Technical Field

The invention relates to the field of medicinal materials, in particular to a black wolfberry lutein chewable tablet for protecting eyesight and a preparation method thereof.

Background

Eye fatigue becomes a common disease of contemporary people, and dry eyes, sour eyes, swollen eyes, blurred vision and even visual deterioration caused by the eye fatigue directly influence the work and life of people. The eyestrain is mainly caused by that people watch the screens of computers, televisions and mobile phones for a long time, the number of blinking is reduced, tear secretion is correspondingly reduced, and rays and radiation harm are caused. Young people in the multi-screen age are often in a tension state of over-fatigue of eyes, and unclear vision, myopia, dryness and swelling become common phenomena and are important manifestations of eye sub-health. The development of a product with the effects of protecting eyesight and providing eye nutrition has very important practical significance, and can help a user to enhance eye nutrition, protect eyesight and relieve eye fatigue.

The Chinese invention patent publication No. CN107519338A, entitled "a Chinese medicinal composition for protecting eyesight by external use", specifically discloses that the Chinese medicinal composition comprises the following raw material medicaments: the external application of the externally applied medicine on the periphery of eye sockets is matched with a physical therapy instrument, and the clinically detected medicine has obvious curative effects on visual fatigue symptoms such as visual disturbance, eye drowsiness, photophobia, ache, lacrimation, foreign body sensation, dry eye, eye spasm and the like.

The traditional Chinese medicine composition is prepared from a plurality of raw materials, mainly aiming at external stimulation, and is complex to prepare and produce, and the obtained traditional Chinese medicine composition has a single function, only has a simple external stimulation effect applied to eyes to relieve symptoms, and cannot provide nutrition for the eyes from the mechanism; the effects of protecting eyesight, providing eye nutrition and relieving eye fatigue can not be achieved by oral administration and mechanically regulating and controlling various active ingredients; the raw materials and mechanisms adopted by external application and oral administration are completely different. The invention takes orally, leads active substances to participate in the physiological metabolism of eye cells, and achieves the effects of protecting vision, relieving asthenopia, preventing ultraviolet rays from damaging eyes, preventing macular degeneration of the retina of the eyes, promoting the proliferation of erythrocyte, resisting oxidation, clearing liver and improving vision, improving immunity and the like.

Disclosure of Invention

The invention utilizes the lutein as the main component of the macula lutea in eyes, can prevent the aging of the macula lutea, has the filtering function on ultraviolet rays, and can prevent and treat the damage of the ultraviolet rays to the eyes and the vision.

The cassia seed is a traditional Chinese medicine food material, and contains active ingredients such as chrysophanol, emodin, cassia tora essence, aurantio-obtusin and vitamin A according to the record of a Chinese medicine dictionary. The cassia seed recorded in Chinese pharmacopoeia has the efficacies of clearing liver and improving vision, red eyes and unsmooth eyes and poor vision.

Kudzu vine root is a core medicinal material for improving eyesight and protecting liver, contains active ingredients such as puerarin, puerarin xyloside, soybean flavone, beta-sitosterol, arachidic acid and the like, and the modern research shows that kudzu vine root flavonoid substances can increase the supply of blood to oxygen and relieve vision and physical fatigue.

The extract of lycium ruthenicum and mulberry contains anthocyanin as main component, which has the functions of resisting oxidation and scavenging free radicals, because the anthocyanin belongs to flavone substances. The main physiological activity of the flavone substance is to remove free radicals or oxidation resistance, and simultaneously, the flavone substance has the functions of protecting capillaries, increasing the regeneration of visible red blood cells and protecting eyes and eyesight. Research shows that anthocyanin is found by people at present, and the most effective antioxidant is also a stronger free radical scavenger, so that the anthocyanin has great benefits on relieving fatigue and resisting aging; meanwhile, the anthocyanin is not only a nutrient enhancer in food, but also a natural additive of food, and has irreplaceable effect as a preservative of food.

The cowberry fruit is rich in anthocyanin, and has effects of protecting capillary vessel, increasing regeneration of erythrocyte, and protecting eye and vision.

Xanthophyll, the main component of macula lutea in eyes, can prevent the aging of macula lutea, has filtering effect on ultraviolet, and can prevent and treat the damage of ultraviolet to eyes and eyesight.

Vitamin C is structurally similar to glucose, and is a polyhydroxy compound in which two adjacent enol-type hydroxyl groups at the 2 nd and 3 rd positions in the molecule are easily dissociated to release H +, and thus has an acid property, which is also called ascorbic acid. Vitamin C is necessary for antibody and collagen formation, tissue repair (including certain oxidation-reduction effects), metabolism of phenylalanine, tyrosine and folic acid, utilization of iron and carbohydrate, synthesis of fat and protein, maintenance of immune function, hydroxylation of 5-hydroxytryptamine, blood vessel integrity maintenance, non-heme iron absorption promotion and the like, and simultaneously the vitamin C also has the effects of oxidation resistance, free radical resistance and tyrosinase inhibition, so that the effects of resisting aging and nourishing optic nerve cells are achieved.

Vitamin A has multiple physiological functions of promoting growth and reproduction, maintaining normal secretion of bones, epithelial tissues, eyesight and mucous epithelium, and the like, and has a protective effect on optic nerves.

Beta-carotene is an antioxidant. After the beta-carotene enters the body, 50% of the beta-carotene is changed into vitamin A under the action of enzyme in the liver and small intestine mucosa, has the functions of tonifying liver and improving eyesight, and can be used for treating nyctalopia; benefiting diaphragm and widening intestine. The beta-carotene can be converted into vitamin A after entering human body, and the conversion has adjustability.

The invention has the beneficial effects that:

the cassia seed is a traditional Chinese medicine food material, and contains active ingredients such as chrysophanol, emodin, cassia tora essence, aurantio-obtusin and vitamin A according to the record of a Chinese medicine dictionary. Has the effects of clearing liver and improving vision, and relieving pain and darkness; the xanthophyll is the main component of macula lutea in eyes, and can prevent aging of macula lutea, filter ultraviolet, and prevent and treat ultraviolet injury to eyes and eyesight. Radix Puerariae and flos Chrysanthemi are combined for clearing liver-fire, improving eyesight, relieving asthenopia and reducing blood lipid. The black wolfberry, the mulberry and the cowberry fruit contain rich anthocyanin, protect capillary vessels, increase the regeneration of visual red cells, effectively protect eyes and eyesight and prevent and treat the damage of ultraviolet rays to the eyes. The lycium barbarum polysaccharide has stronger biological activity, is easy to absorb and utilize, and has better effects of reducing high blood pressure, high blood sugar, high blood lipid, high blood pressure, high blood sugar, high blood fat, high blood. The vitamin A can effectively improve the generation of the rhodopsin in the eyes and reduce the dryness degree of the eyes and the night blindness phenomenon. The raw materials for preparing the medicine composition for protecting eyesight and relieving asthenopia are fewer, the synthesis process is simple, the production cost is reduced, besides the simple function of relieving asthenopia, the medicine composition also has various medicinal effects of relieving spasm, resisting inflammation, reducing blood pressure, preventing cardiovascular and cerebrovascular diseases and the like, and the medicine functions are enriched.
