The aim of this work was to investigate the composition of essential oils isolated from fruits of <i>Peucedanum longifolium</i>, and <i>Rhizomatophora aegopodioides</i> (a species which was previously placed in the genus <i>Peucedanum</i>), as well as to compare the obtained results to those available for other previously investigated related species (including taxa which are also, according to some authors, excluded from the genus <i>Peucedanum</i>). Essential oils were obtained via hydrodistillation in a Clevenger-type apparatus and their composition was analyzed using GC-FID and GC-MS. To compare these data to those of previously investigated taxa, a chemometric approach was applied; the data were analyzed using multivariate statistical methods: non-metric multidimensional scaling (nMDS) and hierarchical cluster analysis. The most abundant in <i>P. longifolium</i> essential oil were monoterpenes (79.7%), mostly <i>α</i>-phellandrene (26.2%), <i>β</i>-phellandrene + limonene (21.0%) and myrcene (9.5%), followed by sesquiterpenes (18.3%), mostly germacrene B (9.5%). On the other hand, dominant in <i>R. aegopodioides</i> essential oil were non-terpenic aliphatic hydrocarbons (46.1%), mainly <i>n</i>-undecane (16.5%) and <i>n</i>-nonane (11.3%). In addition, this essential oil also contained a notable quantity of sesquiterpenes (25.1%), with (<i>E</i>)-sesquilavandulol being the most abundant (10.0%). The results of multivariate statistics revealed a clear separation of the essential oil composition of <i>R. aegopodioides</i> and <i>P. longifolium</i>, as well as of <i>P. longifolium</i> and <i>P. officinale</i>. The clustering of the samples of most of the taxa that do not belong to the <i>Peucedanum</i> in the narrow sense (<i>sensu stricto</i>) was also observed, which is in accordance with their recent inclusion in separate genera.
