Comparison of essential oil composition of Stachys byzanthina C. Koch. in two habitats of Mazanda ran province
Abstract:
Quality and quantity of active ingredients of medicinal plants is mainly influenced by genetic factors but also environmental factors in the growth area can have a great impact. So that the amount and quality of a chemical plant, due to fluctuations in the metabolic activities of different environmental factors in different areas of habitat and altered. The purpose of this study flowered branches of species Stachys byzanthinac. Koch in June 2011 in full bloom, the height of 1800 meters above sea level the habitat range savad-kooh and Kojour Nowshahr in Mazandaran province by three points at random in each area of the plant the comments were collected. The samples collected were dried in the shade. 100 g of dried plant matter per sample, then weighed using hydro distillation (Clevenger apparatus) of oil was about 3 hours. The compounds identified in the essential oil by GC and GC / MS was performed. 49 results found in the essential oil composition of Stachys byzanthinac. Koch showed two regions. The main constituents were(E)-β-farnesene (18.64%), p-cymene (14.97%), 1-(1,5-dimethyl-4 hexenyl)-4- methyl- benzene (13.60%), germacrene-D (10.34%), levomenol (8.88%), 6,10,14 Trimethyl-2- pentadecanone (6.17%), cis-γ-bisabolene (3.74%), β-elemene (3.72%) and α-cedrane 3.41%) respectively. The main composition of essential habitat Kojour nowshahr seven respectively Isobutene (25.7%), α-longipinene (14.37%), germacrene-D (6.75%), p-Cymene 6.45%), 1-(1,5- dimethyl-4-hexenyl)-4 methyl-Benzene (5.33%), Levomenol (4.87%), hexenyl Cyclopentanone (3.13%).
