The content and composition of essential oil in fresh leaves of Pelargonium radula (Cav.) L'Herit (Geraniaceae) was investigated. Essential oil was separated by hydrodistillation and analysed by GC and GC-MS during the whole vegetative cycle of the plant. Essential oil largely consists of cyclic monoterpenes with oxygen (65.3-75.0%) and their oxides and esters (11.2-19.0%). The main component of essential oil was geraniol (40.5-50.5%). Other important monoterpenes found include citronellol, i-menthone, citronellyl formate, and geranyl formate. Sesquiterpenic compounds were found in traces, whereas the only phenylpropane compound identified was eugenol.
