Seven compounds were isolated from the n-BuOH extract of the dried stem barks of Rhus javanica L. On the basis of physico-chemical, spectroscopic evidences and comparison with authentic samples, the compounds $1{\sim}7$ were identified as gallic acid (1), methyl gallate (2), scopoletin (3), scopolin (4), $1,\;2,\;3,\;4,\;6-penta-O-galloyl-{\beta}-D-glucose$ (5), orcinol (6) and $orcinol-{\beta}-D-glucoside$ (7). Among these compounds, scopolin, $orcinol-{\beta}-D-glucoside$ were isolated from this plant for the first time.
