title: Spectrophotometric determination of natural indoles by complexing with 1,3,5-trinitrobenzene.
abstract: A spectrophotometric method has been developed for the quantitative determination of some natural indoles by complexing with the electron acceptor 1,3,5-trinitrobenzene and measuring the absorbance in the region 460-529 nm. The RSD of the method is 2.5%. It is simple, rapid and convenient for the routine analysis of indole compounds.
