A method of auxin extraction is discussed in which frozen plant material is ground, then boiled for one minute to destroy the enzyme system responsible for the formation of the active growth hormone from a precursor during the extraction period. This boiling for one minute is not destructive to the auxin, which is then extracted from the tissue with ether in the usual way.
