Betulinic Acid Powder for Dietary Supplement Ingredients
Overview
Betulinic acid is a naturally occurring pentacyclic triterpenoid widely found in the bark of birch trees, particularly Betula species. It can also be isolated from other plant sources, although birch bark remains the primary commercial raw material. As a plant-derived monomer compound, betulinic acid is recognized for its defined chemical structure and standardized purity.
Industrial production of betulinic acid typically involves extraction from birch bark followed by purification processes such as solvent extraction, filtration, and crystallization. These steps are designed to isolate the target triterpenoid and achieve a high-purity final product. Commercial material is commonly standardized to 98% purity, verified using high-performance liquid chromatography (HPLC).
The finished ingredient is generally supplied as a white or off-white crystalline powder with consistent physicochemical characteristics. Due to…
