Embodiment 1
[0019] The extract of Camellia japonica leaves is prepared by adding water to the leaves of Camellia japonica and then filtering, and the filter residue is also extracted by adding water three times, then filtering, combining the obtained filtrates, and drying under reduced pressure at 60°C to obtain the extract. The process of adding water to extract plant leaves and filter residues is as follows: add 20 times the weight of water each time, heat to boiling, then stop fire, heat soak for 100 minutes, heat again to boil, then stop fire, and heat soak for 100 minutes. The plant leaves are dry leaves, which are soaked in water for 120 minutes before being heated to boiling when adding water to extract. After inspection, the mass percentage of tea polyphenols, the signature component of the extract, is 15.5%. With the extract as an active ingredient, hard capsules are prepared according to conventional techniques in the art.
Embodiment 2
[0021] The extract of Camellia japonica leaves is prepared by adding water to the plant leaves of Camellia japonica and then filtering, and the filter residue is also extracted by adding water once and then filtered, and the obtained filtrates are combined and dried under reduced pressure at 60°C to obtain the extract. The process of adding water to extract plant leaves and filter residues is as follows: adding 30 times the weight of water each time, heating to boiling, then stopping the fire, soaking for 10 minutes, heating again to boiling, then stopping the fire, and soaking for 60 minutes. The plant leaves are dry leaves, which are soaked in water for 600 minutes before being heated to boiling when adding water for extraction. After inspection, the mass percentage of tea polyphenols, the signature component of the extract, is 4.1%. The extract is used as an active ingredient to prepare granules according to conventional techniques in the art.
Embodiment 3
[0023] The extract of Camellia japonica leaves is prepared by adding water to extract leaves of Camellia japonica, filtering the residue after adding water three times, combining the obtained filtrates, and drying under reduced pressure at a temperature of 80°C to obtain the extract. The process of adding water to extract plant leaves and filter residues is as follows: add 5 times the weight of water each time, heat to boiling, then stop fire, heat soak for 120 minutes, heat again to boil, then stop fire, and heat soak for 180 minutes. Plant leaves are dry leaves, which are soaked in water for 10 minutes before being heated to boiling when adding water to extract. After inspection, the mass percentage of tea polyphenols, the signature component of the extract, is 11.2%. Using the extract as an active ingredient, it is prepared into tablets according to conventional techniques in the art.
