农业植保
专门应用于植物源生物农药的活性成分
根据活性成分的种类,植物源生物农药(Plant Extracts Biopesticides)可大体分类为:生物碱类、挥发油(植物精油)类、光活化毒素类、黄酮类和萜烯类等。其中萜烯类天然成分一般在植物精油中含量最高,根据成分结构差异,进一步分为倍半萜烯、单萜、双萜和三萜。
萜烯类化合物可利用植物挥发物等活性物质成分,根据拒食、胃毒等作用机理干扰靶标昆虫的生殖、生理行为,从而起到植保的运用。可用作生物农药母药中的活性成分,开发拒食剂、引诱剂、趋避剂、除草剂等绿色生物农药。这类新农药具有无有害残留物、不污染土壤和水源,不毒害人体和动物等优势。且具备更强的IPM抗性管理能力,相比较传统化学农药,结构更复杂,靶标昆虫不易产生抗药性。
除此外,由于活性成分天然取源自植物本身,因此还具有增效功能,可起到植物增效剂、植物生长调节剂的功效。
Citral natural is a mixture of two geometric isomers,geranial (trans confirmation) and neral (cis confirmation).It is obtained by the vacuum distillation process of the lemon grass oil or litsea cubeba oil. Natural Anethole is mainly used as flavor in food, pharmaceutical, fragrance and industrial uses. Alpha- thujene is terpene fraction distilled from Eucalyptus. It appears colorless to pale yellow liquid with woody, green odor. 2-Phenylethanol is an antimicrobial, antiseptic, and disinfectant that is used also as an aromatic essence and preservative in pharmaceutics and perfumery. 甲基环戊烯(MCP)具有强烈的焦糖香气,可用于风味和甜味的增强。MCP可以提高人的味觉和嗅觉细胞对香气的敏感性,这就是所谓的美拉德效应。 因此,不仅MCP本身具有令人愉悦的甜味,而且对食品和烟草制品具有良好的增香效果。 松油醇是种单萜醇化合物,来源于α-蒎烯或松节油的水合反应。 其存在三种异构体:α-、β-和γ-松油醇。松油醇通常是这些异构体的混合物,主要成分为α-松油醇。在医用消毒领域,α-松油醇可用于消毒剂、杀菌产品等医用制剂中的杀菌成分。 对金黄色葡萄球菌、铜绿假单胞菌、大肠杆菌和白色念珠菌有显着作用。 据研究1,萜品醇MU在人体皮肤上停留2分钟,对皮肤表面天然细菌的平均杀灭率可达98.46%。Experi… Citronellyl acetate is industirally prepared by the esterification of Citronellol with Acetic Anhydride. It is extensively used in perfumery and fragrance. Carvone mainly used for the preparation of peppermint flavor of food and fragrance formulation of daily chemicals. Heliotropin is also known as piperonal, is widely used in the fragrance formulation of soaps, perfumes and cosmetics.
