## Abstract The kinetics of oxidation of indoleβ3βacetic acid (IAA) by peroxodisulfate (PDS) has been carried out in aqueous acetic acid medium. Firstβorder dependence of rate each with respect to [IAA] and [PDS] was observed. The reaction rate was unaffected by added [H^+^]. Increase of percentage
Eleven indole derivatives of biological significance were added to an extract of etiolated pea seedlings and the mixture was separated on a column of Sephadex G-15, by the following sequence of eluants: ethylenediamine-acetate, pH 4.2, ethylenediamine-acetate, pH 7.4, distilled water, and a methanol
