Abstract
Three dihydrochalcone compounds were isolated from the twigs of Stewartia koreana (Theaceae) through repeated column chromatography. Their chemical structures were elucidated as phloridizin, 2¡¯,4,4¡¯-trihydroxy-6¡¯-methoxydihydrochalcone and confusoside, respectively, by spectroscopic analysis. These compounds were isolated for the first time from this plant.
