Study on the antibacterial effect of 16 kinds of Lingnan genuine medicinal materials on Streptococcus pneumoniae
To study the in vitro antibacterial activity of 16 unique Lingnan medicinal herbs against Streptococcus pneumoniae.Using Streptococcus pneumoniae as the test strain,the minimum inhibitory concentration(MIC)and minimum bactericidal con-centration(MBC)of 16 authentic Lingnan medicinal herbs were determined using a 24 well plate culture method.The results showed that among the 16 Lingnan characteristic medicinal herbs,11 have antibacterial activity against Streptococcus pneu-moniae,including Persicaria chinensis(L.)H.Gross,Cinnamomum cassia Presl,Viola inconspicua Blume,Radix Ilicis Asprel-lae,Pogostemon cablin,Vernonia amygdalina Delile,Microcos paniculata,Emilia sonchifolia,Dicliptera chinensis,Evodia lepta and Elephantopus scaber.Among them,the ethanol extracts of Viola inconspicua,Pogostemon cablin,Vernonia amygdalina Delile,Dicliptera chinensis,Evodia lepta,and Elephantopus scaber showed strong antibacterial activity.The ethanol extracts of some unique Lingnan medicinal herbs have good antibacterial effects on Streptococcus pneumoniae.
