Antimycotic activities of Cinnamon-derived compounds against Rhizoctonia solani in vitro
BioControl 54 (5), 697-707
Abstract: In this study, the effects of medicinal plant extracts on the development of mycelium in the following phytopathogenic fungi were evaluated: Phytophthora capsici, Rhizoctonia solani, Fusarium solani, Colletotrichum gloeosprorioides, and Botrytis cinera. Of the 26 medicinal plants tested, six plant extracts showed antifungal activity against phytopathogenic fungi. The highest antifungal activity was exerted against R. solani by the n-hexane fraction of a Cinnamon (Cinnamomum cassia Blume) solvent extract. Therefore, the antifungal compound fractions I and II were purified from the n-hexane fraction by TLC on silica gel plates. When treated with solutions containing compound fractions I or II at a concentration of 2%, the mycelia growth rate of R. solani was reduced to 0.19 and 0.18, respectively. In addition, microscopic observation of the hyphal morphology of R. solani following treatment with compound fraction I revealed the presence of severely damaged hyphae. Specifically, the hyphal tips became swollen, collapsed or were completely destroyed in response to treatment with solution containing compound fraction I at concentration of 1%.
