Chemical composition of the essential oil from aerial parts of Stachys palustris L. (Lamiaceae) growing wild in Southern Italy

2007

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…

Volatile compounds of flowers and leale of Sideritis italica (Miller) Greuter et Burdet used as mountain tea

2010

Sideritis italica (Miller) Greuter et Burdet (Lamiaceae), widely used in ethnopharmacological medicine, occurs in Southern Italy and Sicily. The phytochemical composition of the essential oils of S. italica flowers and leaves, harvested in Piano Battaglia (Sicily), was analysed by GC and GC-MS. Of the 51 compounds, 43 in the oil from flowers and 29 in the oil from leaves were identified. Kaur-15-ene (20.0%) was recognised as the main constituent of the oil from flowers, together with -cubebene (12.1%), -pinene (8.5%), (Z)-nuciferol (6.5%), tricyclene (4.5%) and -bisabolol (4.0%). In the oil from leaves, p-methoxyacetophenone (26.0%) prevailed, as did hexadecanoic acid (21.3%), followed by n…

Chemical Composition of the Essential Oil of Teucrium flavum ssp. flavum from Zakynthos, Greece

2012

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%).
