Abstract

A new colour pigment fraction was detected in Capsicum annuum by high performance liquid chromatography. Surprisingly the pigment was strongly bound both to silica and octadecylsilica surfaces indicating that its molecular mass is probably high. Peak purity tests proved that the fraction is not homogeneous and the degree of inhomogeneity depends on the wavelength used for the peak purity test. The spectra taken at one minute intervals of the peak were strikingly different supporting the above conclusions. It is possible that this highly lipophilic pigment is a secondary product of the ripening and processing procedures and is a mixture of individual pigments covalently bound to each other.
