在研究具有抗昆虫生物活性的植物次生代谢产物过程中,对从海南三七Kaempferia rotunda L.分得的8个化合物进行了结构鉴定,并对海灰翅夜蛾进行了拒食实验。将冷冻、干燥且粉碎的海南三七用甲醇在室温下提取24 h,提取物过滤、真空浓缩后溶于甲醇,混合液经分析型HPLC分离、检测,检测到8个主要成 In the process of studying the secondary metabolites of plants with biological activities against insects, eight compounds from Kaempferia rotunda L. of Hainan Sanqi were identified and the antifeeding test of Spodoptera littoralis was carried out. The frozen, dried and comminuted Hainan Sanqi was extracted with methanol at room temperature for 24 h. The extract was filtered, concentrated in vacuo and dissolved in methanol. The mixture was separated and analyzed by analytical HPLC. Eight major components were detected.
