Full Length Research Paper
Anti-bacterial and anti-fungal activities of the isolated constituents from Cirsium arvense were evaluated. These five compounds namely α-tocopherol, 9, 12, 15-octadecatrienoic acid, tracin, hispidulin and luteolin were isolated from the ethyl acetate soluble fraction of the methanolic extract of the plant. Their structures have been identified by electrochemical impedance spectroscopy (EIS), high resolution resonance ionization mass spectrometry (HR-EIMS), 1H-NMR and 13C-NMR spectroscopic methods. The antibacterial and antifungal activities of these compounds were tested; compounds 3, 4 and 5 shows good activities.
Key words: Cirsium arvense, fractionation, isolation, antibacterial activity, antifungal activity.
