| Abstract: | A method for quantitative analysis of shikonin derivatives using high pressure liquid chromatography (HPLC) was established. With this method the composition of shikonin derivatives in cultured cells and roots of Lithospermum erythrorhizon (ko-shikon) was compared. The composition of shikonin derivatives produced by cell suspension cultures was similar to that of the ko-shikon, and the composition in cultured cells was found to fluctuate less than that of the ko-shikon. |
