Eleven apocarotenoids (1-11) including five new compounds, 4, 6, 9, 10 and 11, were isolated from the fruits of the red paprika Capsicum annuum L. The structures of new apocarotenoids were determined to be apo-14'-zeaxanthinal (4), apo-13-zeaxanthinone (6), apo-12'-capsorubinal (9), apo-8'-capsorubinal (10), and 9,9'-diapo-10,9'-retro-carotene-9,9'-dione (11) by spectroscopic analysis. The other six known apocarotenoids were identified to be apo-8'-zeaxanthinal (1), apo-10'-zeaxanthinal (2), apo-12'-zeaxanthinal (3), apo-15-zeaxanthinal (5), apo-11-zeaxanthinal (7), and apo-9-zeaxanthinone (8) which have not been previously found in paprika. These apocarotenoids were assumed to be oxidative cleavage products of C(40) carotenoid such as capsanthin in paprika.
从红辣椒（辣椒属）果实中分离出11种类胡萝卜素（1 - 11），包括5种新化合物，即4、6、9、10和11。通过光谱分析确定新类胡萝卜素的结构为脱辅基-14'-玉米黄质（4）、脱辅基-13-玉米黄质酮（6）、脱辅基-12'-辣椒玉红素（9）、脱辅基-8'-辣椒玉红素（10）和9,9'-二脱辅基-10,9'-反式-胡萝卜素-9,9'-二酮（11）。另外6种已知类胡萝卜素被鉴定为脱辅基-8'-玉米黄质（1）、脱辅基-10'-玉米黄质（2）、脱辅基-12'-玉米黄质（3）、脱辅基-15-玉米黄质（5）、脱辅基-11-玉米黄质（7）和脱辅基-9-玉米黄质酮（8），这些在辣椒中未曾被发现过。这些类胡萝卜素被认为是辣椒中类胡萝卜素（如辣椒红素）的氧化裂解产物。
