Embodiment 1

[0033] Such as figure 2 As shown, Step A: Dissolve the alkaloid extract extracted from Jatropha Jatropha leaves in dichloromethane at 25°C, and use n-octane / ethyl acetate (volume ratio 3:1) in a 400-mesh chromatography silica gel column The mixed solvent was rinsed for 15 h, and the eluent was rotary evaporated to obtain N-substituted phenylacetamide. Add 20.5Kg of the alkaloid extract N-substituted phenylacetamide extracted from Jatropha jatropha branches to 15.6Kg of vegetable oil squeezed from the Jatropha seed kernel, stir at 20°C for 10min to dissolve the alkaloid extract and obtain a uniform The oil phase mixture a, stirring speed 3000r / min.

[0034] Step B: Add 5Kg of surfactant sodium dodecylbenzenesulfonate and 0.5Kg of co-surfactant lauryl alcohol into the above-mentioned phase oil mixture a, stir at 3000r / min for 5min to obtain a homogeneous oil phase mixture b.

[0035] Step C: 58.4Kg of water is gradually added to the above-mentioned uniform oil phase mixture b...

Embodiment 2

[0038]Step A: Dissolve the alkaloid extract mixture extracted from Jatropha Jatropha leaves in dichloromethane at 28°C, and use a mixed solvent of ether / cyclohexane (volume ratio 2:1) in a 300-mesh chromatography silica gel column Rinse for 30 h, and then evaporate the eluent by rotary evaporation to obtain 6-diethylaminobenzofuran-3-one. Add 30.2Kg of the alkaloid extract 6-diethylaminobenzofuran-3-one extracted from the branches of Jatropha Jatropha to 27.3Kg of vegetable oil squeezed from Jatropha Jatropha seeds, and stir at 24°C for 15 minutes to extract the alkaloids The substance is dissolved and a homogeneous oil phase mixture a is obtained, and the stirring speed is 4000r / min.

[0039] Step B: Add 10Kg of surfactant polyvinylpyrrolidone and 2Kg of co-surfactant ethylene glycol into the above-mentioned phase oil mixture a, stir at 4000r / min for 7min to obtain a homogeneous oil phase mixture b.

[0040] Step C: 30.2Kg of water is gradually added to the above-mentioned u...

Embodiment 3

[0043] Step A: Dissolve the alkaloid extract mixture extracted from Jatropha Jatropha leaves in chloroform at 40°C, and use a mixed solvent of tetrahydrofuran / cyclohexane (volume ratio 2:1) in a 300-mesh chromatography silica gel column Rinse for 36 hours, and then rotate the eluate to obtain tetrahydroisoquinoline derivatives. Add 25.0Kg of the alkaloid extract tetrahydroisoquinoline derivatives extracted from Jatropha Jatropha branches to 34.2Kg of vegetable oil squeezed from Jatropha Jatropha seeds, stir at 25°C for 18 minutes to dissolve the alkaloid extract and obtain a uniform The oil phase mixture a, stirring speed 4500r / min.

[0044] Step B: Add 8Kg of surfactant polyvinyl alcohol and 1Kg of co-surfactant polyethylene glycol into the above phase oil mixture a, stir at 4500r / min for 8min to obtain a homogeneous oil phase mixture b.

[0045] Step C: 31.8Kg of water was gradually added to the above-mentioned uniform oil phase mixture b, and then stirred at a high speed o...

Abstract

The invention provides a jatropha curcas source environment disinfectant and a preparation method thereof, and belongs to the technical field of biotechnology, wherein the jatropha curcas source environment disinfectant is prepared from the following raw materials by weight: 20.5-30.2% of a jatropha curcas trunk alkaloid extract, 15.6-34.2% of vegetable oil, 30.5-58.4% of water, 5-10% of a surfactant and 0.5-2% of a cosurfactant. The preparation method comprises: A, adding 1-20% by weight of a jatropha curcas trunk alkaloid extract into 5-20% by weight of vegetable oil, and stirring at 20-28 DEG C to dissolve the jatropha curcas trunk alkaloid extract so as to obtain a uniform oil-phase mixture a; B, adding 1-20% by weight of a surfactant and 1-5% by weight of a cosurfactant into the oil-phase mixture a, and stirring to obtain a uniform oil-phase mixture b; and C, gradually adding 40-90% by weight of water into the uniform oil-phase mixture b, and then stirring at a high speed of 10000-15000 r / min for 20-30 min to obtain the oil-in-water type micro-emulsion.

Description

technical field [0001] The invention belongs to the technical field of biotechnology, and in particular relates to a jatropha source environmental disinfectant and a preparation method thereof. Background technique [0002] Phytopathogenic fungi will cause huge losses to my country's agricultural production every year, but the domestic and foreign crop fungicide markets are still dominated by chemical agents. Although chemical agents can effectively kill pests, the inherent toxicity of chemical components and unreasonable long-term abuse by people not only lead to serious chemical residues, drug resistance and problems, but also destroy the ecological balance of nature, and are harmful to human health. It has caused great harm, not only is not conducive to the export of agricultural products, but also does not meet the long-term goal of sustainable development of our country. Therefore, it is a current research hotspot to find new natural substances with high efficiency, lo...
