 Title    Accumulation of a Novel Red Pigment in Cell Suspension Cultures of Floral Meristem Tissues from Carthamus tinctorius L  
 Abstract    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 from 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 a-and ß-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.

 Title    Acceleration of Enzyme-Dependent Carthamin Formation by Manganese with Diversed Valence States  
 Abstract    Effect of manganese with three different valence states on carthamin formation was studied by using freshly collected flowers from dyer's saffron (C. tinctorius) capitula. A t 1 -10 hm con­ centration, these cations accelerated markedly the carthamin formation induced by endoge­ nous enzyme(s) in the detached floral tissues. The acceleration was obviously dependent on the valence state o f the test metals, more pronounced by M n (V II) or M n (III) than by M n (II) at a series o f given ionic strengths. O n a 1 |aM level, M n (V II) and M n (III) accelerated the pigment accumulation by faster o f 9 and 8, resp. than M n (II) during 5 min incubation at 30 °C. M n (V II) and M n (III) acted on both fresh and boiled florets, while M n (II) exerted preferential­ ly its activity on intact materials. Possible im plication of manganese ions on the enzyme-cata-lyzed carthamin formation are discussed.

 Title    Kinobeon A, A Novel Red Pigment Produced in Safflower Tissue Culture Systems  
 Abstract    The production of safflower pigments by tissue culture techniques was carried out using the calh induced from various parts of the plant. After massive cell selection efforts, a cul­ ture cell line (KB 7) was found to produce a considerable amount of a red pigment. Addi­ tion of cellulose powder and D-phenylalanine into the medium dramatically improved the pigment production. After purification, red crystals were obtained. Its UV/VIS spectrum as well as the HPLC behavior was clearly different from that of carthamin found in the mother plant and those of another typical plant pigments, suggesting that it was a novel compound. Therefore, this pigment was named kinobeon A.
