Abstract
Stowe and Thimann1 reported that they had isolated indolepyruvic acid from maize endosperm by paper chromatography. They used the methods of ammoniacal chromatography. However, Bently2 found that under these conditions synthetic indolepyruvic acid breaks down into a number of compounds. Moreover, in a recent paper by Kaper and Veldstra3, it was shown that both synthetic and isolated indolepyruvic acid break down when chromatographed in a basic solvent. Srivastava4 has also obtained results similar to that reported by Kaper and Veldstra.
