Chemical Components from the Stem Bark of Cornus controversa $H_{EMSL}$

Cornus controversa $H_{EMSL}$. (Cornaceae) is distributed widely in Korea and has been used for the treatment of diarrhea and a tonic medicine. Six compounds were isolated from the MeOH extract of the dried stem bark of Cornus controversa. Their structures were identified as gallic acid(1), scopoletin(2), arjunglucoside II(3), isoquercitrin(4), quercitrin(5) and rutin(6) by comparisons of the physicochemical and spectroscopic evidences. Among these compounds, scopoletin and arjunglucoside II were the first time isolation from this plant.
