Bioactivity of Some Plant Extracts On Some fungi Isolated Clinically

This study aimed to evaluated the efficiency of aqueous and alcoholic extracts for eleven of medicinal plants: leaves  Rosemarinus officinalis ; flowers Borago officinalis  ;seeds Theobroma cacao ; seeds Brassica nigra ; leaves Artemisia vulgaris; seeds Cyndonia oblonga ; fruits Terminalia chebula ; fruits  Quercus infectoria; fruits Rhus coriaia ; flowers Eugenia carophyllus; fruits Citrus aurantium  against eight fungal species: Trichophyton mentagrophytes; Epidermophyton floccosum; Aspergillus  flavus ;Aspergillus candidus  ;Aspergillus oryzae Aspergillus terreus  ; Aspergillus tamarii ;Aspergillus parasiticus.using distilled water to prepare the aqueous extracts and ethanol 95% was prepared of alcoholic  extracts.

The antifungal activity of plant extracts with different concentration 3,5,7,10,15,20 mgml were tested to evaluate  the activity of these extracts against the fungal  isolates , an inhibitory percentage was determinate then the minimal inhibitory concentration was estimated for each plant extracts  against the fungi.

By the statistical anylysis many results were appeared, the most important of  them were that: alcoholic was founded to be the best among the plant extracts, The fungal isolates E.floccosum was the more sensitive than other fungal species to the plant extracts and alcoholic extract of  flowers Eugenia carophyllus  was the best inhibition the growth of studied fungi.

According to the previous results, the study attempted to some of active constituents of plants by using many chemical reagents.The phytochemical  tests  revealed  that  all plants  containd  spaonins except fruits Rhus coriaia; seeds Theobroma cacao and seeds Cyndonia oblonga,  flowers Eugenia carophyllus contained Tannis, and Resins,  While fruits Citrus aurantium, fruits Quercus infectoria and seeds Theobroma cacao contained Glycosides , While fruits Rhus coriaria contained Resins,Tannins, fruits   Terminalia chebula and seeds Cyndonia oblonga were contained Resines ,Tannins,While leaves Artemisia vulgaris contained Alkaloids and Flavonids, flowers Borago officinalis contained Glycosides , While seeds Brassica nigra contained Tannins and Resines , The leaves Rosemarinus officinalis contained Flavonids,Tannins,  Glycosides and Alkaloids .
