Composition of the Essential Oil of Helichrysum chasmolycicum Growing Wild in Turkey

Abstract

The chemical compositions of the essential oil obtained from the aerial parts of Helichrysum chasmolycicum were analyzed by gas chromatography and gas chromatography-mass spectrometry. From the 57 identified constituents, representing 66.55% of the oil, the main constituents of the oil were beta-caryophyllene (27.6%), beta-selinene (8.9%), alpha-selinene (8.4%), caryophyllene oxide (7.3%), and carvacrol (2.4%). The essential oil was almost totally characterized by sesquiterpene hydrocarbons such as beta-caryophyllene and alpha- and beta-selinene.

Volatolomics of Three South African Helichrysum Species Grown in Pot under Protected Environment

“…α-Selinene, instead, was the major component of the EO of H. araxinum , which showed also good amounts of the β-isomer [ 2 ]. Fair amounts of both the molecules were also detected in H. chasmolycicum P.H.Davis [ 24 ]. Interestingly, the high percentage of apocarotenoids (AC) in H. decorum (12.5%), mainly represented by hexahydrofarnesylacetone (5.5%), followed by the ionones trans -β-ionone (3.8%), dihydropseudoionone (1.4%), (E,E) -farnesylacetone (1.0) and dihydro-γ-ionone (0.8%).…”

Chemical composition of the essential oil of Helichrysum oligocephalum

“…The chemical constituents of the essential oils of different species of Helichrysum have been intensively investigated by many researchers [9][10][11][12][13][14][15]. β-Caryophyllene is the major constituent in the essential oils of many Helichrysum species such as H. chasmolycicum [9], H. cymosum, H. fulgidum [10], and H. melaleucum [11].…”

“…β-Caryophyllene is the major constituent in the essential oils of many Helichrysum species such as H. chasmolycicum [9], H. cymosum, H. fulgidum [10], and H. melaleucum [11]. α-Fenchene, selina-5,11-diene, spathulenol, and germacrene D-4-ol are other constituents reported as the main component of the volatile oils of H. faradifani [12], H. forsskahlii [13], H. amorginum [14], and H. splendidum [15] respectively.…”

Composition of the Essential Oils of Two Endemic Helichrysum Species in Turkey

“…In Turkey, this genus is represented by 30 taxa. Sixteen of them are endemic in Turkey and Helichrysum species are known as "altın çiçeği," altınotu," and "kovanotu" [3].…”
