The optical isomers, shikonin and alkannin, can be separated by chiral phase high performance liquid chromatography. The results of analysis have shown that the commercial standards of "shikonin" or "alkannin" as well as the red pigments extracted from the roots of some Boraginaceous plants contain both optical isomers in various proportions.
