Abstract

Phytochemical screening and Antifungal activities of Parthenium hysterophrous L (Asteraceae) was carried out in laboratory. Distilled water and methanol extracts of the leaves of plant was prepared. Five phytopathogenic fungi: Alternaria brassicae, Botrytis cinerea, Fusarium oxysporum, Phytophthora capsici and Sclerotium rolfsii were tested at different concentrations (50 mg/ml, 100 mg/ml, 150 mg/ml, 200 mg/ml, 250 mg/ml) of plant extracts. The phytochemical screening depicted the presence of terpenoids, saponins, flavonoids, tannins and alkaloids. The antifungal activity of extracts was determined by poisoned food technique; and linear mycelium growth reduction (LMGR) percentage was calculated. Methanol crude leaf extract had higher antifungal potential than the distilled water extract.

Conclusion

Leaves of Parthenium hysterophrous was rich source of important antifungal chemicals such as tannins, saponins, terpenoids, flavonoids, alkaloids, cardiac glycosides and steroids which has enabled them to show varying degree antifungal properties. Both distilled water and methanol crude leaf extracts exhibit antifungal action. However, methanol crude leaf extract had higher antifungal potential than the distilled water extract.
