侧柏叶对烟草仓储害虫烟草甲和赤拟谷盗的毒杀作用 总被引:1,自引:0,他引:1
为有效防治烟草仓储害虫,进行了新型植物防护剂的开发研究。通过熏蒸和触杀试验测试了侧柏叶挥发油及单体成分活性,并通过GC/MS分析了侧柏叶挥发油的化学成分。结果显示:①GC/MS分析共鉴定出侧柏叶挥发油成分34种,占总成分的93.28%,其主要成分为:α-蒎烯(15.08%)、雪松醇(12.63%)、3-蒈烯(9.68%)和石竹烯(9.02%)。②通过生物活性筛选,侧柏叶挥发油对烟草甲和赤拟谷盗触杀的半数致死量分别为50.45和48.59μg/头;对二者熏蒸活性的半数致死浓度为145.40和39.25 mg/L。③从侧柏叶挥发油中得到3种活性成分:α-蒎烯、β-水芹烯和4-萜烯醇。因此,侧柏叶挥发油及其活性单体对烟草甲和赤拟谷盗均具有一定的触杀和熏蒸活性。 相似文献

Lamiaceae is among the largest families of flowering plants with about 250 genera and over 7,000 species distributed around the world. It is considered as the important source of essential oils, for example, menthol, geraniol, eucalyptol, camphor and thymol. Therefore, it is imperative to study these economically important compounds under in vitro conditions for their sustainable and enhanced production. In addition to proven biological activities, essential oils from this family have recently been evaluated for anticancer activities and considered as a source of anticancer drugs. Mechanisms involved in the essential oils-mediated antiproliferative activity include cell cycle arrest, apoptosis and DNA repair mechanisms. Essential oils also act in the reduction of tumors, inhibiting metastasis and as anti-multidrug resistance molecules. The aim of this review is to assess the anticancer properties of essential oils obtained from different members of family Lamiaceae. The available reports on active components of essential oils and their effect on cancer type and cell line have been discussed. Biotechnological studies to improve the production of essential oils have also been highlighted. Various methods have been adopted to obtain essential oils under in vitro conditions from different plant species of family Lamiaceae, and their production is affected by culture conditions, cultivation mode, utilization of nutrient media and plant growth regulators. The literature survey suggests that essential oils obtained from family Lamiaceae have perspective for the development of new alternatives for disease treatment and prevention. 相似文献

Essential oils are concentrated liquids of complex mixtures of volatile compounds and can be extracted from several plant organs. Essential oils are a good source of several bioactive compounds, which possess antioxidative and antimicrobial properties. In addition, some essential oils have been used as medicine. Furthermore, the uses of essential oils have received increasing attention as the natural additives for the shelf‐life extension of food products, due to the risk in using synthetic preservatives. Essential oils can be incorporated into packaging, in which they can provide multifunctions termed “active or smart packaging.” Those essential oils are able to modify the matrix of packaging materials, thereby rendering the improved properties. This review covers up‐to‐date literatures on essential oils including sources, chemical composition, extraction methods, bioactivities, and their applications, particularly with the emphasis on preservation and the shelf‐life extension of food products. 相似文献

通过水蒸气蒸馏法提取了花椒、柠檬、脐橙、蜜柚、砂糖橘、丑柑以及椪柑7种芸香科植物的挥发性成分。采用肉汤稀释法测定了上述7种单种精油以及2组复配精油对金黄色葡萄球菌、表皮葡萄球菌、白色葡萄球菌、枯草芽孢杆菌等6种常见致病细菌的抑菌活性。结果表明,7种芸香科精油对金黄色葡萄球菌、表皮葡萄球菌、白色葡萄球菌、大肠杆菌、伤寒杆菌和枯草芽孢杆菌的生长均表现不同程度的抑制活性。除了丑柑精油外,其余6种精油对大肠杆菌均表现出了杀灭活性,MBC值在20~40mg/mL之间。精油按照不同比例复配后,抑制活性表现出差异性,柠檬与蜜柚或花椒精油存在拮抗作用。研究结果有助于了解单种精油和复方精油的抑菌性能,为芸香科植物精油的开发应用提供依据。 相似文献
