Abstract
AN earlier paper1 described a method for separating a number of indole derivatives and auxin-like substances in plant extracts, using silica-gel partition columns and petroleum ether: n-butyl alcohol solvents used with a step-wise elution technique. Further investigations, the results of which are reported here, have extended this technique to include a number of other useful solvent mixtures.
