The result showed all the characteristic absorption peaks of hydroxyl-naphthaoquinone in the FT-IR spectrum of the product. The constituents of the product were determined by GC-MS to be: 1, 4-naphthaoquinone, 5-hydroxy-1,4-naphthaoquinone and 7-methoxy-1-tetralone, and the content of juglone in the product was 96.42%. The structure of juglone in the product was confirmed by 1H NMR. This study offered a simple and effective method to get high purity juglone from bark of J. mandshurica.
