摘　　要：采用常规提取法浸提核桃楸树皮的活性成分,采用GC-MS联用技术对核桃楸树皮乙醇提取物中氯仿萃取物和乙酸乙酯萃取物的化学组成和各成分进行分析。结果表明,核桃楸树皮乙醇提取物中氯仿萃取物的主要活性成分分别为:5-羟基-1,4-萘醌(胡桃醌,质量分数36.65%),4-羟基-2-甲氧基肉桂醛,2,3-二氢苯并呋喃,香草醛,2-甲氧基-4-乙烯基苯酚。核桃楸树皮乙醇提取物中乙酸乙酯萃取物的主要活性成分分别为:1,2,3-苯三醇(质量分数42.31%),5-羟基-1,4-萘醌(胡桃醌,质量分数12.33%),7-甲氧基-1-四氢萘酮(质量分数11.26%),5-羟甲基-2-呋喃醛,3,4-二氢-6,7-二羟基-1(2H)-萘酮,4-羟基-2-甲氧基肉桂醛,D-阿洛糖。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.
