| titleOfInvention | A kind of paulownia dregs of rice method for producing insecticide |
| abstract | A kind of paulownia dregs of rice method for producing insecticide, comprises the following steps：（1）After the paulownia dregs of rice are dried, crushed through pulverizer, the mesh sieve of mistake >=50, to ethanol heating and refluxing extraction that sieving volume fraction is 60~95% 2~4 times, carry out vacuum distillation recycling ethanol after merging extracting solution, obtain alcohol extracting thing medicinal extract；（2）Into alcohol extracting thing medicinal extract plus water mixes；（3）Ethyl acetate is added into alcohol extracting thing aqueous solution, stirring 10~30 minutes, then it is layered after when standing extraction 13 is small, take upper strata aqueous phase to carry out vacuum distillation recycling ethyl acetate, obtain upper strata concentrate, extract 2~4 times repeatedly, after merging upper strata concentrate, carry out vacuum distillation and remove remaining ethyl acetate, obtain paulownia dregs of rice extract medicinal extract, be paulownia dregs of rice extract insecticide.Using the present invention, paulownia dregs of rice resource can be fully developed and utilized, by the way that the paulownia dregs of rice are made vegetable insecticide, tung oil tree paulownia dregs of rice added value can be improved. |
