- A cell strain originally derived from floral meristem tissues of Carthamus tinctorius (dyer’s saffron) produced substantial amounts of a novel red pigment under controlled culture conditions. The pigment isolated f r om alcoholic extracts of C. tinctorius cultures was compared with authentic carthamin, anthocyanins, betain, and carotenoids. It differed markedly from carthamin and showed none of the characteristic properties of the glycoside or chloride forms of authentic delphinidin, cyanidin, and pelargonidin. Analytic data indicated that this pigment also differs from betanin and from α- and β-carotene. The name “Kurenamin” was tentatively given to this newly isolated red pigment. Effect of the culture media, micro-elements, macro-elements, and putative substrates on the kurenamin production were investigated during cell suspension culture.
