Structure of new carotenoids from corbicula clam Corbicula japonica.
Six new carotenoids, named corbiculaxanthin (1), corbiculaxanthin 3'-acetate (2), 6-epiheteroxanthin (3), 7',8'-didehydrodeepoxyneoxanthin (4), cyclopyrrhoxanthin (5), and hydratoperidinin (6), were isolated from the corbicula clam (Shijimi in Japanese), Corbicula japonica. Their structures were determined by chemical and spectral data.
