| Sumario: | <i>Mondia whitei</i> is one of the popular medicinal plants in Africa, which has been used extensively across the continent to cure various ailments. Products prepared from this plant are distributed commercially. In this study, an HPLC-DAD method was developed and validated for seven compounds to enable quality control of these products. The method was validated using the external standard-calibration and the standard-addition methods which were found not significantly different. The method was found to be linear in the ranges 1–14 mg/L and 3–14 mg/kg with correlation coefficients from 0.9942–0.9995 and 0.9907–0.9993 in the solvent and the different matrices, respectively. The limit of detection (LOD) values of the method were found to range between 0.1–1.2 mg/L in the solvent and syrup, and between 0.4–1.2 mg/kg in the teabag and root powder. The limit of quantification (LOQ) values were found to range between 0.5–3.9 mg/L in the solvent and syrup, and between 1.4–3.8 mg/kg in the teabag and root powder. The method was also found to be precise with percentage relative standard deviations below 5% and 10% in the solvent and matrices, respectively. The method was applied to <i>Mondia whitei</i> products for qualitative and quantitative analysis. |
