Abstract:
The phytochemical screening, and in vitro antifungal activity of the inflorescence, leaf, stem and rhizome crude extracts of Costus lucanusianus J. Braun & K. Schum at concentrations 12.5-100 µg/mL were determined against 4 fungal strains; Penicillium notatum, Candida albicans, Aspergillus niger and Rhizopus stolonifer by Agar well diffusion method. Secondary metabolites accountable for the activity observed are saponin, tannin, flavonoid, phlobatannins, reducing sugar, anthraquinones, phenol, alkaloid, resin, glycoside and terpenoids. Reducing sugar was present in all the extracts. The rhizome solvent extracts displayed the highest antifungal activity amongst the organs extracts. The inflorescence, stem and rhizome aqueous extracts displayed no activity at all concentrations.
In this present study, the antifungal activity of Costus lucanusianus J. Braun & K.Schum aerial and rhizome extracts is reported. The activity shown by the plant organs justifies the use of the plant in the treatment of urinary tract infection and venereal diseases in ethnomedicine, and its usefulness in the preservation of food crops.
