Antifungal Activity Of Rosmarinus officinalis and Pelargonium Gravelens Essential Oils Extracts Against Aspergillus Flavus,Penicillium Brachycaulon. Andalternaria alternate

Abstract

The present paper aims todescribethe antifungalactivity of essential oils extracts with three concentrations which
are (25,33 and 50) mg\ml at significant differences (P ≤ 0.05)of Rosemary officinalis andPelargonium
gravelensessential oils extracts have been projected against some kinds of fungi (Aspergillus flavus;Penicillium
brachycaulonand Alternaria alternate) .TheRosmarinus officinalis essential oils extractshave been foundto
possess greater inhibitioninfluence of growth for both Alternaria alternateand Penicillium brachycaulonthat
reach (100)℅ in all concentrationsrespectively, followed by Aspergillus flavus at (50) mg\ml that amount
to(88.8)% ,while Pelargonium gravelensessential oils extractseffectinhibition of growth Penicillium
brachycaulonat (50) mg\ml that reaches to (100)%.As well as the same concentrations higher inhibition of
percentage to(79.7)% in growth of Aspergillus flavus.
Alsothese extracts that inhibition percentage influence the overlapping types of concentration extract of
growAlternaria alternateon SDA reached about(100)%,while the activity of extract against Penicillium
brachycaulon at concenteration(50) mg\ml opposing inconted toinhibitedamounted(100)℅.As recorded
inhibition ratio at the same concentered abovefor Aspergillus flavus which amounted to (82.4 )℅.
The highest inhibition ratio ofAlternaria sp.growth amounts to100% when it is mixedwith
Rosemaryofficinalisessential oils extracts in all concentration.The proportion ofAspergillusflavushas reached
(54.1)%, in Pelargonium gravelensextract on the same fungi.
