Chemotaxonomy of Serbian Teucrium Species Inferred from Essential Oil Chemical Composition: the Case of Teucrium scordium L. ssp. scordioides

Abstract

The volatile constituents of Teucrium scordium L. ssp. scordioides, T. polium, and T. montanum, obtained by hydrodistillation, were investigated by GC-FID and GC/MS analyses. A total of 296 constituents were identified, representing 89.8-98.4% of the oil compositions. The oils of T. polium and T. montanum consisted mainly of sesquiterpenes (64.3 and 72.7%, resp.), with germacrene D (4; 31.0%) and δ-cadinene (10; 8.1%) as the main constituents, respectively. In contrast, the monoterpene menthofuran (1; 11.9%) predominated in the oil of T. scordium ssp. scordioides, and this clearly distinguished this species from the other Teucrium taxa investigated up to date. The chemistry of the volatiles of eight Teucrium taxa from Serbia and Montenegro were compared using multivariate statistical analysis, and this provided chemotaxonomically important conclusions.

Essential oil compositions of Teucrium fruticans, T. scordium subsp. scordioides and T. siculum growing in Sicily and Malta

“…The most abundant compound of the oil was caryophyllene oxide (25.8%), followed by a-pinene (19.4%) and b-pinene (8.5%), whereas among the sesquiterpene hydrocarbons the most representative products were b-sesquiphellandrene (5.9%) and (E)-b-caryophyllene (4.4%). Comparison of our data with the only analysis of the essential oil of this taxa, i.e., from plants collected in Serbia (Radulovi c et al 2012), showed a complete different composition of the oil. In fact, the latter one was characterized by the presence of menthofuran (11.9%), as the main component, and by a complex mixture of fatty acids and fatty acid-derived compounds (39.7%), being both totally absent in the Sicilian accession.…”

Essential oil composition and nutrient analysis of selected medicinal plants in Sultanate of Oman

“…It has been previously noted that the essential oil composition may vary greatly depending on the habitat, location, climatic conditions and soil biology [51] . This varying biospheric condition regulates the internal physiology of the plant to synthesize such diverse array of chemicals within the same species [52] .…”

Chemotaxonomic Study of Citrus, Poncirus and Fortunella Genotypes Based on Peel Oil Volatile Compounds - Deciphering the Genetic Origin of Mangshanyegan (Citrus nobilis Lauriro)

“…Recently, progress in chromatographic/spectral technique and software for automatically analyzing MS data, such as MzMine [6], MathDAMP [7], Tagfinder [8] and MetAlign [9], has remarkably facilitated chemotaxonomy and nontargeted functional genomics research [10], [11]. The former would play an important role in the study of taxonomy and has been used in chemotaxonomy studies of fungi and plants, and is a promising method for those highly hybrid plants and its closely related species, such as Citrus and its related genera [12]–[14].…”
