Chemical composition and herbicidal, antifungal, antibacterial and molluscicidal activities of essential oils from Choukzerk, , and Alexander, , from western Algeria were characterized. Capillary GC-FID and GC/MS were used to investigate chemical composition of both essential oils, and the antifungal, antibacterial, molluscicidal and herbicidal activities were determined by % inhibition. Collective essential oil of was dominated by falcarinol (74.8%) and octane (5.6%). The collective essential oil of was dominated by furanoeremophilone (31.5%), furanodiene+curzurene (19.3%) and (E)-β-caryophyllene (11%). The oil was tested and a pure falcarinol (99%) showed virtuous herbicidal and antibacterial activities against potato blackleg disease, , and Gram-negative soil bacterium, (85 and 100% inhibition, respectively), and high ecotoxic activity against brine shrimp, , and the freshwater snail, , with an IC of 0.35 µg/mL and 0.61 µg/mL, respectively. Essential oil of showed interesting antibacterial and ecotoxic activity and good herbicidal activity against watercress seeds, (74% inhibition of photosynthesis, 80% mortality on growth test on model watercress), while the furanoeremophilone isolated from the oil (99% pure) showed moderate herbicidal activity. Both oils showed excellent antifungal activity against . Both oils and especially falcarinol demonstrated good potential as new biocontrol agents in organic crop protection.
对来自阿尔及利亚西部的Choukzerk和Alexander的精油的化学成分以及除草、抗真菌、抗菌和杀软体动物活性进行了表征。采用毛细管气相色谱 - 火焰离子化检测器（GC - FID）和气相色谱 - 质谱联用仪（GC/MS）研究两种精油的化学成分，并通过抑制率测定抗真菌、抗菌、杀软体动物和除草活性。Choukzerk的混合精油以镰叶芹醇（74.8%）和辛烷（5.6%）为主。Alexander的混合精油以呋喃艾里莫芬酮（31.5%）、呋喃二烯 + 莪术烯（19.3%）和（E）-β-石竹烯（11%）为主。对Choukzerk精油进行了测试，纯度为99%的纯镰叶芹醇对马铃薯黑胫病病原菌和革兰氏阴性土壤细菌表现出良好的除草和抗菌活性（抑制率分别为85%和100%），对卤虫和淡水螺具有高生态毒性活性，IC50分别为0.35 µg/mL和0.61 µg/mL。Alexander精油表现出有趣的抗菌和生态毒性活性以及对豆瓣菜种子良好的除草活性（光合作用抑制率74%，在模式豆瓣菜生长试验中死亡率80%）），而从该精油中分离出的呋喃艾里莫芬酮（纯度99%）表现出中等除草活性。两种精油对[具体真菌名称未给出]均表现出优异的抗真菌活性。两种精油尤其是镰叶芹醇在有机作物保护中作为新型生物防治剂具有良好的潜力。
