Baicalein is one of the major flavonoids in Scutellaria baicalensis Georgi, which has long been used in several biological effects, such as antiviral, anti-inflammation, anti-hepatotoxicity, and anti-tumor properties, have been reported. In this study, baicalein demonstrated strong antibacterial activity against clinic isolated methicillin and vancomycin-resistant Staphylococcus aureus (MRSA and VRSA) in this experiment. Baicalein was determined against clinic isolated MRSA 1-16 with MIC and MBC values ranging from 64 to 256 and 64 to 512 μg/ml; for MSSA 1-2 from 128 and 256 μg/ml and 128 and 512 μg/ml; for VRSA 1-2 from 64 and 128 μg/ml and 64 and 512 μg/ml, respectively. The range of MIC50 and MIC90 of baicalein were 16-64 μg/ml and 64-256 μg/ml, respectively. The combination effects of baicalein with antibiotics were synergistic (FIC index <0.5) against most..
