  • Chromatography of Photosynthetic Pigments | Lab Report

    The principles of chromatography as used today have as their starting point the botanist Michael Tswett (1872 – 1919). In 1906 he published a procedure involving the separation and isolation of yellow and green colours of leaves by chromatographic absorption. Methods: Firstly, the leaf extract was prepared by weighting out 3 g of fresh ...

    21/04/2017 · Chromatography of Plant Pigments INTRODUCTION: Chlorophyll often hides the other pigments present in leaves. In Autumn, chlorophyll breaks down, allowing xanthophyll and carotene, and newly made anthocyanin, to show their colors. The mix of pigments in a leaf may be separated into bands of color by the technique of paper chromatography.
