Embodiment 1
[0022] Example 1, the Qiamagu glucosinolate extract is obtained according to the following preparation method: in the first step, the raw material Qiamagu is washed and pulverized, and then vacuum-dried to obtain dry Qiamagu, and 1 gram of dry Qiamagu Add 7ml to 11ml of methanol aqueous solution with a volume percentage of 80% to 100%, add methanol aqueous solution to the dried Chamagu, and perform one extraction in a constant temperature water bath at a temperature of 80°C for 0.5 hours to 1.5 hours. After the separation, the primary extract and the primary residue are obtained; the second step is to add an 80% to 100% methanol aqueous solution equal to the volume percentage of the first step to the primary residue, and place it in a constant temperature water bath at 80°C for 0.5 hours Carry out the secondary extraction for 1.5 hours, and obtain the secondary extraction solution and the secondary residue after the secondary extraction and separation; the third step, mix the...
Embodiment 2
[0023] Example 2, the Qiamagu glucosinolate extract is obtained according to the following preparation method: in the first step, the raw material Qiamagu is washed and pulverized, and then vacuum-dried to obtain dry Qiamagu, and 1 gram of dry Qiamagu Add 7 milliliters or 11 milliliters of 80% or 100% methanol aqueous solution to the dry Qiamagu, add methanol aqueous solution to the dry Qiamagu, and perform an extraction once in a constant temperature water bath at a temperature of 80 ° C for 0.5 hours or 1.5 hours. After the separation, the primary extract and the primary residue are obtained; in the second step, an 80% or 100% methanol aqueous solution equal to the volume percentage of the first step is added to the primary residue, and the temperature is 80°C in a constant temperature water bath for 0.5 hours Or carry out secondary extraction in 1.5 hours, obtain secondary extraction solution and secondary residue after secondary extraction and separation; third step, mix ...
Embodiment 3
[0024] Example 3, as an optimization of the above example, in the first step of Example 3, the raw material Qiamagu is crushed to a particle size of 50 mesh to 10 mesh, and then the pulverized raw material Qiamagu is placed at a temperature of 40 °C to 70 °C and vacuum drying at a pressure of -0.06Mpa to -0.09Mpa to obtain dry Chamagu with a mass percentage moisture content of less than or equal to 20%.
