Embodiment 1

[0026] 1) The sorted and cleaned medlars were sheared with a high-speed shearing machine at a speed of 10,000 rpm for 30 minutes, and extracted twice at 60° C. for 2 hours each time. Add 10 times purified water for the first extraction, and add 8 times purified water for the second extraction. After tubular centrifugation, concentrate with a membrane filtration device with a molecular weight of 3500Da to obtain a wolfberry extract and a spray-dried wolfberry glycopeptide extract. The obtained lycium barbarum glycopeptide is detected by the national standard detection method (sulfuric acid phenol method), and the content of the lycium barbarum polysaccharide is measured to be >50%.

[0027] 2) Use a high-speed shearing machine to shear the selected and cleaned black wolfberry at a speed of 10,000 rpm for 30 minutes, extract it twice at 60° C. for 2 hours each time, and add 5% Vc and 1% citric acid. Add 12 times 70% ethanol for the first extraction, and add 10 times 70% ethano...

Embodiment 2

[0030] 1) Take 20kg of the above-mentioned wolfberry extract, 4kg of black fruit wolfberry extract, 0.1kg of sorbitol, 3g of lutein, 5g of taurine, and 500g of xylo-oligosaccharide, and pass through a 80-mesh sieve.

[0031] 2) After the above-mentioned materials are homogenized, they are spray-dried, sterilized, and packaged to obtain a solid beverage of wolfberry extract.

[0032] The solid beverage that makes is carried out quality inspection, and result is as follows:

[0033] 1. Sensory indicators:

[0034] The obtained solid beverage has uniform color, mellow taste, unique fragrance of wolfberry, no agglomeration, and no moisture absorption.

[0035] 2. Physical and chemical indicators:

[0036] The net content of the obtained solid beverage is 5g / bag, and the content difference is less than 3%. According to the provisions of the Chinese Pharmacopoeia, the heavy metal content of the wolfberry extract solid beverage was measured, and the measurement results were lead <...

Embodiment 3

[0039]Mix 1200g wolfberry glycopeptide extract, 300g black fruit wolfberry extract, 0.53g lutein with 750g mannitol, 500g xylitol, 750g lactose, 8.5g citric acid, add povidone 2.5% and carboxymethyl The base cellulose calcium 3% was granulated, and vacuum-dried at 60° C. to obtain the first granule. The dry granules are sorted through a 12-mesh nylon sieve, and then the granules are fully mixed with 10.5g of magnesium stearate and 10.5g of talcum powder, and then passed through a 12-mesh nylon sieve. Chewable tablets are obtained after sterilizing and packaging.

[0040] The prepared chewable tablet is carried out quality inspection, and the results are as follows:

[0041] 1. Sensory indicators:

[0042] Table 1: Analysis results of sensory quality of chewable tablets

[0043]

[0044] 2. Physical and chemical indicators:

[0045] The average tablet weight of chewable tablets is 1g / tablet, and the difference in tablet weight is less than 3%. According to the provision...

Abstract

The invention aims to provide a composition with an effect of improving eyesight and a preparation thereof, and particularly provides a composition which takes black Chinese wolfberries and wolfberryfruits or extracts thereof as effective components and has the effect of improving eyesight. The composition provided by the invention combines the functions of relieving visual fatigue and achievingprevention and auxiliary treatment of eyesight problems such as failure of eyesight, nyctalopia, muscae volitantes, glaucoma and cataract caused by maculopathy, pigmented retinopathy and diabetic retinopathy, so that the eyesight can be improved to the maximum extent; and furthermore, from the traditional Chinese medicine theory, both the wolfberry fruits and the black Chinese wolfberries have theeffect of removing heat from the liver so as to improve eyesight.

Description

technical field [0001] The invention belongs to the technical field of extraction and application of active substances, and in particular relates to a composition with the effect of improving eyesight. Background technique [0002] Eyes are the windows of the soul, it brings people a bright world. With the continuous advancement of science and technology, the popularization of TV, computer and mobile phone has greatly increased the frequency of people using their eyes, so more and more eye health problems have begun to entangle in our lives.
