Embodiment 1

[0087] Embodiment 1 water extraction method prepares the traditional Chinese medicine composition for alleviating asthenopia

[0088]Method 1: Weigh 20 kg of cassia seed, 20 kg of sealwort, 20 kg of Polygonatum odoratum, 20 kg of chrysanthemum, 20 kg of orange peel and 20 kg of mulberry leaf, extract with water as solvent, soak in 0.60 tons of water for 20 minutes, heat and extract 3 times (extract 2.5h for the first time, extract 1h for the second time, extract 30min for the third time, and the extraction time of each time starts to calculate after boiling), combine the extracts, and concentrate the extracts obtained until the volume of the extracts is the 3 times the weight of the raw material to obtain a preliminary concentrated extract; further dry to a relative density of 1.0g / cm 3 of extracts.

[0089] Grind the extract obtained above into powder, weigh 1 kg of wolfberry, 1 kg of black wolfberry, and 1 kg of Chinese yam and grind into powder, and finally add 0.5 kg of e...

Embodiment 2

[0094] Embodiment 2 alcohol extraction method prepares the Chinese medicine composition for alleviating asthenopia

[0095] Method 1: Weigh 20 kg of cassia seed, 20 kg of sealwort, 20 kg of Polygonatum odoratum, 20 kg of chrysanthemum, 20 kg of orange peel and 20 kg of mulberry leaf, extract with 65% ethanol as solvent, soak 0.60 tons of 65% ethanol for 20 minutes, Heated and extracted 3 times, the first extraction was 2.5 hours, the second extraction was 1 hour, and the third extraction was 30 minutes. The extraction time of each time was calculated after boiling (the extraction time of each reflux was calculated after boiling), and the extraction liquid Merge, let stand for 24 hours, filter to take the supernatant, concentrate the supernatant to 3 times of the original medicinal material, and obtain a preliminary concentrated extract; further dry to a relative density of 1.0g / cm 3 of extracts.

Abstract

The invention provides preparation methods and application of a traditional Chinese medicine composition capable of alleviating asthenopia. The invention provides 6 preparation methods: (1) a water extraction method; (2) an alcohol extraction method; (3) a water-extraction and alcohol-precipitation method; (4) a method combining water extraction with macroporous resin purification; and (5) a method combining alcohol extraction with macroporous resin purification. According to the preparation methods disclosed by the invention, technology optimization of an extract is performed on a formula, various preparations of traditional Chinese medicines (or health-care foods or common foods) are prepared, and main components of activity parts are delimited. An extract oral preparation is provided, prepared products are detected, clear and definite active substance bases (consisting of a plurality of effective components having a certain proportion) of the extract are reflected, and the content is high.

Description

technical field [0001] The invention relates to a preparation method and application of a traditional Chinese medicine composition for alleviating visual fatigue, belonging to the technical field of traditional Chinese medicine.
