Embodiment 1
[0021] After the broccoli seeds are fully crushed, pass through a 20-mesh sieve, add 30 times the weight of distilled water for hydrolysis; after filtration, the slag is fully washed with water and centrifuged; the hydrolyzate is degreased with excess n-hexane; the degreased hydrolyzate is added with ethanol (0.2ml ethanol / 1ml hydrolyzate) to inactivate myrosinase, and the hydrolyzate was concentrated in a water bath (70° C.) to obtain broccoli seed extract.
[0022] Adding auxiliary materials such as starch, sucrose, dextrin, glucose, calcium sulfate and microcrystalline cellulose to the obtained broccoli seed extract, adjusting the pH to 3.5, drying into powder, and pressing into tablets.
Embodiment 2
[0024] After the broccoli seeds are fully crushed, pass through a 20-mesh sieve, add 10 times the weight of deionized water for hydrolysis; after centrifugation, the slag is fully washed with water and filtered; the hydrolyzate is degreased with excess petroleum ether; the degreased hydrolyzate is added with ethanol (0.04ml ethanol / 1ml hydrolyzate) inactivated myrosinase, and the hydrolyzate was concentrated in a water bath (60° C.) to obtain broccoli seed extract.
[0025] Adding auxiliary materials such as starch, sucrose, dextrin, glucose, calcium sulfate and microcrystalline cellulose to the obtained broccoli seed extract, adjusting the pH to 3.5, drying into powder, and pressing into tablets.
Embodiment 3
[0027] After the broccoli seeds are fully crushed, pass through a 20-mesh sieve, add 60 times the weight of distilled water for hydrolysis; after centrifugation, the slag is fully washed with water and centrifuged; the hydrolyzate is degreased with excess n-hexane; the hydrolyzate after degreasing is added with ethanol (1ml ethanol / 1ml hydrolyzate) to inactivate myrosinase, and the hydrolyzate was concentrated in a water bath (100° C.) to obtain broccoli seed extract.
[0028] Adding auxiliary materials such as starch, sucrose, dextrin, glucose, calcium sulfate and microcrystalline cellulose to the obtained broccoli seed extract, adjusting the pH to 3.5, drying into powder, and pressing into tablets.
