Three 5-hydroxy-seco-carotenoids were isolated from seeds of Pittosporum tobira. These structures were determined to be (3S,3'S,5'?)-3,3'-di(tetradecanoyloxy)-5'-hydroxy-5,6,5',6'-diseco-beta,beta-carotene-5,6,6'-trione (1), (3S,5?,3'S,5'R,6'S,9'Z)-3-tetradecanoyloxy-5',6'-epoxy-5,3'-dihydroxy-5',6'-dihydro-5,6-seco-beta,beta-caroten-6-one (2), and (3S,5?,3'S,5'R,6'R)-3-tetradecanoyloxy-5,3',5'-trihydroxy-6',7'-didehydro-5',6'-dihydro-5,6-seco-beta,beta-caroten-6-one (3) based on analysis of UV-vis, IR, FAB MS, and NMR spectroscopic data.
