What is Betulin?
Betulin is also known as betulin and betulin. It is soluble in ethanol, ether, chloroform and benzene, and slightly soluble in organic solvents such as cold water and petroleum ether. It is a natural compound extracted from birch trees, specifically from the bark of birch trees. Birch trees like sunlight and have strong vitality. After the destruction of forest fires, the first to grow are often birch trees, and then large birch forests will be formed. Birch trees are widely distributed. The main distribution areas in China are Lesser Khingan Mountains, Greater Khingan Mountains, Changbai Mountains, and high mountains in North China. Birch trees are known as "living fossils among woody plants" and are one of the most vigorous and restorative tree species. Betulin is a large natural penetration enhancer. A concentration of 0.4% betulin promotes the percutaneous penetration of active substances by 34%. This compound is not only found in the bark of birch trees, but can also be found in other plants, such as the bark of the Asteraceae plant Cloudwood and the Betulaceae plant Birch. The discovery and application of betulin demonstrates the rich and diverse chemical substances in nature and provides a potential source of raw materials for medicine, cosmetics and other fields.
What Are The Functions Of Betulin?
Betulin has a wide range of biological activities. After verification by a variety of animal models and cell models, it is known that betulin has functional characteristics such as expectorant and cough relieving, melanin inhibition, blood lipid reduction, liver protection, anti-inflammatory, and improvement of Alzheimer's disease (AD).
- Inhibition of melanin formation
Btulin can be used as a natural, safe and side-effect-free Chinese medicine phytoestrogen. It inhibits A375 cell melanin synthesis through the p38-MAPK signaling pathway, reduces excessive skin pigmentation, improves the effect of chloasma on the patient's appearance, and is not affected by side effects.
- Blood lipid reduction
Btulin has a good pharmacological effect in anti-hyperlipidemia and can simultaneously reduce blood cholesterol and triglycerides. In addition, it can also inhibit the function of cholesterol regulatory element binding protein (SREBP), thereby affecting cholesterol metabolism, significantly reducing blood triglyceride, fatty acid and cholesterol levels, improving hyperlipidemia and insulin resistance in obese patients, and has a significant therapeutic effect on type 2 diabetes.
- Hepatoprotective effect
Buttiol has a certain therapeutic effect on rats with alcoholic fatty liver disease, can significantly improve the fatty degeneration and necrosis of liver tissue caused by alcohol, inhibit the damage of liver tissue to alcohol-induced lipid peroxidation, and has a good therapeutic effect on alcoholic liver damage.
- Anti-inflammatory and antioxidant activity
Both betulin and betulic acid have mild anti-inflammatory properties at higher concentrations, and their anti-inflammatory properties may depend on the inhibition of protein kinase C without involving any neurogenic inflammatory mechanism. Inflammation is closely related to many diseases, such as bacterial pneumonia, alcoholic lung injury, breast inflammation, myocardial protection, mouse foot injury, etc. Betulin can reduce myeloperoxidase activity and lung tissue bacterial load by inhibiting pro-inflammatory factors induced by LPS and Escherichia coli, thereby reducing LPS-induced acute lung injury.
- Protect hippocampal neurons
Buttiol can improve the depressive behavior of rats with chronic stress depression model and has a certain protective effect on their hippocampal neurons. Betulin protects synapses by increasing the expression of PSD-95 and Synapsin-I in the hippocampus, reducing the damage of oxidative stress to hippocampal neurons, improving the learning and memory abilities of APP/PS1 double transgenic dementia model mice, enhancing the long-term function of the hippocampus, and protecting the cognitive function of experimental animals.
What Are The Applications Of Betulin?
Betulin has anti-inflammatory, antiviral, inhibits protein dissolution in hair fibers, improves the gloss of damaged hair, and promotes hair growth.
It can be applied to food, cosmetics and medicine industries.
- Food field
Betulin, as a natural extract, has good biological activity and safety. It can be used as a food additive to provide natural preservation and freshness for food.
- Cosmetic field
Betulin is often used in skin care products and cosmetics due to its antioxidant and anti-inflammatory properties, which helps protect the skin from free radical damage and maintain skin health.
- Pharmaceutical field
Betulin has multiple biological activities such as anti-inflammatory, antioxidant, and anti-HIV. It can inhibit the proliferation of gastric cancer cells and induce cell apoptosis. It has a certain therapeutic effect on radiation-damaged mice, and has a protective effect on myocardial damage induced by doxorubicin. It can also improve the depressive behavior of rats with chronic stress depression model, protect hippocampal neurons, and improve the learning and memory ability of APP/PS1 double transgenic dementia model mice. These characteristics make betulin have important application value in the pharmaceutical industry.
In addition, betulin also has the effect of inhibiting the synthesis of cholesterol and triglycerides, and can effectively prevent obesity, atherosclerosis and type 2 diabetes. Although these properties may be relatively less used in the pharmaceutical industry, they are also part of the application areas of betulin.
The application of betulin not only reflects its important position in natural product research, but also provides new raw material options for the pharmaceutical and cosmetic industries. With the deepening of research, the application field of betulin will be further expanded.
