摘要：

To provide a method for producing an extract of Macaranga tanarium and with which an extract of Macaranga tanarium containing a useful component derived from Macaranga tanarium in a high concentration is readily produced.

SOLUTION: The extract of Macaranga tanarium is produced by extracting Macaranga tanarium with water to give a solid component and then extracting the solid component with an organic solvent. Water at &ge 90° C is preferably used in the water extraction. An extraction solvent comprising a lower alcohol as a main component is preferably used in the organic solvent extraction. The extract of Macaranga tanarium contains nymphaeol B and C, preferably contains nymphaeol A and/or propolin A besides nymphaeol B and C. The figure (a) shows chromatogram obtained by HPLC analysis of a water extracted solution by extraction of leaves of Macaranga tanarium with water and the figure (b) shows chromatogram obtained by HPLC analysis of a primary extract obtained by organic solvent extraction of the solid component with ethanol after the water extraction and the figure (c) shows chromatogram obtained by HPLC analysis of a secondary extract obtained by further organic solvent extraction of the primary extract with ethanol.
