摘要：
The antimicrobial activities of longan (Dimocarpus longan Lour. Fen ke) seed extracts were investigated using a disc diffusion method and also determining the minimal inhibitory concentration. The DL-P01-SI01 fraction showed that the strongest activity against Staphylococcus aureus and methicillin-resistant S. aureus at MIC 64 mu g/mL, which was found to be due to the phenolic compounds. The HPLC analysis showed that the major phenolic compounds are gallic acid, corilagin, ethyl gallate and ellagic acid.
