Abstract
The biological activity of naturally occurring boswellic acids in specific plant extracts is enhanced by their peracetylation, preferably followed by silica gel treatment, or by peracetylation and mild oxidation to increase the ratio of 3-β-acetyl-11-keto-β-boswellic acid to β-boswellic acid, 3-β-acetyl-β-boswellic acid and 11-keto-β-boswellic acid. The enriched compositions compared to the commercial extracts have enhanced biological activity toward a variety of proliferative and/or inflammatory afflictions in mammalian hosts and demonstrate synergism with other phytochemicals.
Claims48

- administering to said mammalian host a therapeutically effective amount of a composition or its physiologically acceptable salts, prepared according to the method comprising:
- peracetylating a Boswellia serrata pentacyclic terpene acidic fraction extract to provide a peracetylated product having a ratio of AKBA to the other boswellic acid components in boswellin increased compared to said acidic fraction.
A method for enhancing the therapeutic activity of the pentacyclic acidic fraction from Boswellia serrata, said method comprising:
- peracetylating said acidic fraction with an acetylating agent to provide a peracetylated product;
