Nutrients produce various secondary metabolites, including biologically active compounds such as antifungals. The composition of E. Crassipes aquatic plant contains biologically active substances. In this article, the composition of substances in E. Crassipes was identified using IR, 1H, and 13C-NMR methods. The identified substances were characterized for biological activity using the PASS online program. This was based on their molecular structure. As a result of the program, compounds showing activity against light, viruses, earwigs, and bacteria were developed. The program’s scope included testing the substances’ antimicrobial activity using agar diffusion assay in experiments. Substances were extracted from the aquatic plant via chromatography-mass spectrometry, and their activity against earwigs was examined. The study revealed efficacy against Candida albicans and Candida utilis earwigs.
