摘要

The essential oils from the flower, leaf, and stem of Echinophora lamondiana B. Yildiz et Z. Bahcecioglu were analyzed by gas chromatography-flame ionization detection and gas chromatography-mass spectrometry. In total, 41, 37, and 44 compounds were identified, which accounted for 98.0, 99.1, and 97.0% of flower, leaf, and stem essential oils, respectively. The monoterpenic hydrocarbons were found to be high in all samples of the essential oils. The major components of essential oils from flower, leaf, and stem of Echinophora lamondiana were delta-3-carene (61.9, 75.0, and 65.9%, respectively), alpha-phellandrene (20.3, 14.1, and 12.8%, respectively), and terpinolene (2.7, 3.3, and 2.9%, respectively). Flower and leaf essential oils and terpinolene produced biting deterrence similar to 25 nmol/cm(2) N, N-diethyl-meta-toluamide (DEET; 97%) against Aedes aegypti (L.) and Anopheles quadrimaculatus Say. Compounds (+)-delta-3-carene, (R)-(-)-alpha-phellandrene, and water-distilled essential oils were significantly less repellent than DEET. Among essential oils, leaf oil was the least toxic of the oils, with an LC50 value of 138.3 ppm, whereas flower essential oil killed only 32% larvae, and no mortality of stem oil at highest tested dosages against Ae aegypti was observed. Terpinolene and alpha-phellandrene showed higher toxicity than delta-3-carene in both the species. In contrast to Ae. aegypti, all the essential oils showed toxicity in An. quadrimaculatus, and toxicity was higher in leaf oil than the other two oils. These results could be useful in finding new, safe, and more effective natural biopesticides and biting deterrent or repellents against Ae. aegypti.

Bahcecioglu的花，叶和茎中的精油。总共鉴定出41、37和44种化合物，分别占花，叶和茎精油的98.0％，99.1和97.0％。发现所有精油样品中的单萜烃含量都很高。刺chin的花，叶和茎的香精油的主要成分是delta-3-carene（分别为61.9％，75.0和65.9％），α-phlandlandrene（分别为20.3、14.1和12.8％）和萜品油烯（分别为2.7％，3.3％和2.9％）。花和叶的香精油和萜品油烯对埃及伊蚊（L.）和按蚊Anopheles quadrimaculatus说的类似于25 nmol / cm（2）N，N-二乙基-间甲酰胺（DEET; 97％）的咬制威慑作用。化合物（+）-δ-3-碳烯，（R）-（-）-α-水芹烯和水蒸馏精油的驱避性明显低于DEET。在精油中，叶油是这些油中毒性最低的，LC50值为138.3 ppm，而花精油仅杀死32％的幼虫，并且在最高测试剂量下对埃及伊蚊没有观察到茎油的死亡率。在这两个物种中，萜品油烯和α-芹烯烯的毒性均高于δ3-胡萝卜素。与Ae相反。埃及，所有精油在An中均显示出毒性。豆油，其毒性比其他两种油更高。这些结果可能有助于发现新的，安全的和更有效的天然生物杀虫剂，以及对Ae产生刺激性的阻吓剂或驱避剂。埃及。
