Abstract: PURPOSE: A new weeding active material 3-hydroxy-9H-xanthene-9-circle which is separated from sicyos angulatus and a separation method thereof are provided to be used as parent compound for herbicide which attacks new mode of action by having different structure from conventional herbicides. CONSTITUTION: A new weeding active material 3-hydroxy-9H-xanthene-9-circle which is separated from sicyos angulatus is separated from Sicyos angulatus L. The herbicide composition contains new compound having herbicidal activity. A separating method of new compound having herbicidal efficacy which is separated from the Sicyos angulatus comprises next steps: a step of extracting leaves or stems of the Sicyos angulatus; a step of obtaining dichloromethane fractions by dissolving methanol extract of the Sicyos angulatus in dichloromethane; a step of obtaining MD fractions which has Rf value of 0.37-0.00; a step of obtaining MDC fractions which has Rf value of 0.17-0.00; and a step of obtaining MDCC fractions which has Rf value of 0.70.
