Abstract
Medicinal and aromatic plants are offered in a wide variety of products on the world market. Iran, located in Middle East, played a key role in connecting various cultures and civilizations. Ethno-herbal and phyto- chemical dates back to a long time ago and a number of writings regarding this issue are left by great physicians e.g. Avicenna and Rhazes. Iranian botanists have recognition of around 1450 genera and 8000 species which nearby 2000 species are endemic. Iranian traditional medicine had cited pharmaceutical dosage forms, e.g. powders, syrups, ointment, extracts, powders, mucilage’s, nectars, etc. In this presentation Phyto-chemical screening of Aromatic plants, e.g. Rosa damascena, Thymus spp, Anthemis spp, Hypercom spp, are reviewed. Also the effect of ecological zone of growing, methods of extraction and identify their components are in our project. Rosa damascena cultivated in extensive zone of Iran and produce rose water and essential oils out of it. In this research, few samples of essential oil were extracting by different methods, e.g. traditionally, industrial and laboratory scales. Samples of oil were analyzed by GC and GC/MS. The main constituents of oil by traditionally , Ghatran Gool Co. were n-nonadecane (33.1%); geraniol (14.6%), n-heneicosane (13.2%); Kashan sample were shown, n-nonadecane (33%); n-heneicosane (18.1%); mehyl hexadecane (12.9%), Laboratory essential oils samples were extracted by two hydro distillation method which designed by authors in Research Institute of Forests and Rangelands which were named plan-1 and plan-2. The main isolated constituents in plan-1 were geraniol (21.8%), n-nonadecane (21.3%); citronellol (12%), with yield of (0.015%) and in plan-2 were n-nonadecane (21.8%); geraniol (19.1%), citronellol (15%), with yield of (0.023%).in other studies, investigated the effect of storage and time on essential oil composition in normal temperature of Rosa demascena were down. We used different vessels e.g. glass, color glass and aluminum quality. Main components of Primary essential oils were citronellol (33.5%), cis-p-menth -2-en-1-ol (7.3%) and geraniol (7.2%). Storage in three months in simple glass in refrigerator were better than others methods. Storage of essences in six months of periods of time in simple glass and normal temperature is better than other. In this presentation also shown how verity, ecotype, different part of plants and methods, effected on the essentials oil of other aromatic plants name in up.
