Problems solved by technology

The traditional decoction pieces of Centella asiatica are made by removing impurities, washing, cutting into sections, and drying the medicinal herbs of Centella asiatica. It is bulky and fluffy, making it difficult to store and pack
The Chinese invention patent with the application number 01100033.3 discloses a kind of nano Chinese medicine decoction piece and its preparation method, which is to crush the traditional Chinese medicine into an ultrafine powder below 500 nanometers. The preparation cost of this ultrafine powder is too high because the plant The cell wall is quite different from the structure of traditional Chinese medicine decoction pieces, so it does not have the equivalence with traditional Chinese medicine decoction pieces in terms of efficacy

Embodiment 1

[0034] The traditional decoction pieces of Centella asiatica are crushed, sieved, and the unsifted parts are repeatedly crushed until all of them pass through a 100-mesh sieve. Pre-treatment of the powder: heat the powder in an oven at 60°C for 4 hours to fully inactivate the enzyme. Process: The pre-treated powder and water are mixed at a ratio of 1: 1.4 to obtain soft materials, granulated (screen aperture 1.0mm), and the wet particles are shot in a centrifugal ball blasting machine (speed 600rpm, time 30min ), the prepared wet shot blasting is placed in a blast drying oven and dried at a temperature of ≤80°C. Take it out and let it cool down to room temperature, sieve it, and take 10-24 mesh shot balls to obtain liquid decoction pieces (shot balls) of Centella asiatica.

Embodiment 2

[0036] The traditional decoction pieces of Centella asiatica are crushed, sieved, and the unsifted parts are repeatedly crushed until all of them pass through a 95-mesh sieve. Pre-treatment of medicinal powder: high-temperature treatment in an oven at 55°C for 4 hours to fully inactivate the enzyme. Process: The pre-treated powder and water are mixed in a ratio of 1:4 to obtain soft materials, granulated (screen aperture 1.0mm), and the wet granules are shot in a centrifugal ball blasting machine (rotating speed 600rpm, time 30min ), the prepared wet shot was placed in a blast drying oven, and dried at a temperature of 80°C. Take it out and let it cool down to room temperature, sieve it, and take 10-24 mesh shot balls to obtain liquid decoction pieces (shot balls) of Centella asiatica.

Embodiment 3

[0038] The traditional decoction pieces of Centella asiatica were crushed, sieved, and the unsifted parts were repeatedly crushed until all passed through a 105-mesh sieve. Pre-treatment of medicinal powder: high-temperature treatment in an oven at 65°C for 5 hours to fully inactivate the enzyme. Process: The pre-treated powder and water are mixed at a ratio of 1: 1.3 to obtain soft materials, granulated (screen aperture 1.0mm), and the wet particles are shot in a centrifugal ball blasting machine (speed 600rpm, time 35min ), the prepared wet shot blasting is placed in a blast drying oven, and dried at a temperature of about 70°C. Take it out and let it cool down to room temperature, sieve it, and take 10-24 mesh shot balls to obtain liquid decoction pieces (shot balls) of Centella asiatica.

Abstract

The invention discloses centella asiatica (L.) Urban fluid decoction pieces and a preparation method thereof. The decoction pieces are suitable for standardized production and mechanized packaging, and have high decocting rate and less effective component loss. The invention aims to make standardized production and mechanized packaging easier under the premise of maintaining original medicine components, reaches stable and reliable quality and automatic packaging of Chinese herbal pieces, and meets the industrialization requirement of Chinese herbal pieces. The centella asiatica (L.) Urban fluid decoction pieces are prepared by the following method: a. medicinal material crushing: crushing traditional centella asiatica (L.) Urban decoction pieces or finished and selected centella asiatica (L.) Urban, conducting sieving through a sieve of 95-105 meshes, thus obtaining medicinal powder; b. enzyme killing of the medicinal powder: subjecting the medicinal powder to enzyme killing in a baking oven at a temperature of 55-105DEG C for more than 4h; c. blast shot preparation: mixing the treated medicinal powder with a proper amount of water so as to obtain a soft material, carrying out granulation, putting wet particles in a shot blasting machine for shot blasting, and drying the obtained wet blast shots at a temperature lower than or equal to 80DEG C, taking the blast shots out and placing them under room temperature, performing sieving, and taking blast shots of 10-24 meshes, thus obtaining the centella asiatica (L.) Urban fluid decoction pieces.

Description

technical field [0001] The invention relates to a decoction piece of a traditional Chinese medicine, in particular to a fluid decoction piece of Centella asiatica, belonging to the technical field of traditional Chinese medicine. Background technique [0002] Chinese herbal decoction pieces are Chinese medicinal materials that have been processed according to the theory of traditional Chinese medicine and the processing methods of traditional Chinese medicine, and can be directly used in Chinese medicine clinics. The decoction pieces of traditional Chinese medicine include slices of traditional Chinese medicine processed by the place of origin (including slices, blocks, and petals), the decoction pieces of original medicinal materials, and the pieces of decoction pieces that have been cut (based on processing in the place of origin) and roasted. Centella asiatica is the dry or rooted whole grass of Centella asiatica (L.) Urban, Umbelliferae Umbelliferae. Harvest in summer a...
