Abstract
Four cyclic peptides were isolated from young unshiu (unripe fruit), orange and amanatsu peelings, and their structures were established on the basis of FAB-MS (CID method) and 2D-NMR spectroscopic data, and by chemical evidence. They were each found to consist of seven or eight amino acids.
