Analysis of Plant Pigments from Various Sources

Discovery Experiment Analysis of Plant Pigments from Various Sources [Pg.186]

Investigate the distribution of pigments obtained from other sources of green leaves, such as beets, chard, trees, and shrubs. Avoid the use of waxy leaves, as their coating makes extraction and isolation of the pigments more difficult. [Pg.186]

Put the unused eluants containing only petroleum ether, acetone, and ethanol in the container for nonhalogenated organic liquids and any unused eluants containing chloroform in the container for halogenated organic liquids. Discard the dry chromatographic plates in the nonhazardous solid waste container. [Pg.186]

Purpose To identify solvent mixtures that will separate syn- and anf/-azobenzenes using thin-layer chromatography. [Pg.186]

Petroleum ether, ethanol, and acetone are highly volatile and flammable solvents. Be certain there are no flames in the vicinity during this experiment. [Pg.186]
