[PDF] Antifungal activity of medicinal plant extracts against phytopathogenic fungus Alternaria spp. | Semantic Scholar (2024)

The results of this study indicate that foliole extracts of M. oleifera have potential for use as biofungicides for plant protection against fungal diseases.

It could be concluded that, the ethanolic extracts of Calligonum comosum exhibit powerful fungicidal properties indicating the presence of potential antifungal compounds effective in the treatment of plant diseases.

It was observed that ethyl acetate extract of rhizomes of C. aromatica and unripe fruit rinds of G. indica have shown the lowest MFC values amongst the other tested plant extracts.

Results showed that methanol extract of C. senna and ethanol extract of P. nigrum displayed excellent inhibition on dermatophytes compared with standard antifungal drug, and the chemical compositions of these extracts were analyzed by FLC (Fast Liquid Chromatography).

The extracts of Pulicaria crispa and Olea chrysophylla were the most effective antifungal followed by Citrullus colocynthis, Psiadia arabica and Otostegia fruticosa, which contain biologically active major compounds such as alkaloids, flavonoids, saponins, tannins and terpenoids.

The results show that the five commercial extracts have potential for the development of natural antifungal agents, which could be an alternative to chemicals for control of phytopathogenic fungi on fruits or vegetables.

The conclusion from this study is that M. hirtus plant extract has antifungal activity against E. floccosum, Trichophyton sp, and Microsporum sp almost similar with commercial fungicidal drugs (Terbinafine).

The most frequently occurring constituents in essential oils showing high antifungal activity were: D-limonene, cineole; β-myrcene; α-pinsene, β-pinene; and camphor.

High susceptibility of A. flavus recorded high susceptibility and hence solvent extracts viz., petroleum ether, benzene, chloroform, methanol and ethanol extracts of all the twelve plants were tested for their antifungal activity against it, except for Polyalthia longifolia, where petroleum ether extract recorded highly significant antifunkal activity than other solvent extracts.

The extracts from the studied plants may be promising in the control of early blight on tomato plants, after being incorporated into potato-dextrose-agar medium and having significant effects on the reduction of germination and sporulation.

It is hypothesized that sampangine, except against C. acutatum, has the same physical mode of action, germination inhibition, as the conventional fungicides captan, iprodione, and kresoxim-methyl.

The oil of Schinus molle exhibited the maximum fungitoxic activity during the screening of some essential oils against some common storage and animal pathogenic fungi and was found to be more effective than Multifungin, an antifungal drug.

This review focuses on the significance of fungal resistance to plant antibiotics as a mechanism of pathogenesis, and the emphasis to date has been on degradative mechanisms of resistance of phytopathogenic fungi to antifungal secondary metabolites.

An antifungal peptide was isolated from Amaranthus hypochondriacus seeds by acidic extraction and then purified by reverse-phase high-pressure liquid chromatography, and it was found that Ay-AMP degrades chitin.
