  Abstract:  A kinetic method for separate determination of B1, B2 and B6 vitamins has been proposed. It is based on the Landolt type system of redox reactions, is very sensitive, cheap and make use of simple technique. Calibration lines have been obtained under appropriate conditions. Good detection limits as well as good accuracy and precision were found. Some interference of various organic compounds and metal ions have been investigated. The method has been tested to several pharmaceutical products yielding results similar to the certified content given by producers.
