The extract from the bark of Juglans mandshurica Maxim.was extracted again with chloroform or acetic ether.The active components in the chloroform part and the acetic ether part of the alcohol extract(separated with chloroform and acetic ether from the alcohol extract) were analyzed for by GC-MS.The major active components in the chloroform part of the alcohol extract from the bark might be 5-hydroxy-1,4-naphthalenedione(juglone,36.65%),4-hydroxy-2-methoxycinnamaldehyde,2,3-dihydro-benzofuran,vanillin,and 2-methoxy-4-vinylphenol.The major active components in the acetic ether part of the alcohol extract from the bark of Juglans mandshurica might be 1,2,3-benzenetriol(42.31%),juglone(12.33%),7-methoxy-1-tetralone(11.26%),5-(hydroxymethyl)-2-furancarboxaldehyde,3,4-dihydro-6,7-dihydroxy-1(2H)-naphthalenone,4-hydroxy-2-methoxycinnamaldehyde,and D-allose.
