Chem Pharm Bull (Tokyo). 2006 May;54(5):690-2. doi: 10.1248/cpb.54.690.

Abstract

From the seeds of Annona glauca and A. cherimola, two novel cyclic peptides, glaucacyclopeptide B and cherimolacyclopeptide G, have been isolated, respectively. Their structures were elucidated by chemical and spectral methods.
