Cirsium arvense, known as “Kharlateh” or “Kangar Sahraee” in Iran, is a plant classified as an agricultural weed. Canada thistle is the common name for C. arvense. In this study we investigated the chemical composition of the essential oils in C. arvense using GC/Mass spectroscopy. Each of the aerial parts of the plant flower, leaf and stem was investigated separately. Nineteen compounds were detected in the flower part, accounting for 96.5 % of the total oil. The main compounds are α-bisabolol (17.4 %), hexacosane (12.6 %), δ-cadinene (9.7 %). The leaf oils contained 12 compounds (99.7 % of the total oil), of which the three main compounds were α-bisabolol (34.8 %), δ-cadinene (20.7 %) and β-selinene (15.6 %). Twelve components (96.6 %) were also detected in the stem, including α-bisabolol and δ-cadinene, which account for 45.8 % and 23.8 % respectively. We also studied antibacterial activity C. arvense methanolic and hexanoic extracts. The results indicated that the plants hexane and methanol extracts showed antibacterial activities.
