ABSTRACT The objective of this work was to quantify the saponins present in the root of Medicago sativa L. by high-performance liquid chromatography (HPLC). The research was carried out in the Multifunctional Laboratory of the Faculty of Pharmacy and Biochemistry of the National University of Trujillo, using roots collected on the university campus. The roots were subjected to a drying, grinding and ethanolic extraction process. Qualitative tests of saponins (Rosell, Salkowski, Liebermann-Burchard) were performed. The physicochemical values of the root extract of Medicago sativa L. were determined, such as: pH 6.11, refractive index 1.36, total ash 3.3%, relative density 0.8 and acidity index 2.576 mg KOH. For quantification, a saponin standard (Quillaja saponaria) was used, constructing a calibration curve with concentrations in mg/mL vs the area under the curve, obtaining a linear regression equation with a correlation coefficient of R2 = 0.982. The results showed that the concentration of saponins in the sample was 0.13 g per gram of sample.
