Abstract: PURPOSE: A novel herbicidal material, angelicin, isolated from Rumex crispus L. and a method for isolating the same are provided to ensure unique chemical structure and to develop novel herbicide. CONSTITUTION: An herbicide composition contains angelicin or agriculturally acceptable salt thereof as an active ingredient. Angelicin is isolated from Rumex crispus L. A method for isolating angelicin from Rumex crispus L. comprises: a step of extracting Rumex crispus L. with methanol; a step of dissolving methanol extract with ethyl acetate to obtain an ethyl acetate fraction; a step of obtaining a fraction(EC) of herbicidal activity from ethyl acetate fraction using dichloromethane-methanol solution; a step of obtaining a fraction(ECD) from the fraction(EC) using ethylacetate-dichloromethane-methanol solution; a step of obtaining a fraction(ECDA) from the fraction(ECD) using hexane-ethyl acetate-dichloromethane-methanol solution; and a step of identifying the structure of the fraction(ECDA).
