Abstract

The purpose of this research was to investigate antifungal activity of Eusiderin A from Eusideroxylon zwagery against Rhizoctonia solani and Gliocladium fimbriatum. Antifungal activity of Eusiderin A (3, 4, 5 ppm) was studied against pathogenic plant fungus using PDA (Potato Dextrose Agar) as testing culture media at room temperature, and were monitored for 5 days. The invitro antifungal activity was performed by agar well diffusion method. Eusiderin A, a rare benzodioxane-type neolignan was isolated as major component from E. zwagery which showed potent antifungal activity against Rhizoctonia solani and Gliocladium fimbriatum. Eusiderin A was at a concentration of 5 ppm to give most effective inhibition, 21.95% on the colony growth of Rhizoctonia solani. Whilst it had no inhibitory activity against the growth of Gliocladium fimbriatum colony. The result was in line with Gliocladium fimbriatum’s nature as antagonist agent against various pathogenic plants and it is very well known as a biological control. It can be concluded that Eusiderin A was a candidate compound for a potent antifungal agent since it could exhibit Rhizoctonia solani colony growth. Keywords: Eusiderin A, Eusideroxylon zwagery, Rhizoctonia solani, Gliocladium fimbriatum
