Abstract

The invention provides plant miticide prepared by taking scopoletin lactone as the main raw material and then adding in solvent, solubilizer and / or emulsifier, is environmental-friendly harmonious pesticide which is safety to human beings and animals, and has profound significance in the long-termed development of the ecological environment, the health of human beings and the integrated control of diseases. Compared with traditional pesticide, the scopoletin lactone plant miticide is characterized in and has the advantages that: 1. the scopoletin lactone exists in nature is a large amount, has low toxicity, is easy to degrade and is safety to the ecological environment; 2. the scopoletin lactone extraction method is simpler; 3. the scopoletin lactone can be also synthesized manually, has low cost and is easily applied to industrial large-scale production; 4. the scopoletin lactone can be solved in various solvent, is easy to be mixed with other anti-mite components to prepare medicine, and can play the role of improving the anti-mite effect; and 5. the scopoletin lactone can inhibit cellular signal transduction, is good neuromuscular blocking agent, and can quickly palsies harmful mites.

Description

technical field [0001] The invention relates to a scopoletin plant acaricide and a new application of the scopoletin. Background technique [0002] Scopoletine, also known as scopoletin, scopoletin, scopoletin, scopoletin, scopolamine, 7-hydroxy-6-methoxycoumarin, 7-hydroxy-6-methyl Oxy-2H-1-benzopyran-2-one; molecular formula: C 10 h 8 o 4 , molecular weight: 192.17; needle-like or prismatic crystals; can reduce Fehling's solution; soluble in xylene, hot ethanol or hot glacial acetic acid, slightly soluble in chloroform, water or cold ethanol, almost insoluble in benzene; its ethanol solution Blue fluorescence, melting point 204 ℃; maximum absorption wavelength 230, 254, 260, 298, 346nm; irritating. Scopoletin belongs to the coumarin compounds and is often used as an analgesic, anti-inflammatory, blood pressure-lowering and muscle spasm relieving drug. However, there is no report on the application of scopoletin in the preparation of plant-derived acaricides in the exi...
