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.
从温州蜜柑（未成熟果实）、橙子和甘夏果皮中分离出四种环肽，并根据快原子轰击质谱（碰撞诱导解离法）、二维核磁共振光谱数据以及化学证据确定了它们的结构。发现它们各自均由七个或八个氨基酸组成。
