Biotransformation of Safflower Yellow B to Carthamin, A Coloring Matter of Safflower

Abstract

Abstract Safflower yellow B, one of the yellow coloring components of safflower (Carthamus tinctorius L.), was transformed to red carthamin and safflomin-A in cultured safflower cells. This result suggests that carthamin and other yellow coloring matters are biogenetically derived from safflower yellow B in the florets of safflower.
