Standardization of Adhatoda vasica Nees Market Preparations by RP-HPLC Method
Keywords:Standardization, Quality control, Adhatoda vasica Nees, Vasicine, RP-HPLC
In recent times, quality control of herbal and traditional medicines with modern scientific techniques and knowledge are of great concern. The present study reveals a simple and improved reversed phase HPLC method for qualitative analyses of Adhatoda vasica Nees market preparations via quantitation of its major metabolite, vasicine as a marker compound. Three market preparations, each of four different herbal and traditional manufacturers, were analyzed. The market preparations were extracted with chloroform and the residue obtained from extraction of each market preparation was analyzed for quantitation of vasicine by RP-HPLC method with ODS column using a mixture of water and methanol (60:40) as mobile phase at a flow rate of 0.5 ml/min. The estimated quantities of vasicine compared to reference standard for marketed products of four different manufacturers were found to be 1.502 ± 0.064 g, 1.590 ± 0.081 g, 1.761 ± 0.061 g and 1.627 ± 0.082 g, respectively per 100 ml of preparation.
