CHEMICAL COMPOSITION OF THE ESSENTIAL OILS OF SOME TAXA OF THE GENUS CLINOPODIUM (LAMIACEAE) FROM SICILY
The genus Clinopodium L. (Lamiaceae) is known for its medical uses in folk medicine and as a spice in Italian food. Recently, several taxa previously assigned to Satureja L. and Calamintha Mill. have been transferred to this genus (1). Pharmacological studies reveal, for instance, that Calamintha nepeta (L.) Savi [Clinopodium nepeta Kuntze subsp. nepeta], commonly known as “nepetella”, exhibits cholagogue, expectorant, sedative and antibiotic properties (2); furthermore, the essential oil of its aerial parts showed an antifungal activity (3). The apical flowering parts and leaves of Clinopodium vulgare L. are used in popular medicine for their carminative and emmenagogue properties (1); rec…
Chemical composition of the essential oil from aerial parts of Stachys palustris L. (Lamiaceae) growing wild in Southern Italy
The paper reports the composition of the essential oil from aerial parts of Stachys palustris L. (Lamiaceae) from Southern Italy. The essential oil was extracted by hydrodistillation from selected plants and its chemical composition was determined by the GC-MS system on two fused- silica capillary columns of different polarity. The mass fraction of oil was 0.21 % on a dry weight basis. Altogether, 92 compounds were identified accounting for 93.6 % of the total oil, which was characterized mainly by carbonylic compounds (25.4 %), fatty acids and their esters (24.2 %), along with sesquiterpenoidic compounds (16.0 %) and phenols (11.2 %). The major components of the sample were caryophyllene o…
Chemical Composition of the Essential Oil of Teucrium flavum ssp. flavum from Zakynthos, Greece
Essential oil extracted from dried aerial parts of Teucrium flavum ssp. flavum harvested in Zakynthos, Greece, was analysed by gas phase chomatography (GC) and gas chomatography mass spectrometry (GC-MS). The main constituents were caryophyllene (13.5%), caryophyllene oxide (8.5%), 4-vinyl guaiacol (6.0%) and α- humulene (5.0%).
