NOVELTY - Preparing Vernicia shell extract pesticide, comprises e.g. drying the Vernicia shell, grinding, sieving, heating, backflow extracting, combining extracts, reduced pressure distillating, adding water and chloroform, stirring, stewing, layering, taking the lower aqueous phase, recycling the chloroform, collecting upper aqueous phase, extracting, combining each extracted upper aqueous phase, adding ethyl acetate, stewing, layering, taking the upper aqueous phase, recycling the ethyl acetate, extracting, combining each extracted upper concentrated liquid and distilling.    USE - The method is useful for preparing Vernicia shell extract pesticide.    ADVANTAGE - The method is capable of simply, easily and economically preparing Vernicia shell extract pesticide with high efficiency, low toxicity, high yield and reduced material consumption and without environmental pollution.    DETAILED DESCRIPTION - Preparing Vernicia shell extract pesticide, comprises drying the Vernicia shell in sun, grinding with a grinder, passing through less than 50 meshes sieve, heating to 90-100 degrees C with 60-95% ethanol, backflow extracting for 1-3 times, where the ratio of the added volume of ethanol for each time to the mass of sifting material is 4-7:1 and each extraction time is 3-5 hours, combining each extract, reduced pressure distillating with a rotary evaporator to recycle the ethanol until the ethanol volatilizing thoroughly, obtaining the ethanol extract, adding water into the ethanol extract and mixing uniformly, where the ratio of the added volume of water to the mass of the ethanol extract is 0.8-1.2:1, adding chloroform into the ethanol extract aqueous solution, where the added volume of the chloroform to the volume of the ethanol extract aqueous solution is 0.8-1.2:1, stirring for 10-30 minutes, stewing extracting for 1-3 hours, layering, taking the lower aqueous phase for reduced pressure distillation, recycling the chloroform, collecting upper aqueous phase, repeatedly extracting for 2-4 times, combining each extracted upper aqueous phase, adding ethyl acetate into the upper aqueous phase combined liquid, where the added volume of the ethyl acetate to the volume of the upper aqueous phase combined liquid is 1-3:1, stirring for 10-30 minutes, stewing extracting for 1-2 hours, layering, taking the upper aqueous phase for reduced pressure distillation, recycling the ethyl acetate, obtaining the upper concentrated liquid, repeatedly extracting for 2-4 times, combining each extracted upper concentrated liquid, and reduced pressure distillating to remove the residual ethyl acetate to obtain the product.
