Habb-e-Irqun-Nisa (HINa) is a well-documented poly-herbal formulation in Indian System of Medicine (Unani System of Medicine). It is extensively used to treat arthritis, sciatica and gout. A rapid, simple, sensitive, robust, economic and improved RP-HPLC coupled with dual λ absorbance-detector method was developed and validated for estimation of three therapeutically bioactive marker compounds, namely gallic acid, aloin and colchicine in the poly-herbal preparation, HINa. The chromatographic separation was achieved in less than 25 min by RP-HPLC (C18 column, 5.0 µm, 4.6 mm x 250 mm, Waters,) at a column temperature of 30 °C with gradient elution using acetonitrile and water (20 mM ammonium acetate) with a flow rate of 1.0 mL/min and UV-detector at λmax 287nm for 0 – 7 minutes and 360nm for 8 – 25 minutes. The results were achieved with respect to repeatability (RSD < 3.4%) and recovery (98.1 – 100.8%). The method was validated for linearity, accuracy, repeatability, LOD, and LOQ. The robustness of this method was also evaluated on the small fluctuations of pH in the mobile phase, the mobile phase compositions, temperature of column and the flow rate. The results indicated that the developed analytical RP-HPLC method could be a useful tool for quality control and standardization of HINa.
