dc.description.abstract | In this study two Sideritis L. taxa from Turkey (Sideritis montana L.
subsp. montana and Sideritis vulcanica Hub.-Mor.) have been studied to
determine taxonomical classification based on chemical characters. For
this purpose hydro distilled essential oil aerial parts of Sideritis
montana subsp. montana and Sideritis vulcacina were investigated by GC
and GC-MS, forty and forty three compounds were identified representing
90.1 and 92.1 \% of the oil, respectively. The yield of oils are about
0.30 and 0.40 mL/100 g, respectively. beta-Caryophyllene (30.3 \%),
alpha-pinene (12.7 \%) and beta-pinene (10.6 \%) in S. montana subsp.
montana, alpha-pinene (15.5 \%), beta-caryophyllene (13.2 \%) and
1,8-cineole (9.9 \%) were identified as main components in S. vulcacina.
The chemical distribution of the essential oil compounds in the genus
pattern were discussed in means of chemotaxonomy and natural products. | |
