The water extracts and 80% ethanol extracts from mulberry leaves of 108 kinds were tested their antimicrobial activities against Helicobacter pylori and antioxidant effects. The ABTS [2,2'-azino-bis(3-ethylbenzothiaznoline-6-sulfornic acid)] radical decolorization, electron donating ability (EDA), thiobarbituric acid reactive substance (TBARS) and antioxidant protection factor (PF) were determined for water extracts and 80% ethanol extracts from mulberry leaves. In the electron donating activity, the 13 kinds of water extracts showed high inhibition (>80%), whereas the 59 kinds of 80% ethanol extracts showed high inhibition. The inhibitory activities of water extracts from all kinds of mulberry leaves were higher than 90% in ABTS [2,2'-azinobis(3-ethylbenzothiaznoline-6-sulfornic acid)] radical decolorization. The thiobarbituric acid reactive substance (TBARS) and antioxidant protection factor (PF) of the 80% ethanol extracts were higher than that of water extracts. Antimicrobial activity against Helicobacter pylori showed high value in 80% ethanol extracts of 15 kinds mulberry leaves. The results implied that the mulberry leaves can be useful for natural antimicrobial medicine.
