Extraction of Betulin and Betulinic Acid from Birch Bark

NaturNorth has created bioactive compounds with potential applications in pharmaceutical, agricultural, and biocidal applications. The compounds have potential applications against HIV, MRSA, herpes, in anticancer treatments, and in anti-inflammatory, liver protection, and skin protection applications. The compounds are derived from betulin and betulinic acid, naturally occurring substances found in the bark of the birch tree. To obtain betulin and betulinic acid, NaturNorth developed cost-effective ways of extracting the substances from the bark (a low-cost renewable resource). There are three primary assets of value: An existing library of 1,000 proprietary, protected, and confidential compounds; the capability to export a “mine” of new potential compounds; and the source of low-cost production through extraction of betulin from birch bark and proprietary synthesis methods for derivatives.
