摘要：

Field desorption mass spectroscopy has identified five phencyclopeptines in the crude alkaloidal extracts of Ceanothus sanguineus. A new paired-ion hplc system for the separation of these alkaloids in discussed. Amino acid analysis, electron impact mass spectroscopy, and 1H nmr spectroscopy have established the the structures of six phencyclopeptines including two isomeric compounds 5 and 6. The structure of 2 has not been previously reported. © 1979, American Chemical Society. All rights reserved.
