    corresponding anthocyanidins using paper chromatography‚ and spectrophotometric analysis procedures. Based on experimental data the blueberries contained the most amount of anthocyanins at 1.92 x 10-6 g‚ followed by blackberries at 1.19 x 10-6 g‚ finally followed by raspberries at 5.84 x 10-7 g. The paper chromatography data also supports the idea that blueberries contained the most anthocyanidins‚ since it contained the most streaks on the chromatography paper. The main conclusion that can be

    6. FIRST DERIVATIVE ZERO CROSSING METHOD 6.1. ABSTRACT: Simple‚ specific‚ accurate and precise 1st order derivative zero-crossing spectroscopic method was developed for simultaneous determination of PHENYLEPHRINE and EBASTINE from their binary mixture. In this 1st derivative zero-crossing spectroscopic method the amplitudes of the 1st order derivative of the spectra of the binary mixture containing PHE and EBS were measured at 252.2 nm (zero crossing of EBS) for determination of PHE and at 274.8

    . Yes‚ comparably to TLC plate 2 and 3. The benzophenone is more neutral but as the same time its nonpolar‚ being that Silica gel in TLC 2 was polar and the solvent ethyl acetate-hexane is non-polar it moved relatively with the solvent. The stationary phase in TLC 3‚ alumina is non polar and the solvent ethyl acetate is polar so from the ideal that polar does not attract non-polar benzophenone stick stronger to alumina non-polar rather than moving up with polar solvent ethyl acetate as it did in
