摘要
Hylomecon japonica (Thunb.) Prantl. is a Chinese medicinal plant whose active components and their antimicrobial mechanism was studied by TLC bioautography-guided isolation and identification of 12 alkaloids and their antimicrobial activities evaluated using the standard broth microdilution method. The benzophenanthridine isoquinoline alkaloids showed the strongest inhibitory activity against Gram-positive bacteria. Analysis of conductivity changes and observation of TEM images revealed that the antimicrobial mechanism involved cell integrity damage and cell division arrest.
