Qualitative Analysis of the Constituents of an Unknown Natural Product
In chemical studies of natural products the first question the investigator wants to know is which commonly occurring constituents of natural products are present in the preparation. Qualitative analysis has to precede quantitative studies because it demonstrates not only the absence or presence of certain detectable components, but also gives information about the relative amounts of constituents present in the preparation. The presence of unusual components in hydrolysates investigated by paper electro-phoresis or paper chromatography has led in the past to the discovery of many new compounds.
