بررسی استخراج و شناسایی ترکیب های شیمیایی اسانس گل محمدی ‭Rosa damascena ‬در پایه های مختلف کشت شده در استان خراسان رضوی (مشهد مقدس)

Due to survey of rate of yield ,percentage and compounts of essential oils, firty-six accesions of Roza damascena mill.were collected from different province and cultivated in Agricultural Resources Research Center of Torogh, Mashhad, since 2004. the survey was conducted as an statistic project in 3 replication. By randomized complete block design. Flower harvesting has been initiated since 2006 and extended for 3years (2006 until 2008). The composition of essential oils were studied at Research Institud of Forests and Rangelands. The result of variance analyzes and comparison of average of amounts(yield, percentage and composition of essential oils for total of accesions were significat(in level of one percentage). The most essential oils rate yield and percentage im study of three years belong to accesions of no. 15(from baluchestar) and the least rate belonge to accesions of no. 47 and no.52. Ten highest mounts(yield)and percentage of essential oils,were assigned. The superior accesions for amunt of essential oils were number of 15,17,16,37,4,23, 34,32and 33 and the superior accessions for percentage of essential oils,were number of 15,19,14,20,17,7,4,12,23and 9. the essential oils twenty and fifty compositions of essential oils were recognized at since 2006 and 2008, respectively. The most important of essential oils compoundes at since 2006 and 2007 were citronellol,geraniol,geranial,neral,n-hexadecanol,n-nonadecane,n-heneicosan. In addition,a meanixyful correlation was seen amount the flowers yield and essential oils in one percent level. Key words:essential oils, yield, percontag and compounts, accesion, corrolution.
