采用气相色谱和气相色谱-质谱联用技术分析了我国柏科植物刺柏叶油、柏木油和柏木油的化学成分。我们确定了104种化合物，占66.895.5%的油。主要组成部分是：结果表明，在香柏中，α-松油烯（27.0%）、α-萜品烯（14.0%）和芳樟醇（10.9%）含量最高，在中华香柏中，α-雪松烯（16.9%）、雪松醇（7.6%）和β-雪松烯（5.7%）含量最高，分别为11.3%和7.8%。葬礼C.评价了非洲红毛蚊、中华红毛蚊和普通红毛蚊对成年黄热病蚊子、埃及伊蚊（Aedesaegypti（L.）孤星星蜱Amblyomma americanum（L.）和黑腿蜱，硬蜱肩胛说，并对Ae毒性。埃及伊蚊幼虫和成虫，都在实验室生物测定中。所有的油是排斥两种蜱。C. funebris、J. communis和J. chinensis对A.美国的分别为0.426，0.508和0.917毫克油/平方厘米滤纸相比，0.683毫克避蚊胺/平方厘米滤纸。所有我。0.103mg油/cm ~ 2滤纸片对肩胛突突刺线虫有驱避作用。葬礼油在施用后4 h，0.827mg油/cm 2滤纸、C.中华茉莉精油对A.美洲树C. funebris和J. chinensis对Ae.在最高测试剂量（1.500 mg/cm 2）下，埃及伊蚊叮咬。然而，J. communis的油具有0.029 +/- 0.018 mg/cm 2的驱避性的最小有效剂量（估计ED 99）;这种油几乎与避蚊胺一样有效。结果表明，核桃油对山羊草有一定的杀灭作用。埃及伊蚊幼虫，在125和250 ppm时分别为80%和100%。
Juniperus communis leaf oil, J. chinensis wood oil, and Cupressus funebris wood oil (Cupressaceae) from China were analyzed by gas chromatography and gas chromatography-mass spectrometry. We identified 104 compounds, representing 66.895.5% of the oils. The major components were: a-pinene (27.0%), a-terpinene (14.0%), and linalool (10.9%) for J. communis; cuparene (11.3%) and d-cadinene (7.8%) for J. chinensis; and a-cedrene (16.9%), cedrol (7.6%), and beta-cedrene (5.7%) for C. funebris. The essential oils of C. funebris, J. chinensis, and J. communis were evaluated for repellency against adult yellow fever mosquitoes, Aedes aegypti (L.), host-seeking nymphs of the lone star tick, Amblyomma americanum (L.), and the blacklegged tick, Ixodes scapularis Say, and for toxicity against Ae. aegypti larvae and adults, all in laboratory bioassays. All the oils were repellent to both species of ticks. The EC95 values of C. funebris, J. communis, and J. chinensis against A. americanum were 0.426, 0.508, and 0.917 mg oil/cm2 filter paper, respectively, compared to 0.683 mg deet/cm2 filter paper. All I. scapularis nymphs were repelled by 0.103 mg oil/cm2 filter paper of C. funebris oil. At 4 h after application, 0.827 mg oil/cm2 filter paper, C. funebris and J. chinensis oils repelled =80% of A. americanum nymphs. The oils of C. funebris and J. chinensis did not prevent female Ae. aegypti from biting at the highest dosage tested (1.500 mg/cm2). However, the oil of J. communis had a Minimum Effective Dosage (estimate of ED99) for repellency of 0.029 +/- 0.018 mg/cm2; this oil was nearly as potent as deet. The oil of J. chinensis showed a mild ability to kill Ae. aegypti larvae, at 80 and 100% at 125 and 250 ppm, respectively.
