Chemical Compositions of the Essential Oils and Headspace Volatiles of Seseli peucedanoides Plant Parts

Abstract

The chemical compositions of the essential oils of Seseli peucedanoides (M.Bieb.) Koso-Pol. inflorescences and leaves, isolated by hydrodistillation, and headspace volatiles, obtained by the static headspace method, were analyzed in detail by gas chromatography (GC) and GC/mass spectrometry (MS). In total, 74 constituents were identified, representing more than 98% of the observed GC peaks. The number of identified essential oil components obtained from the inflorescences was 63 while for the leaf essential oil it was 46. A much smaller number of compounds, 26 for inflorescences and 21 for leaves, were detected in the headspace samples. In both essential oils the most abundant compounds were the same, (E)-caryophyllene and germacrene D, only in different proportions. The main components in the headspace specimens were α-pinene and (E)-β-ocimene with (E)-caryophyllene and (Z)-3-hexen-1-ol also determined in significant percentages. The major class of compounds identified in the investigated essential oils was hydrocarbon sesquiterpenes with a share of over 80%, while the most dominant class of the headspace volatiles was hydrocarbon monoterpenes, which contribute slightly less than 80% of the total.

Chemical Composition and Evaluation of Insecticidal Activity of Seseli bocconei Essential Oils against Stored Products Pests

“…δ-Cadinene, as a main constituent, was reported only for the EOs of the stems of Seseli peucedanoides (M.Bieb.) Koso-Pol (collected in Serbia) [48], while the presence of the monoterpene hydrocarbon sylvestrene was not detected in any essential oil of the genus Seseli. Limonene, the second most abundant component of the oil from the flowers of S. bocconi, has been detected in good quantity in the flowers' oils of S. montanum ssp.…”

Impact of Climate Change on the Chemical Compositions and Antioxidant Activity of Mentha pulegium L.

“…Following the qualitative identification of major metabolite families, quantitative assays were conducted on secondary metabolites. These assays were carried out using established methodologies referenced in the research; − the quantification of these metabolites was achieved by employing established methodologies, which offer a reliable framework for accurately measuring and determining the levels or concentrations of the identified metabolites in the plant samples. These methods ensured the precision and reliability of the quantitative data collected during the study.…”

“…It should also avoid triggering biochemical reactions; inducing thermal degradation, oxidation, reduction, hydrolysis, and pH alterations; or causing the loss of volatile compounds. Achieving these goals necessitates a thorough consideration of various parameters and attributes during the extraction process …”

Composition of essential oils and headspace constituents of Artemisia annua L. and A. scoparia Waldst. et Kit.

“…[1][2][3] Even though headspace G-C is extensively used a limited number of papers is focused on the analysis of headspace volatiles obtained directly from the plant material under static conditions. [4][5][6][7][8][9][10][11] More papers are related to HS-SPME analysis some of which refer to A. scoparia 12 and A. annua. [13][14][15][16][17] Static headspace analysis of plants is a very fast and inexpensive method.…”
