Red and yellow colorants from the safflower florets (Carthamus tinctorius L., Compositae) are applicable to processed foods and soft drinks as color additives, cosmetic rouge, dyes, and medicine [Meselhy et al., 1993]. Almost all of these red and yellow colorants in the petals of safflower are classified as members of the C-glucosylquinochalcone family of flavonoids that occurs only in C. tinctorius [Kazuma et al., 2000]. A red colorant of the safflower, carthamin, is composed of two C-glucosylquinochalcone moieties [Obara and Onodera, 1979].
