摘　　要：采用溶剂提取结合水蒸气蒸馏法分离不同季节抗虫马尾松针叶化学成分,测定其化学成分相对含量并鉴定结构,分析抗虫马尾松不同季节针叶化学成分的变化。结果表明:从抗虫马尾松针叶中分离得到化合物74种,鉴定出45种,主要是单萜烯,倍半萜烯和醇类等物质;不同季节间针叶化学成分相对含量存在较大差异;化学成分随季节变化呈现不同的变化趋势;不同的单萜烯类化合物含量变化显著正相关,单萜烯总含量变化与倍半萜烯总含量呈显著负相关关系。The chemical compositions were separated from needles of insect-resistant clones of Pinus masso- nania by solvent extraction combined with steam-distillation. Relative content and structure of the chemical compo- sitions were analyzed and identified. The results showed that 74 components were detected, of which 45 were identi- fied. Major compositions were monoterpenes, sesquiterpenes and alcohols. There were significant differences in the relative contents of the chemical compositions in different seasons. The chemical composition changeed with the sea- sons showed different trends. Contents of monoterpenes variation showed significant and positive correlation with each other. Monoterpenes contents variation showed significantly negative correlation relationship with sesquiterpenes.
