Detection of shikonin and its derivatives in the GL and RR lines of the three Lithospermeae plants (i.e., Lithospermum erythrorhizon, Arnebia euchroma and Echium plantagineum) by HPLC. (a) The ethanol extracts from the above three Lithospermeae plants, (b) standards, (c) LeGL, (d) LeRR, (e) AeGL, (f) AeRR, (g) EpGL, (h) EpRR; 1. Shikonin, 2. Acetylshikonin, 3. Deoxyshikonin, 4. Isobutylshikonin; 5. β, β’-Dimethylacrylshikonin, 6. α-Methyl-n-butyrylshikonin/Isovalerylshikonin (isomerized products can not be separated in this study). * β-Hydroxyisovalerylshikonin (inferential). #Unknown compound.
