Six extracts from Chinese medicinal plants: Tin Men Chu, Sey Lau Pai, Siu Mao Heung, Bak Tao Yung, Kam Chin Chiu and Liao Ya, were tested for their inhibitory effect on selected food-borne bacteria by the well assay technique. Among them, Tin Men Chu, Siu Mao Heung and Sey Lau Pai inhibited the growth of Staphylococcus aureus, Klebsiella pneumonia, Escherichia coli, Shigella flexneri, Streptococcus faecalis, Salmonella paratyphi, Salm. enteritidis, Enterobacter aerogenes, Pseudomonas fluorescens, Proteus vulgaris, Alcaligenes faecalis, and three strains of Listeria monocytogenes. Two of these three extracts, Tin Men Chu and Siu Mao Heung, suppressed the growth of L. monocytogenes Scott A in cabbage juice. This inhibition was prevented by the addition of protein but not sodium chloride. Plant extracts show potential to control the growth of food-borne bacteria.
田边菊、溪黄草、白毛根、白术、金钱草和蓼芽，采用打孔法检测它们对特定食源细菌的抑制作用。其中，田边菊、白毛根和溪黄草抑制金黄色葡萄球菌、肺炎克雷伯菌、大肠杆菌、福氏志贺菌、粪肠球菌、副伤寒沙门氏菌、肠炎沙门氏菌、产气肠杆菌、荧光假单胞菌、普通变形杆菌、粪产碱菌以及三株单核细胞增生李斯特菌的生长。这三种提取物中的两种，田边菊和白毛根，抑制了单核细胞增生李斯特菌Scott A在白菜汁中的生长。添加蛋白质可阻止这种抑制作用，但添加氯化钠则不能。植物提取物显示出控制食源细菌生长的潜力。
