Studies on the Microanalysis of Essential Oil Components. V. Detection of Essential Oil Components by Paper Electrophoresis.

抄録

Extensive studies were made for the detection of terpene alcohols, aldehydes, ketones, and lactones by paper electrophoresis. The method is generally available for a rapid test of perfume products and it could be accomplished more rapidly than chromatography on paper by using a current of 500∼8, 000 V, reported previously. The higher the voltage, the sooner the results are obtained in electrophoresis, while a constant time was required in chromatography owing to the constant capillarity of the filter paper itself. One of many electrolytes applied, mercuric chloride, has shown the most satisfactory result and a formation of conjugated carbonyl groups with mercuric ion was presumed.
