Especially after primary distillation, the high volatile components of 1-decanol and α-terpineol, which were of the highest relative conten t, were remarkably declined, even could not be found. The volatile constituents were also lost after rectification. Some constituents with weak volatility were lost because of the excipient, cosolvent and filtration.

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.
