✦ Synopsis

Swertiamarin and gentiopicroside were quantified simultaneously using thin layer chromatography (silica gel) with densitometry (240 nrn). The single calibration graph was linear in the interval 1.0-16.0 pg in the presence of an external standard. The standard deviation did not exceed 5% and the relative error varied in the range 0 . 5 4 % . The procedure was applied to determine these iridoids in ten samples of Centuurium erythrea and C. turcicum from various regions in Bulgaria.
