Embodiment 1

[0094] The preparation of embodiment 1 Pu'er tea extract

[0095] Wherein each component accounts for the percentage by weight of extract gross weight:

[0096] Tea polyphenols: 55.85%

[0097] Tea polysaccharide: 14.87%

[0098] Caffeine: 7.81%

[0099] Theabrownin: 23.11%

[0100] Take Pu-erh tea, pour into groups for countercurrent circulation extraction, each group consists of 3 cans; each can is boiled and decocted for 4 extractions, each time adding 6 times of water, and each extraction time is 1h; the first extraction of each can enters the liquid storage tank , the subsequent extraction solution of each tank is used as the extraction solvent of the next tank in turn; the tank that completes the extraction is added with new raw materials and enters the cycle to start a new extraction. Tea leaves (weight): concentrated solution (volume) = 1:4, the concentrated solution was left to stand at 5°C for 12 hours, the supernatant was filtered with a filter element (precisio...

Embodiment 2

[0101] The preparation of embodiment 2 Pu'er tea extract

[0102] Take Pu’er tea, pour into groups for countercurrent circulation extraction, each group consists of 3 cans; each can is boiled and decocted for extraction 4 times, each time adding 8 times of water, and each extraction time is 1h; the first extraction of each can enters the liquid storage tank , the subsequent extraction solution of each tank is used as the extraction solvent of the next tank in turn; the tank that completes the extraction is added with new raw materials and enters the cycle to start a new extraction. Tea leaves (weight): concentrated solution (volume) = 1:3, the concentrated solution was left to stand at 5°C for 12 hours, the supernatant was filtered with a filter element (precision 5 microns), and the filtrate was concentrated under reduced pressure at 60°C at a temperature of ≤70°C The measured specific gravity is 1.13, and the concentrated paste is microwave-dried. Detect by following method...

Embodiment 3

[0145] Embodiment 3, the preparation of Pu'er tea extract

[0146] Take Pu-erh tea, pour into groups for countercurrent circulation extraction, each group is composed of 5 cans; each can is boiled and decocted for 8 extractions, each time adding 3 times of water, and each extraction time is 1.5h; the first extraction of each can enters the storage solution The subsequent extraction solution of each tank is used as the extraction solvent of the next tank in turn; the tank that completes the extraction is added with new raw materials and enters the cycle to start a new extraction. The extract is filtered at 300 mesh, and the filtrate is concentrated under reduced pressure at a temperature of ≤70°C To tea leaves (weight): concentrated solution (volume) = 1: 5, the concentrated solution was allowed to stand at 5°C for 12 hours, the supernatant was filtered with a filter element (precision 5 microns), and at a temperature of ≤70°C, the filtrate was concentrated under reduced pressur...

Abstract

The invention relates to an extractive of the traditional Chinese medicine and preparation thereof, in particular to the extractive of Pu'er tea and the preparation method thereof; wherein the preparation method comprises the technical means such as countercurrent extraction in pot groups, concentration, filtration and the like.

Description

technical field [0001] The invention relates to a traditional Chinese medicine extract and its preparation, in particular to an extract of Pu'er tea and its preparation. Background technique [0002] Pu'er tea is a famous local tea unique to Yunnan. There are two series of large-leaf sun-dried green tea from Yunnan and its reprocessing: raw Pu-erh tea that is directly processed into finished products, and cooked Pu-pu tea that is processed after artificial accelerated fermentation. There are two types of pressed tea; after the finished product, the natural aging process continues, and it has the unique quality of getting better with age. Pu-erh tea is made from the fresh leaves of the fine variety Yunnan big-leaf species, also known as Pu-erh loose tea. Its shape is thick and fat, and its color is black or brownish red, commonly known as pig liver color. The taste is mellow and sweet, with a unique aged fragrance, and has the reputation of "beauty tea". [0003] Pu-erh t...
