| Abstract | ||
| Juniper is the most important native conifer in Iran. Juniper as one of the most resistant tree species to extreme conditions, frost (up to –40°C) and drought, plays important role in mountainous regions of Iran. In this study, by investigation on qualitative and quantitative characteristics of essential oils of leaves and berries (female cones), the effects of environmental factors were studied on metabolism of secondary products. The volatitale constituents of the Leaves and berries of male, female and male-female trees isolated by steam-distillation were analyzed by GC-MS. Results indicated that the amount of essential oil in berries is higher than that in leaves. Seasonal alteration of essential oil of berries differs from leaves. The essential oil of berries increase during growth period, however decreased in leaves. Besides drying has increasing effect on essential oil. In total 32 terpenoidic components were found that α-pinene, limonene, trans-verbenol, cis-verbenol, verbenone, Υ- elemone and elemol were the important ones. α-pinene up to 70% of essential oil content was the highest component. Seasonal alteration of each component was very variable. Drying effect can be valuable for isolation of components and commercial applications. | ||
