Structure of three new carotenoids with a 3-methoxy-5-keto-5,6-seco-4,6-cyclo-beta end group from the seeds of Pittosporum tobira.
Three new carotenoids with a 3-methoxy-5-keto-5,6-seco-4,6-cyclo-beta end group (1-3) have been isolated from the seeds of Pittosporum tobira. Their structures were elucidated by detailed analyses of nuclear magnetic resonance and UV data.
