GC-MS Analysis of Essential Oil and Volatiles from Aerial Parts of Peucedanum tauricum M.B. during the Phenological Period

Widespread worldwide Peucedanum plants (Apiaceae) have been used for centuries as plant medicines. The polymorphism of this genus is consistent with chemotaxonomically and therapeutically significant differences in the composition secondary metabolites. GC-MS tauricum M.B. volatiles from headspace (HS) hydrodistilled essential oil (HD), both obtained simultaneously flowers (FL), immature ripe fruits (IF, MF) leaves (L1-L3) collected at time harvesting generative organs, show chemical profiles HS HD same parts plant, between organs (FL, IF, MF vs. L1-L3). presented studies on variability biometabolites phenological period indicated optimal time, focused two molecular chemotaxonomic markers PT; guaia-1(10),11-diene guaia-9,11-diene (in iHD 25.5–32.1% 26.8–33.6%; their 29.4–41.3% 25.0–29.4%, respectively). This first report analysis fresh aerial sp. which was performed during vegetation period. importance, possible limitations, an evaluation tool useful chemotaxonomy also discussed.
