The Composition of the Essential Oil of<i>Teucrium stocksianum</i>from the United Arab Emirates

Tecurium is a plant which belongs to the family Lamiaceae (Labiataea). This study was conducted in order to investigate the phytochemical composition of the leaves of Tuecrium mascatenses grown in Oman. The volume of the isolated oil was 1.2 ml 0.5 % w/w. Thirty two compounds were detected. The main constituents were limonene (17.2 %), linalool (12.4 %), α-pinene (10.1 %), β-eudesmol (10.1 %), unknown (7.6 %), linalyl acetate (4.3 %) bergamotene (4.3 %), β-pinene(3.5 %) and β-selinene (2.5 %).

Yousuf et al, have reported differences in the number of chemicals and relative concentration of chemicals in the same specie from same geographic location, but collected in different years [21]. Sesquiterpenes (59%) were found more than monoterpenes (40.97%) in this study.…”

BackgroundMedicinal plants are used for the treatment of different diseases in almost all cultures. Teucrium species grow wildly at different geographical locations around the world. Teucrium stocksianum is used in folk medicine for the treatment of diarrhea, cough, jaundice and abdominal pain. Scientific study on Teucrium stocksianum shows that it possesses anthelmintic, cytotoxic and antispasmodic activity. The aim of our present study is to identify the chemical composition and antinociceptive potential of the essential oil extracted from Teucrium stocksianum bioss.MethodEssential oil (EO) from the aerial parts of Teucrium stocksianum were extracted by hydrodistillation process. The qualitative and quantitative composition of essential oil was determined with Gas chromatography/Mass spectrometer. Antinociceptive activity was determined by acetic acid induced writhing method. Percent inhibition of writhes of the test concentration was determined by comparing it with that of control. Tween-80 emulsion 2.5% (5 ml/kg b.w) was used as a control while Diclofenic sodium 50 mg/kg (b.w) was used as a standard drug.ResultsThe chromatogram of the essential oil of Teucrium stocksianum shows differences both qualitatively and quantatively from essential oil composition reported in other countries. Hydrodistillation of Teucrium stocksianum yielded 0.4% (v/w), pale yellowish oil on dry basis. A total of 26 chemicals were identified by GC-MS accounting for 90.28% of the oil. The major components of essential oil were δ-cadinene (12.92%), α-pinene (10.3%), myrcene (8.64%), β-caryophyllene (8.23%), germacrene D (5.18%) and limonene (2.36%). Essential oil of Teucrium stocksianum has shown outstanding antinociceptive activity. It has been observed that increase in percent writhe inhibition (PWI) occurred from 20-80 mg/kg (b.w) and maximum writhe inhibition has been noted at a concentration of 80 mg/kg (b.w), but PWI decreased at 160 mg/kg, which may be due to some toxic effect of higher dose. ED50 value for Teucrium stocksianum was calculated as 31.5 ± 1.72415 mg/kg (b.w).ConclusionOur results indicate that there is a lot of variation in the composition of essential oil of Teucrium stocksianum boiss, which may be due to different climatic and experimental conditions. Secondly, the essential oil possesses strong antinociceptive activity and could be used in analgesic preparations especially for topical use.

The composition of the essential oils obtained from the air-dried Teucrium chamaedrys L. subsp. chamaedrys, Teucrium orientale L. var. puberulens, and Teucrium chamaedrys L. subsp. lydium (Lamiaceae) were analyzed by GC-MS. Thirty-six, 35, and 33 components were identified in the essential oils, and germacrene D (16.7%) was the most abundant constituent in T. chamaedrys subsp. chamaedrys, and b-caryophyllene was the most abundant component in both T. orientale var. puberulens and T. chamaedrys subsp. lydium in the ratios 21.7% and 19.7%, respectively. The isolated essential oils of the plants were tested for antimicrobial activity and showed moderate antibacterial activity against Gram-positive and Gram-negative bacteria, but no antifungal activity was observed against two yeast-like fungi.
