Abstract
Two novel C-69 carotenoids containing an cl-tocopherol moiety, named pittos porumxanthins Al (1) and A2 (2), have been isolated from the seeds of Pitto sporum tobira. Their structures were elucidated by NMR and CD spectral anal ysis and chemical means. (C) 2001 Elsevier Science Ltd. All rights reserved .
