Pheromones purification methods

The nature of functional groups in a pheromone can be determined by chemical modification coupled with a sensitive bioassay of the converted material. For example, if a pheromone loses activity after saponification and regains it upon acetylation it likely contains an acetate group. Loss of activity after hydrogenation indicates unsaturation. Inscoe and Beroza (IS) tabulated many of the typical functional group tests that can be used in pheromone structure elucidation. These tests need not be restricted to purified material they can be employed on crude extracts as well and the results may suggest purification methods to be used (or avoided). [Pg.11]

One of the simplest methods of purification involves crystallization of synthetic intermediates (and sometimes of the pheromone itself) at low temperature. This technique has been extensively used in the purification of fatty acids, 9). Like unsaturated fatty acids, many of the related alcohols are very insoluble in hydrocarbon solvents at low temperature. [Pg.28]
