Embodiment 1

[0034]Example 1 A preparation method of a medicinal and edible composition capable of resisting retinal blue light damage, comprising the following steps:

[0035] (1) Take 1 part of medlar, 2 parts of poria cocos, 3 parts of oyster, 2 parts of cassia seed, 1 part of chrysanthemum, and 1 part of dendrobium officinale, and mix them. Add water in an amount 8 times the weight of the medicinal material, reflux for extraction for 120 minutes, filter, and collect the filtrate and filter residue.

[0036] (2) Take the medicinal dregs in step (1), add water with a volume 10 times the weight of the medicinal material, extract under reflux for 120 minutes, filter, and collect the filtrate.

[0037] (3) Combine the filtrate obtained in step (1) and step (2), concentrate under reduced pressure to obtain extract, add 0.01 part of lutein and 0.01 part of taurine, and obtain the extract under low temperature and reduced pressure.

Embodiment 2

[0038] Example 2 A preparation method of a medicinal and edible composition capable of resisting retinal blue light damage, comprising the following steps:

[0039] (1) Take 2 parts of medlar, 2 parts of poria cocos, 2 parts of oyster, 3 parts of cassia seed, 2 parts of chrysanthemum, and 2 parts of Dendrobium officinale, and mix them. Add water in an amount 8 times the weight of the medicinal material, reflux for extraction for 120 minutes, filter, and collect the filtrate and filter residue.

[0040] (2) Take the medicinal dregs in step (1), add water with a volume 10 times the weight of the medicinal material, extract under reflux for 120 minutes, filter, and collect the filtrate.

[0041] (3) Combine the filtrate obtained in step (1) and step (2), concentrate under reduced pressure to obtain extract, add 0.08 part of lutein and 0.08 part of taurine, and obtain the extract under low temperature and reduced pressure.

Embodiment 3

[0042] Example 3 A preparation method of a medicinal and edible composition for resisting retinal blue light damage, comprising the following steps:

[0043] (1) 3 parts of medlar, 4 parts of Poria cocos, 6 parts of oyster, 4 parts of cassia seed, 3 parts of chrysanthemum, 3 parts of Dendrobium candidum, mixed. Add water in an amount 8 times the weight of the medicinal material, reflux for extraction for 120 minutes, filter, and collect the filtrate and filter residue.

[0044] (2) Take the medicinal dregs in step (1), add water with a volume 10 times the weight of the medicinal material, extract under reflux for 120 minutes, filter, and collect the filtrate.

[0045] (3) Combine the filtrate obtained in step (1) and step (2), concentrate under reduced pressure to obtain extract, add 0.05 part of lutein and 0.05 part of taurine, and obtain the extract under low temperature and reduced pressure.

Abstract

The invention discloses a medicine and food dual-purpose composition for resisting blue light damage to retina, and a preparation method and application of the composition. The composition is preparedfrom the following raw materials in parts by weight: 1-5 parts of Chinese wolfberry fruit, 2-6 parts of poria cocos, 4-8 parts of oyster, 2-6 parts of cassia seeds, 1-5 parts of chrysanthemum, 1-5 parts of dendrobium officinale, 0.01-0.1 part of lutein, and 0.01-0.1 part of taurine. The medicine and food dual-purpose composition provided by the present invention is capable of resisting blue lightdamage to the retina, has good safety, and can be used to prepare ordinary foods or healthcare products or medicines which resist asthenopia.

Description

technical field [0001] The invention relates to a medicinal and edible composition, in particular to a medicinal and edible composition capable of resisting blue light damage to the retina and its preparation method and application. Background technique [0002] In modern society, the impact of light pollution on human health has attracted more and more attention from the world. Light pollution is a new source of environmental pollution after waste gas, waste water, waste residue and noise pollution, mainly including white light pollution, artificial daytime pollution and colored light pollution. Among them, human beings have experienced a long evolution of more than 5,000 years, and gradually adapted to the "biological clock" formed by the sun and the 24-hour day and night alternation and seasonal changes caused by the sun. changes with the presence of light sources. Although the working hours can be extended, the unhealthy lighting environment and irregular work and rest...
