Fungitoxic Activity of Extracts from Azadirachta indica and Xylopia aethiopica on Colletotrichum lindemuthianum in Cowpea

Abstract: Hot water and oil extracts of Azadirachta indica (neem) and Xylopia aethiopica significantly reduced spore germination and growth of Colletotrichum lindemuthianum in vitro. Tests with cowpea (Vigna unguiculata) indicated the extracts applied before or after infection of the plants with Colletotrichum lindemuthianum were also effective in reducing the size of pathogen induced lesions. The fungitoxicity of the extracts from Azadirachta indica and Xylopia aethiopica was greater than that of bonomyl.

Fungitoxic effects of extracts from some West African plants

Abstract: Summary Extracts from five West African plants were evaluated in vitro for fungitoxicity against Ustilago maydis, Ustilaginoidea virens, Curvularia lunata and Rhizopus sp. Steam distillate from leaves of Cymbopogon citratus completely inhibited the growth of all four fungi, and hot water extracts from fresh leaves of Ocimum gratissimum and Chromoleana odorata, and dry fruits of Xylopia aethiopica, reduced radial growth by 10–60%. A hot water extract from dry fruits of Monodera myrstica was ineffective as a fungitoxicant.

Antimicrobial activity of essential oils of xylopia aethiopica

Abstract: Xylopia aethiopica is a medicinal plant of great repute in West Africa which produces a variety of complex chemical compounds. The fresh and dried fruits, leaf, stem bark and root bark essential oils showed various degrees of activity against the Gram positive bacteria, Bacillus subtilis and Staphylococcus aureus, the Gram negative bacteria Pseudomonas aeruginosa and the yeast-like fungus Candida albicans, using the cup plate method,. However, none of the oils showed activity against Escherichia coli.

Antimicrobial properties of some West African medicinal plants iv. Antimicrobial activity of xylopic acid and other constituente of the fruits of Xylopia aethiopica (Annonaceae).

Abstract: Xylopic acid and four other isolates from the fresh ripe fruits of Xylopia aethiopica a common ingredient in several Ghanaian folklore medicines and foods, have been examined for antimicrobial activity against five micro-organisms, Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa and Candida albicans. Xylopic acid and two other diterpene isolates were found to have antimicrobial properties.
