Study on the antioxidant and antitumoral activity of propolis

Introducción: El propóleo es la sustancia que protege a la colmena, es una resina de composición compleja y viscosa que las abejas utilizan en la reparación y protección de la colmena. El material del que procede el propóleo son las resinas, brotes y pecíolos de las hojas de diferentes vegetales, por ello presenta una composición química muy compleja que varía en función de la flora de recolección de las abejas. Posee capacidad antimicrobiana, antiinflamatoria que está relacionada con su poder antioxidante, inmunomoduladora, entre otras. Objetivos: En este trabajo se estudian las actividades antioxidantes y antitumorales de propóleos de distintas zonas de la provincia de Málaga comparándolos con uno de la región de Bohemia al sur de la República Checa. Material y métodos: La actividad antioxidante se evaluó según el método ABTS+/S2 O8 K2 . Además se estimó la cantidad de proteínas totales a partir del contenido de nitrógeno y posteriormente se determinó la citotoxicidad y actividad antitumoral del propóleo del Puerto de la Torre, al norte de Málaga, según el método del bromuro de 3-(4,5-dimetiltiazol-2-il)-2,5-difenil tetrazolio. Resultados: Se observó que el propóleo presenta una elevada actividad antioxidante, aunque tiene una menor cantidad de proteínas. El propóleo presenta elevada toxicidad y mayor actividad antitumoral frente al cáncer de colon que al de leucemia. Conclusión: Con todos estos datos obtenidos se puede concluir que el propóleo presenta diferentes actividades de interés para la industria alimentaria o cosmética, entre las que destaca su elevado poder antioxidante y su capacidad como antitumoral.Introduction: Propolis is the substance that protects the hive, a resin of complex and viscous composition bees use in the repair and protection of the hive. The material from which propolis arises are the resins, shoots and petioles of the leaves of different plants, so it has a very complex chemical composition that varies depending on the flora of the bees collection. It offers an antimicrobial, anti-inflammatory capacity related to its antioxidant, immunomodulatory power, among others. Aims: In this work, antioxidant and antitumoral activities of different propolis collected from different areas of the province of Malaga, comparing them with one from the Bohemian region to the south of the Czech Republic are studied. Material and methods: Antioxidant activity was determined according to the ABTS+/S2 O8 K2 method. In addition, the quantity of total proteins from the nitrogen content and subsequently the cytotoxicity and antitumoral activity of the propolis of Puerto de la Torre, north of Malaga, are measured according to the 3-(4,5-dimetiltiazol-2-il)-2,5-diphenyl tetrazolium bromide method. Results: It was observed that propolis has high antioxidant activity, although it has a lower amount of proteins. Propolis has high toxicity and higher antitumoral activity against colon cancer than leukemia. Discussion: With all these data, it can be concluded that propolis offers different activities of interest, for the food and cosmetic industry, among which the high antioxidant and antitumoral capacity
