Obtención y rendimiento del extracto etanólico de dos plantas medicinales

Abstract: En el presente trabajo de investigación se evaluó el porcentaje de rendimiento de la extracción etanólica de las plantas medicinales Alegría (Scutellaria incarnata) y Amansatoros (Justicia pectoralis), al aplicar dos métodos de maceración con y sin agitación, con el material vegetal entero y molido, además de realizarse pruebas en diferentes tiempos de maceración (6, 12, 24, 48 y 92 horas) hasta llegar a la estabilización de la extracción. Para el análisis de los datos … Show more

“…In alcoholic extractions or with non-polar solvents, it is essential to eliminate these solvents and obtain only the dissolved compounds in them, leaving a liquid with a higher viscosity, dark in color, called crude extract [15]. This type of procedure is common in the industrial area, for the generation of commercial products, where one of the disadvantages is that certain molecules are susceptible to high temperatures, drastic temperature variations, the presence of sunlight and a lack of water in the environment [16,17]. Therefore, this is a disadvantage when used in healing processes in the presence of light, environments above 25°C and excess air currents, considering both animal skin, human beings and solutions and the pH value presented for each case.…”

“…The isotopic pattern of protonated or deprotonated molecules was consistent with that calculated by Thermo Xcalibur 3.1 software. The fragmentation pattern of [M+H] + and [M−H] − ions was studied using different energies (10,20,30,40,50,60, or 70 eV) in a higher-energy collision dissociation cell (HCD). The collision energy values were chosen while keeping in mind the highest number of product ions registered without losing the [M+H] + or [M−H] − signals of phenolic substances.…”

“…Scutellaria plants have long been employed in Asian and European regions [9]; their leaves, stems, and roots have been used to make infusions and ointments to control the symptoms of respiratory diseases such as the flu, asthma, and pneumonia, among others. In Colombia, the Paéz indigenous people (Cauca, southern Colombia) refer to Scutellaria by the name "Alegría" (happiness), because the infusion of leaves is also used to calm anxiety, depression the Paéz indigenous people (Cauca, southern Colombia) refer to Scutellaria by the name "Alegría" (happiness), because the infusion of leaves is also used to calm anxiety, depression and symptoms of respiratory diseases [10].

“…A partir de este material, se usaron dos métodos de extracción: infusión y extracción etanolica. Para la extracción por infusión se calentó 1 L de agua destilada a 80 ºC durante 10 min con agitación constante y se agregaron 500 g de cada planta (Benítez-Benítez et al 2019). Posteriormente, se filtró y se aforó a 1 L con agua destilada en botellas de vidrio oscuras estériles, para luego almacenar a baja temperatura (2 ºC) hasta su uso.…”
