Development And Validation

A simple, accurate, precise, robust stability indicating RP-HPLC method was developed and validated for simultaneous estimation of berberine and curcumin in an ayurvedic formulation. The two markers were resolved using a C-18 column using as the mobile phase methanol: water (pH 3 adjusted using acetic acid) in the ratio 75:25 V/V at a flow rate of 1mL/min. Retention times of berberine and curcumin were 2.58 ± 0.2 min and 8.5 ± 0.2 min, respectively at 358 nm. Linear response was observed in the concentration range of 2 – 8 ppm for berberine and 5 – 40 ppm for curcumin, with correlation coefficient (r2) of 0.994 and 0.998 for berberine and curcumin, respectively. The developed method was applied for quantitation of markers in marketed and in-house formulations of Gruhadhoomadi Churna. This method can also be used to evaluate formulations containing berberine and curcumin as markers, thus conforming to the need of ensuring quality and safety of herbal medicines.

Development And Validation

A reliable, selective and sensitive stability-indicating RP-HPLC assay was established for the quantitation of bromazepam (BMZ) and one of the degradant and stated potential impurities; 2-(2-amino-5-bromobenzoyl) pyridine (ABP). The assay was accomplished on a C18 column (250 mm × 4.6 mm i.d., 5 μm particle size), and utilizing methanol-water (70: 30, v/v) as the mobile phase, at a flow rate of 1.0 ml min-1. HPLC detection of elute was obtained by a photodiode array detector (DAD) which was set at 230 nm. ICH guidelines were adhered for validation of proposed method regarding specificity, sensitivity, precision, linearity, accuracy, system suitability and robustness. Calibration curves of BMZ and ABP were created in the range of 1–16 μg mL-1 with mean recovery percentage of 100.02 ± 1.245 and 99.74 ± 1.124, and detection limit of 0.20 μg mL-1 and 0.24 μg mL-1 respectively. BMZ stability was inspected under various ICH forced degradation conditions and it was found to be easily degraded in acidic and alkaline conditions. The results revealed the suitability of the described methodology for the quantitation of the impurity (ABP) in a BMZ pure sample. The determination of BMZ in pharmaceutical dosage forms was conducted with the described method and showed mean percentage recovery of 99.39 ± 1.401 and 98.72 ± 1.795 (n = 6), respectively. When comparing the described procedure to a reference HPLC method statistically, no significant differences between the two methods in regard to both accuracy and precision were found.
