Estimation of bulk drug and their formulations by analytical reagents by various methods. A review

Abstract

The  aim  of  present  work  is  to  find  out  a  simple,  specific,  and  spectrophotometric Methods  which  were developed for the detection of different pharmaceutical dosage forms using analytical and chemical reagents in bulk drug and their pharmaceutical formulati on. The developed methods have been  explained with the principle & reaction  in detail .The method were  ascertained by actual determination of fixed concentration of the drug with  in  Beer  -Lambert     range  .Hence  in  present  work  different  reagents  like   MBTH,  PDAB,  2,6- dichloroquinone, Folin  ciocalteaus, 1,10-phenanthroline, 2,3,5-triphenyl tetrazolium are  enlisted along with their estimated drugs.
