The results showed that the patchouli aqueous extract and volatile oil had certain inhibitory effect on Salmonella, Escherichia coli, Shigella, Staphylococcus aureus and other common intestinal pathogens, the inhibition of Staphylococcus aureus was significantly stronger Enterobacteriaceae (P <0.01). In addition, the antimicrobial effect of high-concentration patchouli water extract on intestinal pathogens was significantly stronger than that of Wuchuan patchouli (P <0.01).
