Chemical composition of the essential oils of wild helichrysum arenarium (L.) with differently colored inflorescences from eastern lithuania / A. Judzentiene in The journal of essential oil research, Vol. 18 N° 1 (Janvier-Fevrier 2006)

Moench. of natural populations from eastern Lithuania has been studied. Samples of leaves and inflorescences of different colors [yellow and orange (f. aurantiacum (Pers.) Bleck.)] were collected from the same growing localities at flowering stage. The oils were prepared by hydrodistillation and analyzed by GC and GC/MS. The 68 constituents identified comprised 73.8–90.7% of the total oil content. It was found that the principal constituents were: β-caryophyllene (in three inflorescence and one leaf oil), δ-cadinene (in two leaf oils), octadecane (in one leaf oil) and heneicosane (in one inflorescence sample). Monoterpenes and oxygenated monoterpenes made up 4.0–13.9%, aliphatic hydrocarbons 0.4–35.3%, and sesquiterpenes 24.7–71.2% of the oils.

The variability of the essential oil composition of wild ledum palustre L. shoots during vegetation period / R. Butkiene in The journal of essential oil research, Vol. 23 N° 1 (Janvier/Fevrier 2011) 

Public ISBD [article]  in The journal of essential oil research > Vol. 23 N° 1 (Janvier/Fevrier 2011) . - pp. 9 - 13 Titre : The variability of the essential oil composition of wild ledum palustre L. shoots during vegetation period Type de document : texte imprimé Auteurs : R.

Seven essential oils of shoots (without inflorescences and seeds) and one oil of inflorescence were obtained by hydrodistillation and analyzed by GC and GC/MS. Predominant constituents in all oils were ledol (21.0–32.2%) and palustrol (26.2–37.9%). The oils richest in ledol and palustrol were found in April and October. To evaluate the amounts of these compounds in the shoots, the percentages were related to the contents of the oils obtained from shoots. Calculated amounts of ledol and palustrol were largest in shoots during flowering in May. The inflorescence oil (11.4%) and shoot oil (7.5%) obtained from L. palustre during seed formation in June contained considerable amounts of myrcene. Cyclocolorenones (2.7–6.5%) were among six main constituents. Monoterpenoids 2-methyl-5-(3-furyl)-3-penten-2-ol, 5-(3-furyl)-2-methyl-1-penten-3-one (lepalone) and 5-(3-furyl)-2-methyl-1-penten-3-ol (lepalol) were found in all oils. The largest amounts of furyl compounds were produced by L. palustre in September (9.5%) and October (14.7%). Sixty-nine identified compounds comprised 95.7–99.3% of the oils.
