1. Hypoglycemic effect: Buckwheat bioflavonoids can promote the recovery of islet β cells, reduce blood sugar and serum cholesterol, improve glucose tolerance, and resist the hypoglycemic effect of epinephrine. At the same time, it can also inhibit aldose reductase, so it can treat diabetes and its complications.
2. Hypolipidemic effect: Quercetin, which is rich in bioflavonoids from tartary buckwheat, can reduce triglyceride, total cholesterol and atherosclerosis index.
Second, the impact on the cardiovascular system.
Effect of 1. on myocardium: It can be used to treat arrhythmia, angina pectoris and myocardial infarction.
2. Effect on blood vessels: Rutin, a bioflavonoid rich in tartary buckwheat, can dilate blood vessels, while quercetin and morin can improve the contraction and relaxation function of vascular smooth muscle.
Third, antibacterial and antiviral effects.
According to research, quercetin, morin and camphor rich in tartary buckwheat have antibacterial and antiviral effects. The clinical application of the flavone has peculiar effects of removing putrefaction, promoting granulation, diminishing inflammation and relieving pain for ulcers caused by various reasons.
Fourth, the antioxidant effect.
3-OH, 5-OH, 4- groups and 2,3- position double bonds play a leading role in inhibiting the automatic oxidation of oils and fats. The ability of inhibiting oil oxidation quercetin > morin > rutin.
Five, cancer prevention, anti-cancer effect
Flavonoids such as quercetin, a bioflavonoid rich in tartary buckwheat, have achieved anti-cancer effects mainly through three ways, namely, anti-free radical effect, direct inhibition of cancer cell growth and anti-carcinogenic factors. Pentagonal flavonoids contained in biological flavonoids of tartary buckwheat are the first choice for anti-cancer, anti-cancer and cancer treatment.
Six, scavenging free radicals
Free radicals are the evil sources leading to cancer, aging and cardiovascular and cerebrovascular degenerative diseases. Because tartary buckwheat flavonoids are easy to oxidize and have scavenging ability. They have five hydroxyl groups, which can be used as hydrogen donors to reduce free radicals, thus achieving the purpose of eliminating free radicals and preventing aging, cancer and cardiovascular and cerebrovascular diseases.
Seven, the influence on bone tissue
Buckwheat bioflavonoids can be used to treat bone diseases and osteoporosis, and its mechanism lies in the following aspects: firstly, it can not only inhibit the increase of collagen synthesis of prostaglandin E2(PGE2), but also inhibit the decrease of collagen synthesis of PGE2, that is, it can inhibit {BH }- proline from entering digestible collagen and non-collagen protein, which mainly acts on non-collagen synthesis at low concentration of PGE2, and mainly acts on collagen synthesis at high concentration of PGE2.
Therefore, it can be used to treat bone diseases; Secondly, it can improve the sensitivity of thyroid gland to estrogen, strengthen the secretion of calcitonin by thyroid C cells, and finally inhibit bone absorption to treat osteoporosis; Third, it can inhibit the decrease of bone mineral density and bone calcium content caused by dietary calcium deficiency and vitamin D.
Eight, the impact on the immune system
Buckwheat bioflavonoids can obviously and effectively increase the nonspecific immune function and humoral immune function of the body.
Nine, the role of protecting the liver
Buckwheat bioflavonoids have a certain effect on acute and chronic hepatitis, liver cirrhosis, fatty liver and toxic liver injury caused by galactosamine and carbon tetrachloride.
The results showed that tartary buckwheat flavonoids had obvious inhibitory effect on the increase of malondialdehyde (MDA) induced by carbon tetrachloride in liver. It can reduce the activity of soluble enzymes such as transaminase in liver cells increased by cell leakage; The liver-protecting mechanism of tartary buckwheat bioflavonoids ultimately lies in its antioxidant and anti-free radical effects.
Anti-ultraviolet function
Flavonoids such as quercetin, a bioflavonoid rich in tartary buckwheat, are a sunscreen and have the function of absorbing ultraviolet rays. It can protect bioactive substances such as ascorbic acid from oxidation and keep its activity. It is an excellent antioxidant, and its chelation and gene expression can obviously reduce the oxidative denaturation of fat. Flavonoids, in particular, have significant health care effects on skin, youth and blood vessels, as well as anti-inflammatory effects, so some people call them "skin nutrients".
People also prepared tartary buckwheat protein complex (TBPC) from tartary buckwheat, and studied its nutritional components and anti-aging effects. The results showed that the content of protein in tartary buckwheat complex protein was 63.4, fat 12.7, carbohydrate 10.2, ash 3.5, crude fiber 0.4 and water 9.8. At the same time, it also contains a variety of amino acids, and its essential amino acids and non-essential amino acids account for about 45.8% of all amino acids, and contain certain fatty acids and trace elements.
