The aim of this
investigation was to evaluate the antifungal activity of extracts of 11
different medicinal plants species from Trans-Himalayan region against the
phytopathogenic fungus Aspergillus niger and Aspergillus flavus. Methanolic
extract of Codonopsis clematidea, Hippophae rhamnoides, Artimesia dracunculus,
Galium aparine, Mentha longifolia, Foeniculum vulgare, Rubia coradifolia,
Saussurea lappa, Inula racemosa, Rheum webbianum and Arnebia euchromawere
screened for its antifungal activity. The plants were selected on the basis of
their reported ethnobotanical uses and locally available. Results revealed that
all the concentrations of plant extracts brought about significant inhibition
in the growth of these pathogenic fungi Aspergillus niger and Aspergillus
flavus. All the three concentrations of the 12 tested plant extracts were found
to be significantly inhibitory to fungal growth and the rate of inhibition
increased generally by increasing the concentration. Similarly antifungal
activity of plant extracts showed significant activity when compared with the
leaf/root extract against the two Aspergillus spp. The results indicated that
all tested plant extracts had different degrees of antifungal activity against
the tested pathogenic fungi. Hence, the objective of this study was to
determine if plant extracts could provide antifungal activity against some
plant pathogenic fungi. The results obtained from the present investigation
clear that the antifungal activity vary with the species of the plants, plant
material and the concentration used. - See more at: .
