits during different stages of development was evaluated by HS-SPME-GC/MS. In total, 155 chemical compounds were identified accounting 84.6 - 99.4% of whole aroma profile of flowers samples and 92.4 - 96.6% for fruit samples. The main constituents were α-copaene, β-caryophyllene, germacrene D, (E,E)-α-farnesene, 1,7-octadien-3-one,2-methyl-6-methylene, tridecane, (E)-2-hexenol acetate, (E)-3-hexenol acetate and cyperene. The results give a chemotaxonomic contribution to the characterization of the VOCs emitted from flowers and fruits during their ontogenic development.
