عنوان انگلیسی Comparison of Essential Oils Compositions of Eryngo (Eryngium caucasicum) in Different Parts of Plant in Two Growth Conditions
چکیده انگلیسی مقاله Eryngium caucasicum Trautv. (Apiaceae) is a perennial herbaceous plant with about one meter height, an endemic species that has been distributed in the northern parts of Iran. The plant leaves are normally used in medicine and food industries in Iran.The plant has several medicinal properties including enforcing generative power, diuretic, lenitive and appetizer. In this research differents parts of plants (flower, leaves, stem and roots) from two locations littoral and unlittoral early reproductive phase are collected. The essential oils obtained by three methods of distillation (water distillation, steam distillation and hydro-steam distillation), the composition of essential oils was analyzed by gas chromatography (GC) and gas chromatography, coupled to mass spectrometry (GC-MS). Essential oils content in flower of plants from littoral and unlittoral locations in hydrodistallation method with mean of 0.32% and 0.38% and water and steam distillation with 0.176% and 0.21% in hydro-steam distillation with 0.06% and 0.09%, respectively. Essential oils content in fresh leaf also were with hydrod-istallation method with mean of 0.13% and 0.19% and steam distillation with 0.1% and 0.14%, hydro-steam distillation 0.1% and 0.16%, respectively. Essential oils content in dry leaf of plants with hydro-distallation method with mean of 0.17% and 0.32% and steam distillation 0.053% and 0.087%, in hydro-steam distillation with mean of 0.1% and 0.16%, respectively. Main components in flower were allo-aromadendrene (48.7 up to 71.6%), trans-calamenene (11 up to 18.2%), and dehydro abietal (1.2 up to 10.9%), respectively. Main components on fresh and dry leaf from littoral location were allo-aromadendrene (1.5 up to 30.6%), dihydro tagetone (2.9 up to 19.8%), (E,E)-farnesol (0.5 up to 28.3%), respectively. Main components on fresh and dry leaf from unlittoral location were allo-aromadenderene (13 up to 33.2%), dihydro tagetone (1.8 up to 17.9%), α-calacorene (7.7 up to 23.1%), (E,E)-farnesol (12.1 up to 17.5%), respectively. Main components on stem from both location were dihydro tagetone (1.6 up to 9.4%), allo-aromadendrene (36.0 up to 67.4%), trans-calamenene (8.3 up to 16.2%), dehydro abietal (6.3 up to 19.5%), respectively. Main components on root from both location were n-octadecanol (43.5 up to 91%), dihydro tagetone (1 up to 4.9%), γ- cadinene (0.5 up to 1.4%), respectively.
