By using GC/MS, the process of oxidizing reaction of atractylone is studied, and five decomposition products are obtained, which is greatly different from the references-only two decomposition products, and the mechanism of oxidizing reaction of atractylone is investigated. The hypothesized mechanism of reaction is: atractylone is readily to additively react with water and to generate the semiacetalhydroxyl at 1, 4-site.

We make chloroacetylaion to N-terminal of Asp, and then convert this compound to GD dipeptide by aminolysis. Followed the lipase -catalyzed peptide synthesis of RGD in aqueous water-miscible organic cosolvent is studied. We set up a new efficient reaction method to synthesize RGD tripeptide. The problem that peptide containing polar amino acid can not be synthesized readily in organic solvent was solved. We offer a new experimental proof for PPL-catalyzed peptide synthesis and make a more general analysis for the effect of some factors in theory.
