Determination of natural colorants in plant extracts by

In the case of the indigo extracts, an optimized acid hydrolysis was applied. HPLC separations were performed on a Hypersil ODS RP18 column using linear gradient elution programs. The detection limits for 1–4 were 0.11, 0.6, 0.10, 0.089 μg mL-1, respectively. The procedure did not involve any sample "clean-up" methods.
