About Birch Bark Extract
Birch Bark Extract is an active component isolated from the bark of birch trees, mainly containing betulin and betulinic acid, along with other components such as triterpenoids and flavonoids. We mainly provide birch bark extract products with specifications of 80%, 98% betulin content and 98% betulinic acid content, and can also offer customization according to different customer requirements.
Birch bark extract possesses multiple effects including anti-inflammatory, antibacterial, antioxidant, promoting skin repair and assisting in regulating body metabolism, thus it has broad application prospects in the fields of pharmaceuticals, skincare products and health products.

Betulin
Betulin is a natural compound, specifically a lupane-type triterpene, found abundantly in the bark of birch trees and other plants. It is known for its antibacterial, antioxidant, and skin-regenerating properties, making it useful in the cosmetic and food industries as a natural alternative to synthetic ingredients.
Betulinic Acid
Betulinic Acid is a naturally occurring pentacyclic triterpenoid found in plants like birch bark, known for its potential anticancer properties, and for exhibiting anti-inflammatory, anti-HIV, and antimalarial effects.

Contact us Extraction Source Advantages
1. Safe and Natural Birch Bark
No pesticides or chemical fertilizers are artificially applied during the growth of birch bark, making the raw material naturally pollution-free. The extracted products meet the strict safety standards of industries such as pharmaceuticals, cosmetics and food. Meanwhile, the loose fiber structure of birch bark allows easy dissolution of active ingredients during extraction, reducing solvent usage and further enhancing the safety of the products.
2. Abundant Resources and Easy Accessibility
Birch trees are widely distributed in Northeast China, North China and other regions, with sufficient resource reserves, enabling stable and continuous supply of raw materials to ensure the efficient operation of the production chain. At the same time, the mature and standardized raw material collection process allows quick response to order demands, avoiding delivery delays caused by raw material shortages.
3. Strong Environmental Sustainability
When we use birch bark as raw material, we obtain it through methods such as rational thinning and collection of naturally shed bark, without felling entire trees. This causes minimal damage to the ecological environment and aligns with the global trend of green development. Additionally, the waste generated during the birch bark processing can be recycled (e.g., made into biomass fuel), realizing resource recycling and reducing environmental burdens.
