Rosmarinus officinalis is one of the most important medicinal and aromatic plants around the world. Essential oil as a weapon against biotic and abiotic stresses plays an important role in essential oil bearing plants. In this study the essential oil content and constituent of plants containing bacterium-gall on the shoots and crown was compared with non-contaminated plants. Essential oil percentage was extracted by hydro-distillation using Clevenger trap. Identification of the essential oil compounds was done by GC/MS. Results in essential oil percentage showed that, contaminated plants were relatively lower than that of non-contaminated plants per 100 grams of dry leaves. GC/MS also, verified that α- pinene and Camphor, respectively were 1.43% and 7.02%, more in contaminated plant than non-contaminated plant. In addition, Berbenone (18%), was the most common constituent which had been observed only in contaminated rosemaries. The analysis of leaf extract using HPLC, showed that the content of rosmarinic acid of healthy plants was significantly lower than that of contaminated plants. In addition, contaminated plants had total phenol and flavonoid compounds as well as antioxidant activity in the highest amount. Based on the obtained results, it can be concluded that, gall bacteria had influence on the phenolic components which are known as secondary metabolites in this medicinal plant and phenolic derivatives may be modified in quantity and quality by the affection of this biotic stressor, this could be considered as an application for further usage in metabolic culture.

Juniperus sabina L. is normally low shrub with procumbent or obliquely ascending branches, or rarely a small tree to about 4 m, monoecious or dioecious. Juniperus sabina L. is a medicinal plant used in folk medicine as an abortive. Its lignanes have antineoplastic and antiviral activity, and also essential oil of Juniperus sabina L. has shown antibacterial and antifungal activity. The aim of this research is to extract and measure the chemical compounds of essential oils of fruits and aerial parts of the plant Juniperus sabina L. which are collected from the North Highlands located in the Mazandaran province. In this study, the components of Juniperus sabina L. (fruits and aerial parts), after extraction essential oils by Clevenger apparatus, their compounds were analysed and identified by GC/MS. Essential oils from fruits of the Juniperus sabina L., were shown 27 compounds that the Sabinene in 50.31% maximum, and α-Thujene with 0.32% were the lowest amounts in the oils. While the essential oils from aerial parts of Juniperus sabina L. 40 compounds were identified, that Sabinene by 36.59% was the highest amount and α-Thujene by 0.11% has at the lowest percentage.
