Product Informations

Mulberry leaf extract is the water or alcohol extract of dried leaves of mulberry plants. It contains flavonoids, alkaloids, polysaccharides and other active substances. It has pharmacological effects such as hypoglycemic, antibacterial, hypotensive and anti-inflammatory. Mulberry leaf extract is widely used in food, medicine, animal feed, beauty and so on.
1、 Main components
Mulberry leaf extract contains mulberry leaf flavonoids, mulberry leaf polyphenols, mulberry leaf polysaccharides, DNJ, GABA and other physiologically active substances.
2、 Function
1. Antihypertensive effect
The mulberry leaf extract was diluted and injected into the femoral vein of dogs after anesthesia, resulting in a temporary decrease in blood pressure, which did not affect breathing. Yunxiang glycoside in mulberry leaves also has the effect of reducing blood pressure.
2. Antispasmodic effect
Quercetin can reduce the tension of intestinal and bronchial smooth muscle. Rutin can reduce the gastric motor function of rats and relieve the spasm of small intestinal smooth muscle caused by barium chloride.
3. Anti aging effect
Mulberry leaf extract can improve the activity of free radical scavenging enzymes and reduce the brown matter in tissues to delay aging. The superoxide dismutase in its extract can catalyze the disproportionation of superoxide anion free radicals to produce molecular oxygen and hydrogen peroxide, and can remove free radicals in time, so as to protect the body from free radicals. It plays a very important role in human anti-aging.
4. Anti inflammatory effect
Rutin and quercetin have inhibitory effects on edema of feet and ankles caused by histamine, egg white, formaldehyde, 5-hydroxytryptamine and polyvinylpyrrolidone in rats, as well as edema of feet and ankles caused by hyaluronidase. Intravenous injection of rutin can inhibit the allergic inflammation of skin and joints and arthusphenomenon caused by horse serum in rabbits. Its effect may be caused by protecting the capillary wall, densifying capillaries and inhibiting exudation.
5. Antibacterial effect
In vitro experiment, the decoction of fresh mulberry leaves has strong inhibitory effect on Staphylococcus aureus, diphtheria bacilli, B hemolytic streptococcus, anthrax bacilli and so on. It also has a certain inhibitory effect on Escherichia coli, dysentery bacilli, Pseudomonas aeruginosa and typhoid bacilli. The high concentration Decoction of mulberry leaves (31mg / ml) had the effect of anti Leptospira in vitro. The volatile oil from mulberry leaves also has antibacterial and anti skin pathogenic fungi effects.
6. Hypoglycemic effect
Mulberry leaves reduced blood glucose and antidiabetic effects on experimental diabetic rats induced by alloxan, adrenalin, glucagon, and insulin resistance induced hyperglycemia in mice. Four. Peeling sterone in mulberry leaves also has hypoglycemic effect and can promote the conversion of glucose into glycogen. Some amino acids in mulberry leaves can stimulate the secretion of insulin, which can reduce the decomposition rate of insulin and reduce blood glucose as a regulatory factor for the secretion and release of insulin in the body.
3、 Application field
1. Medicinal development
Mulberry leaf extract has hypoglycemic, antitumor, antiviral, antibacterial and other pharmacological effects. Researchers have developed hypoglycemic drugs, antitumor drugs, antiviral drugs and antibacterial drugs.
2. Animal feed
Mulberry leaves and mulberry leaf powder, as livestock and poultry feed or additives, have good palatability and high nutritional value. Foreign countries have achieved good results in raising dairy cows, sheep, broilers, layers, rabbits and other animals with mulberry leaves.
3. Preservative
Mulberry leaf active ingredients, especially polyphenols, have strong inhibitory effect on the growth of most Gram-positive bacteria, Gram-negative bacteria and some yeasts, and have the characteristics of strong thermal stability, low inhibitory concentration and wide antibacterial pH range. Mulberry leaf active substances not only have no toxic and side effects, but also have health care functions. Therefore, they can be used as natural preservatives for high-grade food.
4. Beauty cosmetics
The active components of mulberry leaves have the effects of anti-oxidation, anti-aging, bacteriostasis and moisturizing. Japan, South Korea and the United States vigorously study the active components of mulberry leaves, especially DNJ, optimize the purification process of mulberry leaf DNJ, prepare high-purity DNJ and use it in the production of beauty cosmetics.
