The Effect of Helichrysum pallasii on Essential Oil Composition of Ontogenetic Variability

Since the earliest times of human history, medicinal plants have been used and continue to be used in many areas such as disease prevention, treatment and food additives. Species belonging to the Helichrysum genus have many important properties such as antimicrobial, antibacterial, antiviral, antifungal, antioxidant and anti-inflammatory thanks to the components they contain, which vary depending on many factors such as location, climate and soil conditions. For this reason, in this study, the stem, leaf and flower parts of Helichrysum pallasii plant collected during the full bloom period from its natural habitat in Köse district of Gümüşhane province of Türkiye were used as plant material. The aromatic components in the essential oil of the plant were determined using the SPME (Solid Phase Microextraction) method in Gas Chromatography (GC-MS) device. 58 different components were found as a result of the analysis. The prominent components are; Methyl butyl phenyl acetate (16.04%), phtyone (11.05%), β-caryophyllene (10.47%), undecly alcohol (7.57%), 𝛿-cadinene (%7.36), γ-cadinene (5.32%), hexadecane (5.24%) and tetradecane (4.51%).
