Ethyl Acetate Extracts

Objective: This study evaluated the Chaetomium cupreum extracts as biocontrol agents against four plant pathogenic fungi (Cladosporium cladosporioides, Fusarium oxysporum, Phomopsis azadirachtae, and Rhizoctonia solani).Method: The antifungal activity of n-butanol and ethyl acetate extracts of C. cupreum was evaluated against plant pathogenic fungi using food poison method.Result: In n-butanol extract, the percentage inhibition of mycelial growth against C. cladosporoides was 88.3±0.1, F. oxysporum was 59.4±0.2, R. solani was 56.2±0.9, and P. azadirachtae was 52.0±0.1at 0.25 mg/ml, respectively. In ethyl acetate extract, the percentage inhibition of mycelial growth against C. cladosporoides was 86.0±0.5, F. oxysporum was 66.4±0.1, P. azadirachtae was 55.2±0.9, and R. solani was 52.0±0.1 at 0.25 mg/ml, respectively.Conclusion: It was found that n-butanol extract is more effective than ethyl acetate extract of C. cupreum. Future studies will focus on the purification and characterization of compounds of C. cupreum and their biocontrol capacity with the mechanism for plant pathological applications.

Abstract Venturicidin X (la ), the aglycon of the venturicidins A (1b) and B (1c) was isolated for the first time as a natural product from an unidentified Streptomyces sp. Venturicidin X (1a) is highly active against a broad spectrum of plant pathogenic fungi.
