Development of general approaches to spectrophotometric determination of phenolic compounds in medicinal plant raw materials and related pharmaceutical formulations.

Regularities of spectrophotometric determination of phenolic compounds in medicinal plant raw materials are considered taking into account the effect of coexisting compounds. An algorithm for the development of a spectrophotometric procedure of analysis of biologically active compounds in medicinal plant raw materials and related pharmaceutical formulations was composed on the basis of generalized results of author´s own studies and literature data.
