Volatile Components in Sideritis scardica Griseb. Cultivar

Volatile components of nine Sideritis scardica samples from cultivar planted at different ecological conditions were studied by GC and GC/MS. Thirtyeight individual components in concentration exceeding 0.2% were used for comparison of the studied samples. They belong to mono-, sesquiand diterpenes, and their oxygenated derivatives, aromatic and aliphatic compounds. Domination of terpene hydrocarbons could be noted as their common feature. The essential oil composition showed significant chemical polymorphism of the S. scardica samples. A relation between the oil profiles, altitude and climatic zones was discussed briefly.
