bixin
Also known as 6'-methyl hydrogen 9'-cis-6,6'-diapocarotene-6,6'-dioate, 6'-methyl hydrogen 9'-Z-6,6'-diapocarotene-6,6'-dioate, methyl (9-cis)-hydrogen-6,6'-diapo-psi,psi-carotenedioate
Bixin is an apocarotenoid found in the seeds of the achiote tree (Bixa orellana) from which it derives its name. It is commonly extracted from the seeds to form annatto, a natural food coloring, containing about 5% pigments, of which 70–80% are bixin.
