[0027] In an embodiment, the preparation method of the medicinal compound plant fatty acid zinc comprises the following steps:
[0028] S1: Pass nitrogen to the reaction kettle to exhaust oxygen, increase the nitrogen flow to 0.8-1.2L / min when exhausting oxygen, after the oxygen is exhausted, reduce the nitrogen flow to 0.1-0.2L / min, add 12- 18g of polyethylene glycol 200, 213-242g of linolenic acid, stirred and heated to 56-73°C at a rotation speed of 200-300r / min, to obtain a heated mixture A;
[0029] S2: Add 60-74g of zinc hydroxide powder to the mixture A prepared in step S1, and stir for 6-10min at a rotation speed of 300-400r / min to prepare a mixture B;
[0030] S3: Heat the mixture B prepared in step S2 to 110-116°C at a microwave power of 300-400W, add 22-25g of water and 10-15g of propionic anhydride, keep the microwave power and temperature constant, and increase the speed to 600 Stir the reaction at -800r / min for 25-35min to prepare the reactant;
[0031] S4: Fil...
