Determination of Bromide from Bacopa Monnieri (Brahmi) and Other Herbal Plants by Ion Chromatography

An Ion Chromatography method using suppressed conductivity detection for the quantitation of Bromide from Bacopa Monnieri (Brahmi) and other Herbal plants was developed and validated. Separation of Bromide from other anions was done using high capacity anion exchange column with a flow rate of 1.0ml/min. The calibration curve of standard Bromide showed good linearity of more than 0.999 of the correlation coefficient. The Limit of Detection and Quantification was 0.008mg/L & 0.028mg/L respectively. The relative standard deviations of intra and inter day analysis of Bromide was less than 3.0 %. The proposed method was successfully applied to determine Bromide in various herbal plant extracts which are available at local market in India.
