Abstract
The separation of color pigments of chili powder was performed on various narrow bore HPLC columns (octadedecylsilica, silica, and polybutadiene coated alumina) using gradient elution and, the retention characteristics of the columns were compared. The separation capacities of silica and polybutadiene coated alumina were lower than those of other columns. The highest number of fractions were separated of octadecylsilica columns, however, the efficiency of the column depended considerably on the type of C18 coating, proving the marked influence of coating process on the separation capacity.
