Secondary metabolites are compounds produced by plants, microorganisms and animals through the process of biosynthesis or derivatives from primary metabolites. The maceration method is a simple way to separate bioactive compounds from plant material. Guava leaves contain secondary metabolite compounds which have medicinal effects such as antibacterial, antioxidant and anti-inflammatory. This simplicia leaf is soaked in 96% ethanol (using the maceration method) for 24 hours and concentrated using a rotary evaporator. Alkaloid, flavonoid and saponin tests show that guava leaves contain these three compounds. These compounds have potential for development in the pharmaceutical field.
