RESUMO

Aims@#Andrographis paniculata (AP), a medicinal herb was selected to investigate the antifungal activity on selected dermatophyte fungi. The phytochemical screening was also carried out to evaluate its chemical constituents.@*Methodology and results@#The potato dextrose agar (PDA) incorporated with aqueous, ethanol and methanol AP extracts at concentrations 0.99% (v/v), 1.96% (v/v) and 7.41% (v/v) were used for selected fungi culturing; Trichophyton mentagrophytes, T. rubrum, T. interdigitale, Microsporum fulvum, M. nanum, M. gypseum, M. canis, Fusarium solani and Aspergillus fumigatus. Phytochemical screening showed the presence of flavonoids, saponins and tannins in the ethanol extract and flavonoids alone in both aqueous and methanol extracts. Studies on antifungal effects indicated that the ethanol extract significantly increased the mycelial inhibition percentage of all tested fungi, especially at a concentration of 7.41% (v/v). All ethanol AP extract concentrations inhibited M. gypseum and M. canis (p<0.05) with at least 36.00% mycelial inhibition. In aqueous AP extract, it significantly increased the mycelial inhibition of T. mentagrophytes, T. interdigitale and M. gypseum (p<0.05), while the methanol AP extract significantly inhibited all fungi at a concentration of 7.41% (v/v) except for T. rubrum, M. gypseum and F. solani (p<0.05). No spore sedimentation was recorded for the fungal spores of T. rubrum, M. nanum, T. mentagrophytes, M. gypseum and T. interdigitale at 7.41% (v/v) ethanol AP. @*Conclusion, significance and impact of study@#It is concluded that the ethanol AP extract contained phytochemical constituents and showed the highest antifungal activity. In addition, this extract has a great potential to treat dermatophytes effectively.
