| Abstract: | Extracts from 6 species of IPomoea batatas Lam leaves have been determined for their bacteriostatic effects on five types of pathogenetic bacteria (Escherichia coli,Bacillus subtilis, staphylococcus aureus, staphylococcus albus, and Proteus vulgaris) by using the methods of the filter paper disk tests and the dual-flat tests. It has been found that 4 among them (SPGS-1, SPGS-2, SPGS-3 and SPRS) have obvious bacteriostatic effects on the pathogenetic bacteria, with their lowest inhibition concentration ranging from 0. 4g/ml to 1. 0g/ml. |
