The ethyl acetate extract, aqueous extract and membrane separation extract from the tubers of Smilax china were investigated for anti-bacterial and anti-fungal activity by agar plate disc-diffusion assay. All the three extracts showed anti-bacterial effects against all Gram-positive bacteria, Gram-negative bacteria and fungi tested. Among anti-bacterial activities of these extract, the ethyl acetate extracts exhibited stronger anti-microbial activity against Gram-positive bacteria as compared to aqueous extract and membrane separation extract showed similar to and even stronger anti-microbial ...
