Antifungal Activity of Geodorum densiflorum (Lam.) Schltr. against Pathogenic Fungi

Introduction: Nowadays scientific researches on the medicinal plants are increased because of their extraordinary applications in both human and plant disease control. Therapeutic alternatives from plants were having empirically high antifungal properties against wide range of fungi.
Aim: Present study deals with the antifungal activity of Geodorum densiflorum (Lam.) Schltr. an medicinal orchid against various infective fungus.
Material and Methods: Plant extract using different solvents such as water, ethanol and chloroform was evaluated against Penicillium chrysogenum (MTCC 6449), Aspergillus niger (MTCC 4325), Rhizoctonia solani (MTCC 4634) and Colletotrichum falcatum at different concentrations (25, 50, 75 and 100 mg/ml). Result: Maximum antifungal activity was observed with ethanol extract of the orchid, which recorded excellent inhibitory activity against all four pathogenic fungi when compared with the fluconazole as standard. Conclusion: It is hoped that Geodorum densiflorum will compromise the search for potent antifungal agent by young researchers.
