Box–Behnken design avenue for development and validation of high-performance thin-layer chromatography method for estimation of rutin in Hemidesmus indicus Biomedical Chromatography (IF1.902), Pub Date : 2021-09-01, DOI: 10.1002/bmc.5236 Suman Shrivastava, Sanjay J. Daharwal
The aim of this study was to determine the content of rutin in Hemidesmus indicus and to optimize the high-performance thin-layer chromatography method. The method was validated in compliance with the International Council for Harmonisation guidelines Q2 (R1) for parameters such as linearity, accuracy, precision, robustness, limit of detection, and limit of quantitation. A Box–Behnken design and response surface methodology has been used to investigate the impact of independent variables on the response. Three independent variables, mobile phase composition (% v/v), mobile phase volume (mL), and duration of saturation (min), were studied. Rutin was verified, and its content was determined using a validated high-performance thin-layer chromatography method with good linearity within the range of 200–1000 ng spot–1 with r2 = 0.9998 and correlation coefficient with calibration curve equation y = 0.0297x + 0.0001. The average percentage recovery values varied from 99.03 to 101.15 and 98.88 to 100.12%, respectively, for in-house and marketed mother tincture). The peak area determination at three different concentration levels shows low values of percentage relative standard deviation (<2%) for inter-day (0.04–0.06) and intra-day (0.04–0.05) precision of rutin. The average content of rutin in extract and marketed mother tincture was 229 ± 0.57 and 210 ± 0.57 μg g–1. The proposed method was simple, precise, and accurate for the determination of rutin with frequent quality control assessment of H. indicus.
