Composition of the essential oils of Sideritis cladestina ssp Cyllenea and Sideritis sipylea

Abstract

The quantitative composition of the essential oils from two different Sideritis (Labiatae) species (S cladestina spp cyllenea and S sipylea) is reported. Over 80 components have been identified in each species by means of GC and GCMS analysis, and a number of substances have been identified for the first time in these essential oils.

Biological activities of the extracts of two endemic Sideritis species in Turkey

“…These species are known to have pharmacological, antiinflammatory, antimicrobial and antioxidant activities (Gergis et al, 1989;Aligiannis et al, 2001;Hernandez-Perez & Rabanal, 2002;Koleva et al, 2003;Tunalier et al, 2004;Ozkan, Sagdic, Ozcan, Ozcelik, & Unver, 2005;Gabrieli et al, 2005;Tsaknis & Lalas, 2005). Linearol, foliol, epicandicandiol and siderol which Available online at www.sciencedirect.com Innovative Food Science and Emerging Technologies 9 (2008) 80 -84 www.elsevier.com/locate/ifset are found in Sideritis species were investigated for antibacterial activities and epicandicandiol had the highest antimicrobial activity against Escherichia coli (Kilic et al, 2003).…”

“…These species contain many bioactive components such as β-pinene, α-pinene, siderol, sideridiol, sabinene, linearol, foliol, epicandicandiol, siderol and ent-7α,18-dihydroxy-15β and 16 β-epoxykaurane (Gergis, Argyriadou, & Poulos, 1989;Venturella, Bellino, & Marino, 1995;Gomez-Serranillos et al, 1998;Aligiannis et al, 2001;Aboutabl et al, 2002;Kilic, Yildiz, Goren, Tumen, & Topcu, 2003;Tunalier et al, 2004;Gabrieli, Kefalas, & Kokkalou, 2005). According to main components in essential oil, Sideritis species were classified as containing monoterpene hydrocarbons, oxygenated monoterpenes, sesquiterpene hydrocarbons, diterpenes and others (Kirimer, Tabanca, Ozek, Tumen, & Baser, 2000).…”

“…The final stage, in which both head cells have been divided giving a four celled head. Mateo et al 1983Mateo et al , 1984Mateo et al , 1988Komaitis et al 1985;Koedam 1986;Kokkalou 1987;Gergis et al 1989;Kokkini et al 1989).…”

Essential Oil Composition of ThreeSideritisSpecies Used as Herbal Teas in Turkey

“…The oil of Sideritis dichotoma from Turkey contains predominantly α-pinene and βpinene 21 whereas in the oil of S. germanicopolitana myrcene, sabinene and β-pinene were found to be the main volatile substances 20 . The essential oil isolated from S. cladestina and S. sipylea presents also comparatively high amounts of α-pinene, β-pinene, myrcene and limonene 12 . Baser et al 15 described α-and β-pinene as well as carvacrol as main essential oil components of Sideritis scardica Griseb.…”

“…In the past several studies on essential oils of Sideritis species have already been carried out [10][11][12][13][14][15][16][17][18][19][20][21] . Koedam 6 has reported the presence of β-copaene, α-pinene, δ-cadinene, βpinene, β-caryophyllene and limonene.…”
