Antifungal Activity and Qualitative Phytochemical Analysis of Green alga Ulothrix sp.

Abstract

The antifungal activity of the ethanolic hot extract of the green filamentous species Chlorophyta was evaluated in vitro at various doses (25, 50, and 100 mg/ml) and shown to be effective. Antifungal activity was performed by evaluating the percentage inhibition growth method against some fungus were obtained from the postgraduate laboratories in the Department of Biology - Faculty of Science / University of Mustansiriya (Aspergillus niger, Fusarium oxysporum, Penicillium sp. and Rhizoctonia solani ). As a result of the research, it was discovered that the hot ethanol extract of Ulothrix sp had the most significant effect (91.8 %) on Rhizoctonia solani growth inhibition at a concentration of 100 mg/ml and the minor effect (22.4 %) at a concentration of 25 mg/ml against Aspergillus niger growth inhibition. It was discovered by primary chemical analysis of active substances that alkaloids, Terpenes, Saponines, phenols, Flavones, Resins, Steroids, and tannins were present in hot ethanolic alga extract. Finally, the GC-mass analysis performed on Ulothrix sp extracts revealed a large number of antibacterial activity-producing substances. Because the current research shows that algae have antifungal activity, it has the potential to be developed as a new source of active chemicals for human and plant consumption in a variety of applications shortly.
