A study has been made of the effects of solvent, temperature, and the antioxidant, sodium diethyldithiocarbamate, on the breakdown of indole‐3‐pyruvic acid to indole‐3‐acetic acid (IAA). In addition, the degradation of tryptophan, tryptamine, indole‐3‐pyruvic acid, indole‐3‐acetaldehyde and indole‐3‐ethanol to IAA during the purification and analysis of extracts from Pinus sylvestris L. needles, in the presence and absence of sodium diethyldithiocarbamate, has been investigated. The data obtained indicate that if the antioxidant is supplied throughout the analytical sequence there is a marked reduction in the spontaneous formation of IAA from other indolic compounds and, by inference, the stability of indoles in general is enhanced.
