“…The presence of vitamin C in the extracts may confirm the reported wound healing property of the plant (28). The presence of vitamin C in Spondias mombin leaves and stem bark, implies that it can be used in herbal medicine for the treatment of common cold and other diseases like prostate cancer (17,29).…”

“…The stem back and leave extracts also contained the antioxidant vitamins C and E. Antioxidants repair free radical damages to the cells (29). The presence of antioxidant molecules suggests that Spondias mombin can be used as vitamin supplement probably during oxidative stressed conditions.…”

Abstract:The cholinesterase and microbial inhibitory activities of different parts of Tetrapleura tetraptera plant were evaluated due to their local applications. The cholinesterase results revealed that the extracts showed some levels of inhibitory effects depending on the solvents used. Tetrapleura tetraptera leaves had better inhibitory effects with maximum inhibitory activity of 70.0% at a concentration of 1.00mg/l for the water extract. Tetrapleura tetraptera bark showed highest inhibitory effect of 71.05% and (84.34%) for the ethanol and chloroform extracts at concentrations of 0.5mg/l and 1.0 mg/l respectively. While for petroleum ether, T. tetraptera bark recorded 74.34% inhibitory effect at concentration of 2.0 mg/l and also showed continuous increase in inhibitory activity as the concentration increases for aqueous methanol. The results of the antimicrobial activities showed that among all the test organisms, the ethanol and water extracts of the leaves, stem, bark and root of the plants had promising activity against Escherichia coli, Staphylococcus aureus, Proteus mirabilis, Pseudomonas aeruginosa and Klebsiella pneumonia bacteria and Aspergillus fumigatus and Rhizopus species fungi. There was no activity shown by the ethanol and water extracts of the parts of the plants with Fugarium oxysporum, Penicillium chrysogenum and Mucor species fungi. The bacteria strains were more sensitive to the tested extracts than the fungi strains.

“…Biological investigations carried out on several species from the genus Aframomum, of the family Zingiberaceae revealed their antiparasitic, antifungal, antibacterial and antiviral properties. (Cousins and Hoffman, 2002;Okwu et al, 2003). Further studies showed their analgesic, aphrodisiac, antiinflammatory, antioxidant, antiulcer and antiprotozoal efficacies (Singh et al, 2007;Cheikh et al, 2011) while the seeds of Aframomum species have been found to contain phytochemicals (Fasoyiro and Adegoke, 2007).…”

ABSTRACT:In different parts of the world, attention is being paid to exploitation of higher plants as biodegradable fungicides in the control of most plant pathogenic fungi. Different spices of the Zingiberaceae family have been tested for their antifungal properties, but there exists little or no information on the antifungal potential of a particular member of that family; Aframomum sceptrum on fungal pathogens of some economic important palms in Nigeria. In this study, the phytochemical composition of the seed extracts of this spice was analyzed by standard methods while the antifungal activities of polar and non polar extracts of the spice was tested on two major isolates affecting the Oil palm, Fusarium oxysporum f.sp elaeidis and Hypocrea lixii (IMI 501885) Cold extraction using Acetone, Ethanol, Hexane, Methanol, and Diethylether solvents were used in the seed extract preparation. The broad spectrum fungicide, Mancozeb (80% wettable powder) was used as the positive control while the negative control was Dimethyl sulphoxide. The Dimethyl sulphoxide was also used to reconstitute the solvent extracts by dissolving the extracts and fungicides in appropriate amount of 15 % (v/v) to obtain a concentration of 0.0624g/ml. The phytochemical screening revealed the presence of the following phytochemicals in different quantities; Alkaloids, Terpenoids, Anthraquinones, Flavonoids Tanins, Saponins. Results obtained showed that all the extracts had a significantly higher antifungal effect (p< 0.05) than the broad spectrum fungicide, Mancozeb at 2000ppm. Non polar hexane seed extract had the highest percentage inhibition of 60.26% on Hypocrea lixii (IMI 501885 while the Polar ethanolic extracts with a percentage inhibition of 52.73 % on Fusarium f.sp elaeidis. Amongst all the extracts used in this study, the seed extracts that gave a low percentage inhibition of 42.45% was the non -polar acetone seed extract on Fusarium oxysporum fsp. elaeidis and methanol extract on H .lixii with the least percentage inhibition of 42.31%. The implications of these findings are discussed. © JASEM http://dx.doi.org/10.4314/jasem.v18 i2.4
