Item Obtención y evaluación de la actividad antibacteriana del extracto de las semillas de guanábana (Annona Muricata L.)(Universidad Santiago de Cali, 2024) Cortes Chalar, Sharon Juliet; Chacon Londoño, MerlyTatiana; Quijano Pérez, Silvia Andrea; Morales, Jimmy AlexanderGuanabana (Annona muricata L.) is a plant native to South America, is widely distributed in the tropical and subtropical regions of the world; it is characterized by the high potential that has its properties and the variety of biological activities that these possess, such as: insecticides, antibacterials, anti-corrosive, among others; which are of great interest in the pharmaceutical and food industries. Traditionally, non-eatable seeds are a high-availability residue whose composition has been the subject of extensive research. In many of the fruit pulp production industries, seeds are converted into waste without any apparent value, but this waste can now be recovered in an integrated way during the industrial application of subsequent processes, transforming the waste into secondary raw materials and allowing the extraction of value-added compounds through sustainable and green methodologies. The aim of this research work was to evaluate the antibacterial activity of the extract of the seeds of guanabana (Annona muricata L.) against pathogenic microorganisms such as: Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853 by the Soxhlet extraction method, using two solvents (etanol y cloroformo). As a result, an aquatic extract of the guanabana seed was obtained with a yield of 16.5 to 33.6%. However, the result of the qualitative evaluation of the antibacterial activity of this extract was not what was expected, in comparison with the literature due to different aspects to be considered such as: the level of concentration, the raw material used, the moisture in the seeds, the solvents employed, the extraction method used, bacterial species, among others. In conclusion, guanabana seed extracts can be an alternative for the development of products with potential antibacterial applications, such as pre-treatment for biological control of fruit diseases after harvest, from a pharmaceutical and food point of view. Additional studies may also be carried out to determine the larvicidal and insecticidal capacity it may possess
