ABSTRACT
The antifungal properties of aqueous and ethanol extracts of Funtumia elastica and Mallotus oppositifolius were carried out using the disc diffusion agar assay. The crude extracts exhibited definite significant antifungal activity on most of the fungi. The zone of inhibition varied for the fungi, which were Aspergillus flavus, Candida albicans, Microsporium audouinii, Penicillium sp, Trichophyton mentagrophytes, Trichoderma sp and Trichosporon cutaneum with respect to the type of plant extract. The aqueous extracts of Mallotus oppositifolius had the highest zone of inhibition of 24.75 +/- 0.86 mm on Penicillium sp. The fulcin antibiotic had zone of inhibition of 11.94 +/- 0.43 mm on Microsporium audouinii, being its highest inhibition on any of the fungi tested. Preliminary phytochemical studies of F elastica and M oppositifolius extracts revealed that they contain anthocyanins, butacyanin, flavonoids, steroids and tannins. Phytobutanin was absent in the extracts. Heavy metal analysis of plant materials showed absence of cadmium, zinc, lead, chromium and nickel, while the presence of copper iron and manganese was less than 0.95.
RESUMEN
Las propiedades antifúngicas de los extractos acuosos y etanólicos de Funtumia elastica y Mallotus oppositifolius fueron probadas mediante ensayo de difusión con discos en agar. Los extractos crudos mostraron poseer una actividad antifúngica definitivamente significativa sobre la mayoría de los hongos. La zona de inhibición varió en correspondencia con los hongos, a saber, Aspergillus flavus, Candida albicans, Microsporium audouinii, Penicillium sp, Trichophyton mentagrophytes, Trichoderma sp y Trichosporon cutaneum, con respecto al tipo de extracto de planta. Los extractos acuosos de Mallotus oppositifolius presentaron la zona de inhibición más alta, a saber, 24.75 ± 0.86 mm, al aplicarse sobre Penicillium sp. El antibiótico fulcin presentó una zona de inhibición de 11.94 ± 0.43 mm al aplicarse sobre Microsporium audouinii, resultando ser ésta la inhibición más alta en relación con todos los hongos sometidos a prueba. Los estudios fitoquímicos de los extractos de F elastica y M oppositifolius revelaron contenidos de antocianinas, butacianinas, flavonoides, esteroides, y taninas. La fitobutanina estuvo ausente en todos los extractos. El análisis de metales pesados en las muestras de plantas mostró ausencia de cadmio, zinc, plomo, cromo y níquel, en tanto que la presencia de cobre, hierro y manganeso estuvo por debajo de 0.95%.
