Effect of Ethanolic extracts of four plant species in the inhibition of growth of three Aspergillus sp. spesies in Vitro

Abstract

The research included a test of the efficiency of  ethanolic  extracts of  Gardenia  jasminoides, Citrus sinensis and Chrysanthemum coronarium flowers and Rhus coriaria fruits in inhibiting the radial growth of three spesies of Aspergillus, A.niger, A. flavus and A. terreus,  in three  concentrations 5%, 10% and 15%  on PDA in vitro.

The results showed that all of  the tested extracts in  all concentrations inhibited in vary proportions growth of the tested fungies, there were  significant differences between  the different concentrations of each extract and the inhibitaion  increased as the concentration  increased.

The results also  showed that R. coriaria fruits extract and C. sinensis flowers extract were the most effective inhibiting growth of tested fungies , the inhibitaion at concentration 15% ranged from  91.47% to 100%  and G.  jasminoides  flowers extract ranged from 86.20% to 100% and finally Ch. coronarium flowers extract was (78.66% to 100%) against three tested pathogens.
