ABSTRACT
Chloroform, ethanolic, methanolic, ethyl acetate and aqueous root extracts of Anogeissus leiocarpus and Terminalia avicennioides were investigated in vitro for antifungal activities against Aspergillus niger, Aspergillus fumigatus, Penicillium species, Microsporum audouinii and Trichophyton rubrum using radial growth technique. The plant extracts inhibited the growth of all the test organisms. The minimum inhibitory concentration (MIC) of the extracts ranged between 0.03µg/ml and 0.07µg/ml while the minimum fungicidal concentration ranged between 0.04µg/ml and 0.08µg/ml. Anogeissus leiocarpus appears to be more effective as an antifungal agent than Terminalia avicennioides. Ethanolic extracts of the two plant roots were more effective than the methanolic, chloroform, or aqueous extracts against all the test fungi

Extracts of Cardiospermum gradiflorum and Cardiospermum halicacabumwere screened for antimicrobial activities against Candida albicans; Escherichia coli; Staphylococcus aureus; Bacillus subtilis and Streptococcus viridans using the agar diffusion method. The two plants produced antimicrobial activities against all the test organisms. C. grandiflorum exhibited higher antimicrobial activity than C. Halicacabum. S.aureus was the most resistant to the extract of C. Gradiflorum among the organisms assayed while E. coli was the most resistant to the leaf extract of C. halicaca. The mimumum inhibitory concentration of the extracts ranged between 35mg/ml and 50mg/ml. Cardiospermum Gradiflorum could be a more effective antimicrobial agent than Cardiospermum halicaca
