The antibacterial activities of column chromatography fractions of n-hexane, benzene, chloroform, acetone, ethanol and water extracts from Acanthus ilicifolius were tested against 24 bacterial pathogens. The antibacterial activity was performed using agar diffusion method. Most active fractions were further investigated through UV-Vis, (13)C, (1)H-NMR, FT-IR for the structural elucidation. The antibacterial activity of the extracts was identified as 6-hydroxy-benzoxazolinone, (Z)-4-coumaric acid 4-O-β-D-glucopyranoside and 3,5-dimethoxy-4-hydroxy methyl benzoate.
采用琼脂扩散法测试了老鼠簕叶的正己烷、苯、氯仿、丙酮、乙醇和水提取物的柱层析部分对 24 种细菌病原体的抗菌活性。通过 UV-Vis、(13)C、(1)H-NMR、FT-IR 对具有活性的部分进行了结构鉴定，确定提取物的抗菌活性成分为 6-羟基苯并恶唑啉酮、(Z)-4-肉桂酸 4-O-β-D-吡喃葡萄糖苷和 3,5-二甲氧基-4-羟甲基苯甲酸酯。
