Antibacterial Effects on Oral Microorganism and Inhibitory Effects of Halitosis of Omija ( Schizandra chinensis baillon ) extract

We examined antibacterial effects on representative oral microorganism, namely Streptococcus mutans, Escherichia coli and Candida albicans, and inhibitory effects of halitosis of Omija ( Schizandra chinensis baillon ), a natural medicinal herb. In case of S. mutans as a typical pathogenic microorganism causing for dental caries and E. coli as accounting for 15 percent of all oral flora, extracts of omija showed antibacterial effects of in 2.5 ㎎/㎖ over than penicillin (100 unit). Antibacterial effects of extracts of omija grew larger according to the increase in density. In case of C. albicans as a typical fungi and opportunists of normal oral flora, extracts of omija also showed antibacterial effects in 2.5 ㎎/㎖ over than penicillin (100 unit) but had little antibacterial effects than S. mutans and E. coli and there are no changes of antibacterial effects according to the density of extracts. Extracts of omija also showed inhibitory effects of halitosis in 2.5 ㎎/㎖ over and the largest inhibitory effect in 5.0 ㎎/㎖. This is show that there is not only a fair chance for the utilization of extracts of omija as an effective antibiotic to bacteria and fungi but also as a depressor of halitosis.
