摘　　要：采用常规提取法浸提核桃楸外果皮的化感作用成分。研究结果表明,核桃楸外果皮乙醇提取物和乙酸乙酯萃取相对3种受体植物青菜、萝卜和紫花苜蓿具有化感作用(抑制萌发和抑制生长作用)。化感作用随提取物浓度增大而增大。采用GC-MS分析核桃楸外果皮乙醇提取物中乙酸乙酯萃取相的化学组成和相对含量。分析结果表明,核桃楸外果皮乙醇提取物中乙酸乙酯萃取相的主要化学成分为5-羟基-1,4-萘醌(胡桃醌),GC含量31.20%;正十六酸,GC含量9.99%;7-甲氧基-1-四氢萘酮,GC含量7.99%;1,5-萘二酚,GC含量7.15%;2,6-二甲氧基苯酚,GC含量4.36%;4-丁氧基苯醛;GC含量3.23%;5-羟甲基-2-呋喃醛,GC含量2.96%;二聚1,3-二羟基丙酮,GC含量2.94%;丙三醇,GC含量2.77%;1(3H)-异苯并呋喃酮,GC含量2.57%。The extract from green peel of Juglans mandshurica Maxim. was extracted by common method for studying its allelopathy and analyzing the chemical components. Results showed that the alcohol extract and the ethyl acetate part of alcohol extract （separated with ethyl acetate from alcohol extract） exhibit allelopathy （inhibiting seed germination and seedling growth ） on Brassica chinesis, Raphanus sativus and Medicago .sativa. Their effects were extract-concentration dependent, increasing with the increase of extract concentration. The chemical components in the ethyl acetate part of alcohol extract from green peel of J. mandshurica were analyzed by GC-MS. Results showed that the main chemical components and their GC contents in the ethyl acetate part of alcohol extract were： 5-hydroxy-1,4-naphthalenedione （juglone） 31.20 % , n-hexadeeanoie acid 9.99 % , 7-methoxy-l-tetralone 7.99 %, l, 5-naphthalenediol 7.15 % , 2, 6-dimethoxy-phenol 4.36 %, 4-butoxy benzaldehyde 3.23 % , 5-（hydroxymethyl） -2-furanearboxaldehyde 2.96 % , 1,3-dihydroxyaeetone dimmer 2.94 % ,glycerin 2.77 %, l （3H） - isobenzofuranone 2.57 %. Twenty-four compounds in the ethyl acetate part of alcohol extract have been identified with total GC content of 94.55 %.
