Abstract

Cyclic peptides were characterized using ESI/Ion Trap, ESI/Q-TOF, and MALDI/TOF mass spectrometry. The cyclic peptides were extracted from Pseudostellaria heterophylla and Brachystemma calycinum using ethyl acetate. A digestion with carboxypeptidase was also performed to verify the cyclic nature of the peptides. It was found that MALDI/TOF in conjunction with CID generates the best sequence coverage.
