Abstract
A colorimetric method has been developed for the quantitative determination of the rescinnamine, reserpine upto (-10(-4M)), Yohimbine on complexation with bromothymol blue. The coloured complexes exhibit absorption maxima in the region 415-416 nm. The RSD (Relative Standard Deviation) of the method is 2.02%. The method is simple, easy, rapid and convenient for routine analysis of the indolic drugs.
