Embodiment 1
[0017] The technical scheme that present embodiment 1 adopts is as follows:
[0018] The sustained-release preparation of camellia green tea extract is composed of the following raw materials by weight percentage: 45% of camellia green tea extract, 25% of hydroxypropyl methylcellulose k100m, 25% of diluent, 4% of microcrystalline cellulose, stearin Magnesium acid 1%; the diluent is made of lactose and compressible starch in a mass ratio of 4:3.
[0019] Weigh 157.5g of camellia extract, 87.5g of hydroxypropyl methylcellulose k100m, 50g of lactose, 37.5g of compressible starch, and 14g of microcrystalline cellulose, and pass through a 100-mesh sieve respectively. Mix evenly by the method of equal increments, add a certain amount of soft material made of 80% ethanol, pass through a 20-mesh sieve to granulate, dry at 80°C for 1 hour, pass through a 20-mesh sieve for finishing, and add 3.5g of magnesium stearate to the total amount of granules Mix evenly, adjust the tablet press,...
