Abstract
Five apocarotenoids were isolated in trace amounts from the seed coat of the Bixa orellana L. fruits. Their structures were established by m eans of UV-visible, 400 and 500 MHz H-1 and 100 and 120 MHz C-13 NMR s pectroscopy, and mass spectrometry, Methyl (7Z,9Z,9'Z)-apo-6'-lycopeno ate, methyl (9Z)-apo-8'-lycopenoate, methyl (all-E)-apo-8'-lycopenoate are new carotenoids, and the other two, methyl (all-E)-8'-apo-beta-ca roten-8'-oate and methyl (all-E)-apo-6'-lycopenoate, have not been pre viously found in annatto.
