Abstract

The invention relates to an anti-MRSA nettle extract and an extraction method thereof. The anti-MRSA nettle extract is separated and extracted from nettle by using an alcohol solvent. The alcohol solvent is methanol or alcohol, or a combination of the methanol and the alcohol. Applications of the anti-MRSA nettle extract and the extraction method of the anti-MRSA nettle extract in preparation anti-MRSA drugs are also disclosed.

Description

technical field [0001] The invention relates to the technical field of anti-MRSA, in particular to an anti-MRSA nettle extract and its extraction method and application. Background technique [0002] Staphylococcus aureus (Staphylococcus aureus, SA) is an important human pathogen, which was recognized as the cause of pyogenic abscess more than 130 years ago. It belongs to the genus Staphylococcus and is a representative of Gram-positive bacteria. Staphylococcus aureus can invade the body through various channels, leading to various infections of the skin or organs, even sepsis, etc., and can also cause dysfunction of multiple organ systems in the body or cause toxic shock syndrome. The infection can range from mild to severe. Skin and soft tissue infections ranging from life-threatening endocarditis, chronic osteomyelitis, pneumonia, or bacteremia. From the emergence and application of antibiotics such as penicillin and methicillin in the middle of the last century, the eff...
