Description

technical field

[0001] The invention relates to an antibacterial composition, in particular to a natural antibacterial composition extracted from bellflowers, and also to an extraction method thereof. Background technique

[0002] Antibacterial drugs are the most widely used drugs in clinical practice, but there are many problems in the application of these drugs, such as drug resistance, toxic and side effects, bacterial flora caused by antibacterial drugs, superinfection, nosocomial infections, and allergies etc., especially the rapid rise of bacterial resistance. There is no effective drug available for the serious infection caused by this type of bacteria, which poses a great threat to human health. Therefore, at present, people develop new antibacterial drugs from natural resources as a focus of antibacterial drug research.

[0003] Bell grass is the whole grass or the whole grass with roots of the leguminous plant Crotalaria ferruginea Grah. Bellflower is a perennia...
