采用气相色谱-质谱联用技术对杠柳根皮挥发油的化学成分进行了分析，分离得到15个化合物;其中10个化合物分别鉴定为4-甲氧基水杨醛、乙酸丁酯、2-甲基-1，3-二氧基-环戊基乙酸酯、S-[8-（4-甲氧基苯基）-2-甲基-苯并咪唑]-乙酸酯、4-甲氧基水杨醛、乙酸丁酯、乙酸乙酯（二乙基膦酰基）辛基]硫代乙酸酯、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，和2-丁氧基四氢吡喃，丁基醚，占（94.91%）用二叉蚜（Schizaphis graminum）进行杀虫活性测定，结果表明，该挥发油具有较强的杀虫活性测试昆虫的活动。
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-1,3-dioxy-cyclopentyl acetate,S-[8-(diethylphosphono)octyl] ethanethioate,1,1,3,3,-tetrabutoxy-2-propanone,4-methyl-2-pentanone,butyl formate,1-(1-ethoxyethoxy)-butane,and 2-butoxyretrahydropyran,butyl ether,which accounted for(94.91%) of the essential oil.The insecticidal activity of the essential oil was tested with Schizaphis graminum and the test results indicated that the essential oil had strong insecticidal activity to the test insect.
