title: Spectrophotometric method of determination of natural indoles by coloured complexes.
abstract: A new spectrophotometric method has been developed for quantitative determination of naturally occurring indoles via electron donor-acceptor complexes with chloranil. The method is simple, precise and convenient for routine laboratory work. The analysis of each indole can be carried out within half an hour.
