The application discloses a method for improving conversion rate of allyl isothiocyanate through enzymatic reaction, and the method comprises the following steps: firstly, extracting black mustard enzyme from broccoli seeds through ultrasonic extraction; secondly, flocculating the black mustard enzyme, alkyl glycoside and casein phosphopeptide under the action of sodium polyacrylate to form flocculation liquid, mixing the flocculation liquid with magnetic starch milk, and post-treating to obtain immobilized black mustard enzyme; and then, adding the immobilized black mustard enzyme into black mustard glycoside aqueous solution, and performing enzymolysis reaction under the condition of high-pressure pulse electric field to obtain allyl isothiocyanate. The application improves the conversion rate of allyl isothiocyanate through enzymatic reaction, and the product has high quality and wide application prospect.

The invention relates to the field of pest control, in particular to application and a method of allyl isothiocyanate in killing pine wood nematode disease on epidemic wood, and further, the epidemic wood is pine wood which is withered due to infection of the pine wood nematode disease. The allyl isothiocyanate recorded by the invention has a very strong fumigation effect on pine wood nematodes, can kill nematodes in infected withered and dead wood, and enables infected wood to be non-infected wood. Allyl isothiocyanate is a plant source component and is environmentally friendly, the medicament cost is very low, the medicament cost is 3 yuan or below per plant at the current market price, however, the retrieved pine value is 50-100 yuan or above per plant, and the popularization value is very high. Besides, the allyl isothiocyanate has extremely high volatility and can be quickly conducted in a withered pine trunk, generally, the allyl isothiocyanate can be conducted to all parts of the whole withered tree within about one month, and the problem that a common agent cannot be conducted in the withered tree is solved.

The invention belongs to the technical field of chemical synthesis, and particularly relates to a synthesis method of a self-foaming type sulfide ore flotation collecting agent. The synthesis method comprises the following steps: by taking allyl isothiocyanate and isooctyl alcohol polyoxyethylene ether as raw materials, under the action of an esterification catalyst, carrying out a heating reflux reaction, and removing unreacted isooctyl alcohol polyoxyethylene ether under reduced pressure, so as to prepare N-allyl-O-isooctyl polyoxyethylene ether-thionocarbamate; by adopting the high-boiling-point raw material, the problems of low conversion rate and high toxic raw material residue caused by limited reaction temperature in the traditional process are solved, and the obtained product is high in purity, has excellent collecting and foaming functions, is relatively long in hydrophobic chain, and can remarkably reduce the consumption of a foaming agent and the COD value of wastewater in the flotation process; the synthesis method provided by the invention has the advantages of simple process, controllable reaction, high safety and easiness in industrial production.

The present invention provides a composition having an action to enhance adrenomedullin gene expression. One or more embodiments of the present invention relate to a composition for enhancing adrenomedullin gene expression containing a TRPV1 agonist and a TRPA1 agonist as active ingredients. The TRPV1 agonist can be, for example, at least one selected from capsaicin, 6-shogaol, 6-gingerol and piperine. The TRPA1 agonist can be, for example, at least one selected from allyl isothiocyanate, cinnamaldehyde, diallyl disulfide, ASP7663 and oxylipin.

The application discloses a phyllotreta striolata attractant formed by diluting verbenone and / or verbenol in n-hexane to 10 mg / L-1000 mg / L. The application also discloses a phyllotreta striolata attractant comprising active components in the following weight parts: verbenone and / or verbenol 30-100 parts, butyl isothiocyanate 0-25 parts, allyl isothiocyanate 0-25 parts. The application further discloses a phyllotreta striolata lure core. The application provides the use of verbenone and verbenol as components of the phyllotreta striolata attractant, which has the characteristics of simple operation, convenient use, high attraction efficiency, etc.; the attraction rate of the phyllotreta striolata attractant to adult phyllotreta striolata is higher than 80%, the number of adult phyllotreta striolata in the field is significantly reduced, and the insect population density is reduced; the popularization of the application will significantly reduce the use of chemical pesticides, improve the problem of serious phyllotreta striolata damage, and improve the quality of cruciferous vegetables.
