Abstract
A simple process has been developed for the isolation of a natural dye from the stems of Sorghum bicolor (L.) Moench subsp. americanum cauda tum. The process, with a yield of 20% dry material, can be extrapolate d to an industrial scale for use in the food and cosmetic industries. The composition of the dye was elucidated by high-performance liquid c hromatography, which identified a major anthocyanidin (apigeninidin, 1 7% of the extract) and two main flavonoids (luteolin and apigenin, 9 a nd 4%, respectively). The absence of the corresponding flavonoid gluco sides was confirmed.
