Advances and Challenges in the Analysis of Boswellic Acids by Separation Methods.

resin is an exudate from the cut bark of trees. The main constituents of pharmacological interest are boswellic acids (pentacyclic triterpenoids), namely α-boswellic acid, β-boswellic acid, 3--acetyl-α-boswellic acid, 3-acetyl-β-boswellic acid, 11-keto-β-boswellic acid, and 3--acetyl-11-keto-β-boswellic acid. Nowadays, dietary supplements with extract are used in the treatment of inflammatory joint diseases.
