The inhibitory effect of henna Lawsonia inermis leaves on some fungi
Abstract
4 Aspergillus A. candidus A. flavus A. niger A. tamarii Fusarium culmorum Penicillium spp. Pythium spp. Trichophyton mentagrophytes . 20 / A. tamarii A. flavus (56 49) % Pythium spp. T. mentagrophytes Penicillium spp. . F. culmorum Pythium spp. 100% 20 / 100% A. candidus A. tamarii spp. Penicillium T. mentagrophytes 89% A. flavus A. niger 67 % 5 10 / .The present study investigates the effect of water & alcoholic extracts of henna Lawsonia inermis leaves on four fungal species of Aspergillus including A. candidus, A. flavus, A. niger & A. tamarii, also it involves one fungal isolate of each of Fusarium culmorum, Penicillium spp., Pythium spp. & Trichophyton mentagrophytes. The results prove that there is inhibitory effect against fungal growth in general, & the inhibition percents are weak when water extract of leaves is used.The concentrate 20 mg/ml is the best to be used for inhibition. The highest percents of inhibition prove to be achieved against fungal species of A. tamarii & A. flavus. These percents are (56 & 49) % respectively, while percents of inhibition are weaker concerning the rest of fungi & with all concentrates.The fungi of Pythium spp., T. mentagrophytes & Penicillium spp. show no response to any concentrate of water extract.The findings show that alcoholic extract has priority to that of water in its ability of inhibition with all concentrates, & the fungi of F. culmorum & Pythium spp. prove to be more affected by alcoholic extract, they prove to achieve 100 % inhibition for all concentrates.Also, we can clearly notice that 20 mg/ml concentrate of alcoholic extract is the best for inhibition against all fungi. It proves to achieve 100 % inhibition against another four fungi which are A. candidus, A. tamarii, Penicillium spp. & T. mentagrophytes . Also, it shows an ability to reach 89 % inhibition against fungus of A. flavus . The fungus of A. niger shows to be less effected by this concentrate. It gives 67% of inhibition & it shows no response to 5 & 10 mg/ml concentrate of alcoholic extract.
