To provide a biomaterial derived compound or a composition for prevention of disease injury caused by phytopathogenic fungi.
A method for production of a carbonic acid ester extract from angleworm fecal soil includes (A) a process to obtain a first aqueous phase by furnishing angleworm fecal soil to an aqueous extraction process, (B) a process to obtain an organic phase and a second aqueous phase by furnishing the first aqueous phase to an organic solvent extraction process, the solvent being other than carbonic acid ester shown by general formula (I), (C) a process to obtain a carbonic acid ester phase and a third aqueous phase by furnishing the second aqueous phase to an carbonic acid ester extraction process, the carbonic acid ester being shown by general formula (I): R-COOR' (wherein R represents a 1-8C alkyl group, R' represents a 1-4C alkyl group), and (D) a process to obtain a carbonic acid ester extract by removing the carbonic acid ester from the carbonic acid ester phase.
