Elucidation of antimicrobial activity of Chinese chive against Helicobacter pylori

在本研究中，我们试图阐明冬葱对幽门螺杆菌的抗菌活性。结果表明，香葱提取物对51株幽门螺杆菌均有生长抑制作用。此外，它还具有杀菌活性。研究还表明，香葱提取物中的挥发性化合物对幽门螺杆菌有一定的抗菌作用。其中，主要活性成分为蛋氨酸衍生的S-甲硫代亚硫酸酯。

In this study, we tried to elucidate the antimicrobial activity of Chinese chive(Allium tuberosum) against Helicobacter pylori. As a result, the extract of Chinese chive showed the growth inhibitory effect against all of the 51 H. pylori strains. In addition, it had the bactericidal activity. It was also showed that the volatile compounds in the extract of Chinese chive contributed to the antimicrobial activity against H. pylori. In particular, S-methyl methanethiosulfinate derived from methiin was the main active component.
