摘 要 ：采用GC/M S联用技术,对杠柳根皮中挥发油的化学成分进行了分析,共分离出15种化合物,对其中10种进行了鉴定,已鉴定成分占挥发油总成分的94.91%,分别为4-甲氧基水杨醛、乙酸丁酯、2-甲基-1,3-二氧环戊基乙酸乙酯、乙羟硫代羧酸-8-二乙氧基磷酰正辛酯、1,1,3,3-四丁氧基-2-丙酮、4-甲基-2-戊酮、甲酸丁酯、1-(1-乙氧基乙氧基)丁烷、2-正丁氧基四氢吡喃及丁醚。以麦二叉蚜为试虫进行挥发油杀虫活性测定。结果表明,杠柳根皮挥发油对试虫具有较强的触杀活性。

Abstract:Chemical components of essential oil in Periploca sepium root bark were determined by gas chromatography-mass spectrometer and thus 15 compounds were isolated;then ten of the compounds were identified to be 4-methoxysalicylaldehyde,butyl acetate,2-methyl-
