Embodiment 1

[0080] The extraction method of active ingredient of the present invention

[0081] The plant material used for the production of the raw material in the present invention is Horseradish or Brassica Roots, stem parts, seeds, or oil-pressed cakes of plants. The extraction solvent is composed of acidic or neutral water or water plus one or more organic solvents, with a pH of 4-7.5; wherein the organic solvent is selected from one or more of acetic acid, acetone or ethyl acetate.

[0082] In the present invention, the extractant is selected from one or more of ether, ethyl acetate, dichloromethane, vegetable oil or petroleum ether.

[0083] Among them, the comminution of plant material:

[0084] horseradish Plant tissues such as roots and stems of plants belonging to the genus are washed, sliced, dried in the sun, crushed into powder by a hammer mill, passed through a 40-100 mesh sieve, and made into raw materials for future use. If it is extracted with seeds or cakes after...

Embodiment 2

[0098] Production of 20% allyl isothiocyanate oil agent for granary

[0099] Accurately and quantitatively weigh 190 kg of 96% AITC former drug, and then weigh 176 kg of extract mother liquor with 10% AITC content (which contains 1.90 kg of ascorbic acid). Put the two active ingredients liquid in 2m 3 Mix thoroughly in the mixing tank. Accurately take 10 kilograms of ascorbic acid again, drop in the deployment tank (1) and fully mix again. Then accurately drop 624 kilograms of rapeseed oil into the blending tank, and fully mix in the blending tank. Stirring was continued for 1 hour. Prepare 1 ton of AITC oil product. The content of AITC was sampled and analyzed, and the result was 20.01%. The product is divided into aluminum cans coated with barrier material, 5 kg per can, 200 cans in total. Seal the mouth of the jar and put a label on it to be a 20% AITC oil product.

Embodiment 3

[0101] The preparation process is the same as in Example 2, except that 1 ton of AITC oil contains 500 kilograms of the extracted mother liquor with an AITC content of 20%, 100 kilograms of xylene, 1 kilogram of amyl gallate, and 399 kilograms of crude soybean oil, and analyze the content of AITC therein 10%.
