BACKGROUND: The prescriptions of multi-component have been the subject of chemical study fora long time. Therefore, when compounding the preparations of multi-component in traditionalmedicine, their taste is cautiously relied on, as the power of the medicine should not be subduedwith the power of another. Our research group has been carrying out tests on the raw materials,which are contained in multi-component prescriptions. However, research on multiple prescriptionsis relatively less being carried out.The traditional medicine naro-3 is used in traditionalmedical practicefor the treatment of inflammationand as a pain relieving remedy. Naro-3 is composed of 3 medicinal herbs including AconitumKuznezoffii Reichb, Terminalia chebula Retz, Piper longum L.GOAL: The aim of the study is to investigate some phytochemical compounds of traditional prescriptionNaro-3.OBJECTIVES:1. To reveal biological active substances of naro-3;2. The sum of the quantitative chemical study by spectrophotometry;3. To establish main criteria of standardMATERIALS AND METHODS: Traditional medicine narî-3 was produced from the Traditional Medicinefactoryof TMSTPC. In the phytochemical research, biological active substances were determinedby thin layer chromatography (TLC), on silica gel plats. The total contents of alkaloid and tannincompounds were determined by titrimetric method. TheMongolian pharmacopoeia was used fordetermination of quality parameters of traditional medicine Naro-3.RESULTS: TLC measurements of biological active substances of naro-3 showed that contains gallicacid and alkaloids respectively. The result of our research it was determined that the total tannin10.4 percent, total alkaloid 2.47 percent and organic acid 2.67 percent in drug Naro-3.CONCLUSION: The results of the study indicate that naro-3 contains a large amount of biologicalactive substances such as tannins, alkaloids and organic acids, which are connected with its painrelieving and anti-inflammatory effects.
