A spectrophotometric method has been developed for the quantitative determination of indole drugs, i.e., yohimbine, reserpine and rescinnamine on complexation with iodine. The coloured complexes exhibit absorption maxima in the region 360-369 nm. The RSD( Relative Standard Deviation) of the method is 2.0%. The method is simple, rapid and convenient for routine analysis of the drugs.
