Effect of Morphogenetic Variability on Volatile Oil Composition of Immortal Flower (Helichrysum arenarium subsp. rubicundum)

Abstract

In this study aimed to determine the effects of morphogenetic variability on the essential oil composition of immortal flower (Helichrysum arenarium subsp. rubicundum) plants collected from Subaşı village of Köse district of Gümüşhane province, Türkiye. The aromatic components in the essential oil of the plant were determined using Gas Chromatography Mass Spectrometry device attached with solid phase microextraction. Totally 69 different components were identified. The main components of the volatile oil were methyl p-tert-butylphenylacetate (17.57%), ?-caryophyllene (13.42%), undecly alcohol (10.33%), phtyone (9.01%), ?-cadinene (8.89%), ?-cadinene (7.74%) and tetradecane (5.64%). Alloaromadendrene (3.24%), ?-humulene (3.07%) and caryophyllene oxide (1.79%) were found only in the flower part, acetyl tributyl citrate (3.52%) and ?-pinene (1.89%) only in the leaf part and phthyol acetate (4.70%) and tridecylaldehyde (1.26%) only in the stem part. The main reasons for these differences include genetic and ecological factors. Factors such as the use of different organs of the plant (morphogenetic variability) also play an important role. Similarly, the differences in the essential oil ratios and essential oil components of plants are also thought to be due to these factors.
