Embodiment 1

[0017] The technical scheme that present embodiment 1 adopts is as follows:

[0018] The sustained-release preparation of camellia green tea extract consists of the following raw materials by weight percentage: 45% camellia green tea extract, 25% hydroxypropyl methylcellulose k100m25%, 25% diluent, 4% microcrystalline cellulose, stearic acid Magnesium 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, and compres...

Embodiment 2

[0021] The difference from Example 1 is that carboxymethyl cellulose (CMC) is selected as the skeleton material.

Embodiment 3

[0023] The difference from Example 1 is that polyvinylpyrrolidone (PVP) is selected as the skeleton material.

Abstract

The invention discloses a slow-release preparation of a Hainan holly leaf extract and a preparation method of the preparation. The slow-release preparation of the Hainan holly leaf extract is prepared from the following raw materials by mass percent: 4-65% of Hainan holly leaf extract, 25-50% of framework material, 15-50% of diluent, 1-4% of filling agent, and 1% of lubricant. The method for preparing the slow-release preparation of the hainan holly leaf extract comprises the following steps: taking the raw materials according to the proportion; respectively screening by a 100mesh sieve, fully and evenly mixing; preparing a soft material by 60-80% ethanol; screening by a 10-30mesh sieve, and pelletizing; baking at 60-80 DEG C; straightening; adding 1% of magnesium stearate to evenly mix; and adjusting a tablet press to tablet, so as to prepare the slow-release preparation. The slow-release preparation prepared by the method is longer in pharmacologic action lasting time than a common hypotensive capsule and has a remarkable antihypertensive effect, the medicines in the preparation are slowly released at a non-constant speed, the administration frequency is obviously reduced, and the slow-release preparation is the slow-release preparation with significant curative effects.
