Embodiment 1

[0143] The production process of Pu'er tea extract:

[0144] The Pu'er tea leaves are boiled vigorously with water and extracted 3 times (1.5h, 1.5h, 1h; 10bv, 8bv, 8bv), the extract is filtered, and the filtrate is concentrated under reduced pressure (≤70℃) to tea (weight): concentrated liquid (volume) =1:2-1:3, the concentrate is centrifuged with a three-foot centrifuge, the three-foot centrifuge is centrifuged with a tube centrifuge, the centrifuge is concentrated under reduced pressure to a specific gravity of 1.1-1.25 (45-65°C), and the concentrated paste is spray dried Ready to get (or microwave drying and crushing to get).

[0145] Among them, tubular centrifugal conditions: centrifuge speed: 17000 rpm; spray drying conditions: inlet air temperature: 160°C, outlet air temperature: 85°C.

Embodiment 2

[0147] Step 1. Pu'er tea leaves were decocted and extracted 3 times, 0.5 hours each time, 6 times the volume of water; the extract was filtered, and the filtrate was concentrated under reduced pressure (≤70°C) to tea (weight): concentrated liquid (volume) = 1: 2,

[0148] Step 2. Centrifuge the concentrated liquid with a centrifuge, and concentrate the centrifugal liquid under reduced pressure to a specific gravity of 1.1 (45° C.). The concentrated paste can be obtained by spray drying (or microwave drying and crushing).

Embodiment 3

[0150] Step 1, decocting and extracting Pu'er tea leaves in water for 3 times, 2 hours each time, 12 times the volume of water; the extract is filtered, and the filtrate is concentrated under reduced pressure (≤70°C) to tea (weight): concentrated liquid (volume) = 1: 3.

[0151] Step 2: Centrifuge the concentrated liquid with a centrifuge, and concentrate the centrifugal liquid under reduced pressure to a specific gravity of 1.25 (65° C.), and the concentrated paste can be obtained by spray drying (or microwave drying and crushing).

Abstract

The invention relates to an application of a Pu'er tea extract in preparing hypotensive medicines or foodstuffs. The invention belongs to the fields of pharmacy and foodstuff. An extraction method provided by the invention comprises the two steps: step 1, Pu'er tea leaves are decocted by using water; an extraction liquid is filtered and condensed until a certain proportion is reached; and step 2, the concentrated solution is subjected to centrifugation, a centrifugate is concentrated and dried, such that the extract is obtained.

Description

Technical field [0001] The invention relates to an application of a Pu'er tea extract in the preparation of blood pressure lowering drugs or foods, and belongs to the field of pharmacy and health food. Background technique [0002] The origin of Pu'er tea is mainly in Simao area of ​​Yunnan and Xishuangbanna. With the promotion of large-leaf varieties, Sichuan, Guangdong, and Guangxi have also become provinces for Pu'er tea production. With the development of economy and the increasing awareness of people's health care, Pu'er tea has attracted the attention and attention of the whole society because of its mellow taste, its unique and excellent quality and its special health effects on the human body. The products are favored by consumers. . [0003] Pu'er tea is mild and durable in storage, suitable for cooking or brewing. There are many records about the efficacy of Pu'er tea in many historical records in ancient China: Zhao Xuemin’s "Supplements to Compendium of Materia Medic...
