Environmental factors including temperature and anticipation have critical impact on vegetative and reproductive growth as well as secondary metabolites and quantity and quality of essential oils in medicinal plants. In this study, phytochemical characteristics of German chamomilelandraces collected fromthree watershed areas of Kaleibarchai, Hajilarchai, and Mardanagim of Arasbaran, Iran was surveyed using plotting method. Foliar essential oils were extracted by hydro-distillation using Clevenger apparatus and their yield and compositions were determined using gas chromatography and gas chromatography mass spectrometer methods. On the whole, 22 components were identified in German chamomile essential oils with α-bisabolol, Camazulene, α-phellandrene, E- β-Franesol, Z-E- Feranesol, and α-bisabolol oxide as the most important identified components. High temperature and anticipation caused increasing of α-phellandrene, α-bisabolol oxide Z-E- Feranesol in Kaleibarchai region. Also, low anticipation in Hajilarchai increased Camazulene and E- β-Franesol. On the other hand, low temperature in Mardanagim increased Camazulene and α-bisabolol oxide in collected samples. Therefore, collection of German chamomile from Mardanagim for high amounts active medicinal ingredients is recommended.
