preparation example Construction

[0045] The present application also provides a preparation method of the aforementioned composition having the function of alleviating visual fatigue, comprising the following steps:

[0046] (a) extracting blueberries to obtain blueberry paste;

[0047] (b) Put 500-1000 parts of medlar into water and decoct to obtain a density of 1.30-1.36g / cm 3 the first concentrate;

[0048](c) mixing the first concentrate with 640-800 parts of blueberry cream, 1-1.8 parts of nicotinamide, and 1-1.8 parts of lutein to obtain a composition capable of alleviating visual fatigue.

[0049] Extracting the blueberry paste in step (a) can be prepared by the aforementioned method, which will not be repeated here. In one implementation of step (b), 500 to 1000 parts of Lycium barbarum can be put into water and decocted at least once, wherein the mass ratio of Lycium barbarum to water is 1:6 to 10, and each decoction time is 1 ~2 hours. Here, the decocting step may only be decocted once, or may b...

Embodiment 1

[0056] Take 700g of medlar, add 6 times the amount of medicinal materials to decoct once for 1 hour each time, filter, combine the filtrate, concentrate the filtrate under reduced pressure to a relative density of 1.30-1.36 (measured at 60°C), and set aside. Take 640g of blueberry paste and mix it with the above concentrate, add 1.0g of nicotinamide and 1.0g of lutein, and mix to obtain composition paste 1.

Embodiment 2

[0058] Take 700g of medlar, add 8 times the amount of medicinal materials to decoct once for 1 hour each time, filter, combine the filtrate, concentrate the filtrate under reduced pressure to a relative density of 1.30-1.36 (measured at 60°C), and set aside. Take 640g of blueberry paste and mix it with the above concentrate, add 1.0g of nicotinamide and 1.0g of lutein, and mix to obtain composition paste 2.

Abstract

The embodiment of the invention discloses a composition with the function of relieving visual fatigue. The composition is composed of, by weight, 10,000-20,000 parts of blueberries, 500-1,000 parts ofChinese wolfberry fruits, 1-1.8 parts of nicotinamide and 1-1.8 parts of xanthophyll. The composition can be used for preparing health-care foods or medicine for relieving visual fatigue, under the synergistic effect of the blueberries, the Chinese wolfberry fruits, nicotinamide and xanthophyll, the SOD and GSH-Px activity of retina cells can be effectively improved, the content of total proteinsof the retina cells can be effectively increased, the MDA content is remarkably decreased, the completeness of all layers of cells of the retina can be further protected, damaged cells are improved,the thickness of the outer nuclear layer of the retina is increased, and therefore a good effect of relieving visual fatigue is realized. In addition, the composition is free of toxic and side effectsand high in safety.

Description

technical field [0001] The invention relates to the field of compositions for relieving visual fatigue, in particular to a composition capable of relieving visual fatigue. In addition, the present invention also relates to the preparation method of the composition and its application in health food or medicine. Background technique [0002] Asthenopia is a common ophthalmic disease. The disease generally does not exist independently, but is a fatigue syndrome caused by various factors. It usually manifests as eye pain, soreness, foreign body sensation, blurred vision, and dry eyes. Wait. The causes of visual fatigue are complex, and the common triggers mainly include diseases of the eye itself, such as myopia, keratitis, macular degeneration, etc. In addition, environmental factors are also the main factors causing visual fatigue, such as: strong light or ultraviolet rays irradiating the eyes, radiation from long-term use of electronic products, etc., all of which will gen...
