Abstract
A narrow baseline method for the simultaneous determination of pheophorbide a and methylpheophorbide a in core sediment samples has been developed by high performance liquid chromatography, A linear relationship between the concentration of methylpheophorbide a and the peak height on the narrow baseline was obtained. The relative standard deviation of measurement was found to be 2.4% (n=6) for samples containing 8.1 x10-8 mol dm-3 of methylpheophorbide a.
