  • The characteristics of the pigments extracted from grains of the colored barley varieties Ab2231, Mozzimugi, Lion, and Hogye 4 were studied. Extraction of the pigments from powder (80 mesh) of the barley grains was most efficient in 80% ethanol containing 1.0% HCI for 1 hr at $60^{\circ}C$. The pigments were also stable in 80% ethanol containing 1.0% HCI. Depending on the absorption spectra, maximal peak wavelength, and the ratio of $A_{440}/A_{max}$, the varieties were separated into two groups, colored naked barley (Ab2231 and Mozzimugi) and colored covered barley (Lion and Hogye 4).
