摘要
目前已培育出的对云斑天牛有不同抗性的杨树品种中所含营养物质及次生代谢产物进行了初步分析,发现云斑天牛对杨树树干的危害与杨树中所含营养物质并无关系,而酚性化合物含量的多少是引起抗性的一个因素。另外,在硅甲基化的乙酸乙醇抽提物中,利用气质联用方法分析并确定苯酚等31个酚性化合物,其中4-羟基环己酮等化合物是首次在杨树品种中发现。同时,利用液相色谱,也分析确定了13个酚酸化合物。
This paper reports the chemical constituents resistant to Bactocera horsfieldi in different kinds of Populas deltoides. We discovered that the resistance of Popular deltoides was not related to nutritious substance but related to phenol componemts and tannin, 31 phenol constituents .were determined by GS/MS/DS. A few constituents are discovered in Populas deltoides. At times, 13constituents are also determined by HPLC.
