“Extracción de alcaloides presentes en las semillas de lupinus mutabilis y su actividad antibacteriana”

Abstract

Lupinus mutabilis is a plant with high nutritional properties and high agronomic potential derived from the protein content of its seeds and growing conditions in the soil. This plant biosynthesizes different secondary metabolites with antioxidant and antibacterial properties, making it potential for the development of antibacterial products. Due to the above, this research aims to extract alkaloids present in Lupinus mutabilis seeds grown in Valle del Cauca, to evaluate their antibacterial activity and compare them with seeds of the same type grown in Ecuador. For this, the Liquid-liquid acid extraction of the seeds was carried out and the presence of flavonoids, steroids, saponins and alkaloids was determined by phytochemical screening. As the main result, lupanin was evidenced as the most abundant alkaloid, followed by sparteine and 3β-hydroxylupanine. In addition, it was found that the crude alkaloid extract of seeds grown in Valle del Cauca, presents more alkaloid content 95.8% compared to 50.0% of seeds grown in Ecuador.
