التأثير التثبيطي لأوراق الحناء Lawsonia inermis على بعض الفطريات

الملخص EN

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
