Abstract:  The antimicrobial action of Momordica charantia with a series of bacterium and fungi were studied. The results showed that the extract of Mchantia can effectively inhibit the growth of bacterium and some yeast, and that this extract is characterised by its heaf stable ability, low inhibting concentration and wide pH range on antimicrobe. The extract cannot effectively inhibit the growth of molds. The mechanism of antimicrobe needs further study.
