The extract from clematis has been prepared and its corrosion inhibiting capacity for steel Q235 in simulated industrial circulating cooling water investigated. The results by UV-visible spectroscopy ,electrochemical polarization curves,electrochemical impedance spectroscopy and weight loss methods indicate that considering the dissolution rate and corrosion inhibiting rate comprehensively ,the water soluble extracting effect at 80℃is better than that of alcohol or acid extractant. When the dosage of extracted solution is 7.52 ×10-3 g/mL,the corrosion inhibiting rate for steel Q235 can reach 92.1%and corrosion rate can be reduced to 0.043 0 mm/a. The corrosion inhibition is of anodic type.
