Abstract

This experimental study focused on the inhibitory effect of makahiya, coconut and guava leaves extract on Aspergillus niger, Fomes lividus and Lenzites striata. Each leaf extracts was replicated and placed in three different concentrations. A control medium was used to determine the effectiveness of each leaf extract as an antimicrobial agent. The test organism was acquired by the researchers from the laboratory of University of the Philippines Los Baños, from the prepared test tubes of the said organisms. Further isolation and replication of the test organism was also done by the researchers. The data gathered were analyzed using the mean and percentage. Results revealed that makahiya and guava leaves extracted from acetone exhibited an effective inhibitory effect on the growth of Aspergillus niger. Based on the findings, the researchers concluded that the water, alcohol and acetone when used as solvents for the guava, coconut, and makahiya leaves extracts varied with the solvents and test organisms employed.
