| Experiment Detail |
The study was conducted in North-Central Anatolia under semi arid conditions. Seeds of 18 basil landraces (O. basilicum L.) were collected from local farms and home gardens in Turkey. To examine essential oil composition of the basil landraces without environmental influences, the plants were grown under identical (same environmental and soil conditions) conditions. Seeds were sown on a medium (1:1:1 washed sand, horse manure and field soil) in greenhouse conditions on March 25, 2003. Seedlings were grown until the 3-5 leaf stage. The seedlings were transplanted into pilots in the Gaziosmanpasxa University Experimental Research Station on May 15, 2003. The plants were harvested at the full blooming stage and dried at 35 ℃ for essential oil isolation.

| Factor Function |
Variation of essential oils in the landraces was subjected to cluster analysis, and seven different chemotypes were identified. They were (1) linalool, (2) methyl cinnamate, (3) methyl cinnamate/linalool, (4) methyl eugenol, (5) citral, (6) methyl chavicol (estragol), and (7) methyl chavicol/citral. Methyl chavicol with high citral contents (methyl chavicol/citral) can be considered as a 'new chemotype' in the Turkish basils.

| Experiment Detail |
The aerial parts (~35 cm) of each taxa growing wild in eight localities of Almeria province were collected in May 1996. All samples were collected at full flowering. Sideritis pusilla (Lange) Pau ssp. pusilla var. typica, Population/location (UTM): Los Matarines (30SWF7992); Sideritis pusilla ssp. pusilla var. carthaginensis Font Quer, Population/location (UTM): Rambla del Hacho (30SWF7178); Sideritis pusilla ssp. pusilla var. granatensis (Pau) Font Quer, Population/location (UTM): Gafarillos (30SWG8702); Sideritis pusilla ssp. almeriensis (Pau) Malagarriga var. typica, Population/location (UTM): Sierra de Gador, Cerro de los Lobos (30SWF3575); Sideritis pusilla ssp. almeriensis var. littoralis Font Quer, Population/location (UTM): Los Morales (30SWF6775); Sideritis pusilla ssp. almeriensis var. salina Font Quer, Population/location (UTM): Los Pedregales (30SWG7835); Sideritis pusilla ssp. flavovirens (Rouy) Malagarriga, Population/location (UTM): Velez Rubio, Cerro del Huezno (30SWG8965); Sideritis pusilla ssp. osteoxylla (Pau) Pallares, Population/location (UTM): Cabo de Gata, Cerro de S. Miguel (30SWF7165)

| Factor Function |
Monoterpene hydrocarbons, alcohols, sesquiterpenes and diterpenes were the main constituents in all samples. Among these, alpha-pinene (7.1-25.4%), sabinene (5.9-20.4%), fenchone (0.9-19.3%), limonene (1.2-7.4%) and 1,8-cineole (1.8-15.6%) were the major compounds. The results confirm that there are differences between varieties and subspecies, while cluster analysis revealed that the oil composition potentially has chemotaxonomical significance for this taxon.
