Abstract
From the seed coat of Bixa orellana fruits, six minor carotenoids and one C-14-carotenoid derivative were isolated by chromatography (CC, TL C, HPLC) and their structures elucidated by means of spectroscopy (UV- visible, MS, H-1 and C-13 NMR). Dimethyl (9Z,9'Z)-6,6'-diapocarotene-6 ,6'-dioate, methyl (9Z)-10'-oxo-6,10'-diapocaroten-6-oate, methyl (9Z) -6'-oxo-6,5'-diapocaroten-6-oate and methyl -4,8-dimethyl-12-oxododecy l-2,4,6,8,10-pentaenoate are new compounds, whereas methyl bixin and m ethyl (9Z)-8'-oxo-6,8'-diapocaroten-6-oate have previously been found in annatto.
