ABSTRACT

Phytochemical screening involves the systematic extraction and identification of bioactive compounds in plant and other species; aims to determine their chemical constituents and potential medicinal properties. Phytochemical analysis was conducted through the aid of a standard test. This study aimed to analyse the secondary metabolites of Rhizophora mucronata and evaluate their bioactivity through Probit Analysis and determination of LC50 values. The phytochemicals detected in the methanol extracts of R. mucronata revealed a diverse profile of secondary metabolites, including the presence of alkaloids, flavonoids, phenols, tannins, saponins, triterpenoids, steroids and cardiac glycosides. Probit Analysis was used in this study to determine the lethal concentration of R. mucronata extracts against brine shrimp (Artemia salina). It yielded to a non-toxic result: LC50 value 1905.46 μg/ml. The findings of this study contribute to a better understanding of the chemical composition and biological activities of this species. Further, the identified secondary metabolites and their associated bioactivities hold potential for the development of natural products with applications in medicine and environmental remediation.
