Abstract

Indonesia has a very large mangrove forest area, reaching nearly 3.5 million hectares or about 25% of the world’s total mangrove forests, with one of the dominant species being Rhizophora apiculata which grows in muddy tropical coastal areas. Plant extracts are a potential source of natural antimicrobial compounds because they contain various active substances with bacteriostatic properties that can be utilized as alternative therapies. This study aimed to identify the phytochemical metabolite compounds contained in mangrove leaf extract. The research design used in this study was a laboratory experimental design with a qualitative approach including the identification of flavonoids, tannins, saponins, and alkaloids. The results of the study showed that the phytochemical screening carried out on the mangrove leaf extract indicated the presence of several secondary metabolites, namely flavonoids, tannins, and saponins, which showed positive results in each test. These results conclude that mangrove leaf extract contains phytochemical metabolites including flavonoids, tannins, and saponins.
