Essential oil composition of Taraxacum officinale

Abstract

The gas chromatography-mass spectrometry (GC-MS) analysis of essential oil obtained by hydrodistillation from the flower of Taraxacum officinale L. revealed the presence of 25 compounds with 1,3-dimethylbenzene, 1,2-dimethylbenzene, 1-ethyl-3-methylbenzene, heneicosane and tricosane as the main components.

Ethnobotany of the genus Taraxacum—Phytochemicals and antimicrobial activity

“…Identification and characterization of the essential oil from T. officinale florets have been carried out, showing 25 compounds belonging to various chemical groups: straight chain aliphatic hydrocarbons (nonadecane, hexadecane, heneicosane, pentadecane, tricosane, eicosane, and 1‐tridecyne), branched aliphatic hydrocarbons (2,5,5‐trimethylheptane and 6‐ethyl‐2‐methyloctane), esters (benzyl benzoate), alkylated benzenes (1,3‐dimethylbenzene, 1,2‐dimethylbenzene, 1‐ethyl‐3‐methylbenzene, and 1‐hydroxymethyl‐4‐methylbenzene), alcohols (2‐nonen‐1‐ol, 1,9‐nonanediol, and 1‐tridecanol), aldehydes (octanal, phenylacetaldehyde, 2‐methylbenzaldehyde, nonanal, pentadecanal, and 10‐undecenal), and ketones (5‐methyl‐2‐hexanone and hexadecanoic acid) as reported in Table (Bylka et al, ). To the best of our knowledge, other species of the genus Taraxacum have not been analysed yet for their essential oil content.…”

Identification of the components of the essential oil from Trollius europaeus flowers

“…for Aedes aegypti causing yellow fever) (Dekker et al 2011). Nonanal-alkyl aldehyde, a common component of essential oils, was present in the oils extracted from Olea europaea L. fruits (Jiménez et al 2004), the essential oil of Taraxacum officinale flowers (Bylka et al 2010), and the peel of Citrus limon and C. sinensis (Gruenwald et al 2004). It also occurs in the following Ranunculaceae species: Trollius europaeus, Anemone sylvestris, Aquilegia canadensis, A. chrysantha, A. glaudulosa, Caltha palustris, Pulsatilla rubra, P. vulgaris, Ranunculus acris, R. gramineus, and R. platnifolius (J} urgen and D} otterl 2004;Ibanez et al 2010).…”

“…The hydrocarbons hexadecane and eicosane, commonly found in essential oils (Taraxacum officinale, Coriandrum sativum, Hypericum hircinum), occurred in the greatest amount, i.e. 20.03 % of the total amount of the oil (Kumar Dwivedi et al 2010;Bylka et al 2010;Maggi et al 2010).…”

Taraxacum mongolicum 蒲公英 (Pugongying, Dandelion)

“…Vitamin A, B, C and D as well as potassium were found in both root and leaves, as well as was potassium [12]. Meanwhile, 1,3-dimethylbenzene, 1,2-dimethylbenzene, 1-ethyl-3-methylbenzene, heneicosane and tricosane were identified as the primary volatile compounds from the T. officinale flower [13].…”
