Natural products are used in wound healing in order to prevent infection. Propolis is a well known antimicro-bial with phenolic compounds and flavonoid content which vary according to the propolis origin. Besides propolis (from both Brazilian and UK sources), pomegranate, dragon’s blood and sage are possible antimi-crobials to be used in biomaterials. The goal of this work was to analyze the amount of phenols and flavonoid compounds in these natural products, their antioxidant activities and the bonds present by FTIR. The FTIR analysis revealed the presence of active compounds in all drug samples. The phenols quantification showed that Brazilian propolis was rich in phenols compared to the other drugs, followed by pomegranate and UK propolis. UK propolis was the most rich in flavonoids, which is expected on account of its origin. Pomegran-ate, UK propolis and Dragon’s blood presented the highest antioxidant activity. All samples presented antiox-idant activity > 82%.
