The genus Anthemis L. belongs to the family Asteraceae, is the second largest genus in the Compositae family, tribe Anthemideae, about 130 species of genus Anthemis occur throughout the world consists of 39 annual and perennial species distributed all over of Iran. According to literature, this species was not the subject of research up to nowtherefore its chemical composition is not well known. In this research three samples of Anthemis coelopoda . were collected from Gilan province, in the 2020. specimen is deposited in Central H and analyzed by GC and GC/MS. Main components from sample one Gilan: Loshan, before Hanifa Imamlower were β- calacorene 35.9%, Elemicin 24.0% and n-dodecanol 8.8% and in leaf were β- calacorene 26.8%, elemicin 13.9% and n-dodecanol 11.8%, and essential oil yield from flower were 0.04% and leaf were 0.03%. Main components from sample two Gilan: southwest of Rudbar, Lake 1181 meters high, in flower were γ- cuprenene 18.2%, n-dodecanol 13.8% and geranyl propanoate 7.4% and in leaf were n-dodecanol 13.5%, - terpinen-7-al 10.8% and geranyl propanoate 10.2%, and essential oil yield from flower were 0.10% and in lead were 0.07%. Main components from sample thee Gilan: Loshan, before Hanifa Imamzadeh, near the cement mine, 801 meters high, in flower were n-dodecanol 11.8%, - terpinen-7-al 9.3% and Cumin aldehyde 8.8% and in leaf were n-dodecanol 14.9%, - terpinen-7-al 11.1% and 5-hydroxy isobornyl isobutanoate 10%, and essential oil yeild from flower were 0.09% and in leaf were 0.06%. Sampling simultaneously on one day from three different areas (Samples 1 and 3 were collected from one area but at a great distance) their essential oils were examined for chemical composition and the results indicate different combinations and amounts in a species. This difference can be the result of differences in soil type and different plant water uptake.

In order to study the response of concentration and composition of essential oil of coriander (Coriandrum sativum) to cattle manure and nitrogen fixing bacteria, an experiment was conducted as factorial experiment in the base of randomized complete blocks design with twelve treatments and three replications at homand research station in Damavand of Iran in 2010. The factors were cattle manure in four levels (5, 10, 15 and 20 ton/ha) and nitrogen fixing bacteria in three levels (inoculation with azotobacter, inoculation with azospirillum and inoculation together). Results showed that the highest essential oil content and linalool and alpha pinene in essential oil were obtained with application of 10 ton/ha cattle manure. The maximum gamma terpinene and the minimum geranyl acetate in essential oil were obtained after applying 15 ton/ha cattle manure. Nitrogen fixing bacteria also showed significant effects on linalool, alpha pinene and geranyl acetate in essential oil (except essential oil content and gamma terpinene in essential oil) as the highest linalool in essential oil in treatment of inoculation with azotobacter, the maximum alpha pinene in essential oil in treatment of inoculation with azospirillum and the maximum geranyl acetate in inoculation together (azotobacter & azospirillum) were obtained.

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.
