Abstract:
Safflower, used since ancient times, contains two C‐glycosidic main dyes, the water soluble Safflower yellow A (Hydroxysafflower yellow A) and the red Carthamin, which is water insoluble, but can be dissolved in the alkaline. Properties of both quinochalcone dyes are compared and also with other glycosidic dyestuffs. The biosynthesis of safflower is described as well as chemical syntheses. A few recipes for own dyeing are given. The present renaissance of Safflower is, however, not due to its dyes, but to safflower oil, a nutritionally valuable vegetable oil. We report on the isolation of Safflower yellow A and the fight for Carthamin. The complete set of analytical spectra together with interpretations is presented for Safflower yellow A. Background information complements the matter.
