source plant | blueberry, also known as bilberry, belongs to the genus Vaccinium of duchenaceae, perennial deciduous or evergreen shrub, flowers are white or pink, the blueberry fruit is dark blue, the peel is covered with a layer of white fruit powder, is one of the few blue food. Blueberries are rich in a variety of antioxidants, with antioxidant, cancer prevention, relieve asthenopia, improve immunity and other health effects. Blueberry, as a superior health food, is included in the third generation fruit after apple and citrus, one of the five health foods for human beings. [Distribution and cultivation] Blueberry native to North America, including blue fruit blueberry in the scope of the largest area of cultivation, commonly known as blueberries. The cultivation history of blueberry is relatively short, and the research on domestication was first started in the United States (1908). The introduction and domestication of blueberry in China have been carried out since the Eighties of the 20th century. About more than 130 species of blueberry, distributed in the northern hemisphere from the Arctic to tropical alpine regions. There are about 20 species in China, which are widely distributed in the northeast and southwest mountainous areas. Blueberries can be divided into cultivated and wild species. The most commonly cultivated species in North America is the northern high plexus blueberry. Chile is the second largest exporting country of blueberries in the world, after the United States. [Chemical composition] Blueberry is rich in protein, fat, minerals, vitamins and other nutrients and anthocyanins, flavonoids, polyphenols and other large amounts of bioactive substances, both can be processed into nutrient-rich blueberry food, but also has the health effect, is a collection of nutrition and health care in one of the berries. There are many kinds and high contents of flavonoids in blueberry, mainly including anthocyanidins, flavanols, proanthocyanidins and quercetin, which are the main active ingredients of this genus. Among them, the study of anthocyanidins is the earliest. There are about 30 kinds of anthocyanins, of which 15 are common. There are five kinds of glycosidic pigments: anthocyanins (also known as anthocyanidins, anthocyanidin), delphindin (also known as delphindin), Mallow pigment (also known as dimethylol, malvidin), paeoniflorin (peonidin), Petunia aglycone (also known as 3-methoxycycline, petunidin). There are three types of sugars: glucose, galactose, and arabinose. These five ligands and three glycosyl groups are composed of monosaccharides to triglycosides, which are the most important anthocyanins. [Functional Indications] softening capillaries, eliminate eye fatigue, improve vision; Delay brain nerve aging; Enhance heart function; Anti-cancer; Have therapeutic effect on capillary immune disease caused by diabetes. The important role of anthocyanin pigment in blueberry leaves is to promote the re-synthesis of rhodopsin, thereby enhancing human vision. In modern society, the widespread popularity of television, cars and calculators, the increase in work stress and life stress, eye fatigue and associated eye diseases are increasing, according to the recommendations of American nutritionists, daily use of blueberry leaf extract 3 capsules, can achieve the purpose of eye health. Anthocyanins are a natural anti-aging nutritional supplement that has been shown to be the most effective antioxidant found today. The antioxidant properties of anthocyanins are 50 times higher than that of vitamin E and two hundred times higher than that of vitamin C. Its biological effectiveness on the human body is one hundred percent, 20 minutes after taking can be detected in the blood, help prevent a variety of diseases related to free radicals, including cancer, cardiovascular and cerebrovascular diseases, arteriosclerosis, aging, diabetes. Figure 1 shows blueberries. |
efficacy and function | 1. Antioxidant effect: Blueberry anthocyanin is a natural water-soluble free radical scavenger, its oxidation resistance is 20 times of VC, 50 times of VE. Blueberry anthocyanins have the ability of anti-lipid peroxidation, reducing ability and scavenging superoxide anion free radicals and hydroxyl radicals. Blueberry pomace flavonoids had strong antioxidant capacity, especially after purification, the antioxidant capacity of flavonoids was enhanced. The DPPH scavenging ability of total phenols from blueberry pomace was 26.7mgVc/g fresh weight. The scavenging ability of oxygen free radicals was 24.8mg VC/g fresh weight. Blueberry polysaccharide has strong scavenging ability on oxygen free radicals and DPPH. 2, antibacterial, anti-inflammatory and analgesic effects: blueberry extract can inhibit the growth of harmful bacteria, promote the proliferation of beneficial bacteria. Studies have shown that blueberry extract has inhibitory effect on Escherichia coli, Staphylococcus aureus and Vibrio parahaemolyticus, and adding appropriate concentration of blueberry extract to fermented milk can promote the growth of beneficial Lactobacillus acidophilus in vitro. Wang Jing and other studies have confirmed that blueberry anthocyanin can improve the pain threshold of mice, inhibit ear swelling, has obvious analgesic and anti-inflammatory effects. 3, protect vision: to prevent blindness, glaucoma, cataract, retinal hemorrhage, improve myopia, macular degeneration, diabetic retinopathy, retinitis pigmentosa and night blindness. The retina is located in a hyperoxic environment and is vulnerable to oxidative damage by long-term visible light irradiation. Blueberry contains a variety of bioactive ingredients, has the effect of protecting eyesight. Studies by Meng Xianjun and others show that blueberry anthocyanins can make the retinal structure of rats with light damage clear, and the cells are arranged in order; Effectively prevent the thickness of the outer nuclear layer of the retina and reduce the total protein content of the retina; the activity of SOD and GSH-Px in retinal cells was significantly increased, and the content of MDA was decreased. Blueberry anthocyanins have obvious protective effect on retinal damage in rats. 4. Inhibition of swelling and limping: The anticancer effect of blueberry anthocyanins has been confirmed in a variety of cell culture systems. Jin Junhua studied the inhibitory effect of blueberry extract on the proliferation of human colon cancer cell line HCT116 in vitro. The results showed that blueberry extract could induce the increase of apoptosis key protein Caspase-3 in HCT116 tumor cells and significantly inhibit the expression of NF-kB protein, HCT116 tumor cells are induced to apoptosis and inhibit their growth and proliferation in vitro. 5, cerebrovascular: strengthen cerebrovascular disease, prevention of cerebrovascular disease, strengthen myocardial blood vessels, strong coronary artery, strengthen renal blood vessels, prevention of glomerular capillary rupture and hematuria, urethritis and cystitis. Strengthen venous blood vessels, prevention of varicose veins, prevention and treatment of ulcers. Prevent arteriosclerosis; Prevent the formation of thrombus. 6, capillary: increase the flexibility of the capillaries, can be pure to promote vascular expansion and scalability, to prevent vascular rupture. Bilberry can strengthen the capillaries in the eyes, of course, can also strengthen the capillaries in other organs and tissues of the body, to prevent the vascular lesions of various organs. In addition, blueberry extract has the effects of preventing cardiovascular diseases, inhibiting obesity, improving diabetes and preventing osteoporosis. |
