Three new C-methylated phenylpropanoid glycosides (1, 2), a new 8–4′-oxyneolignan (3), together with two known analogs (4, 5), were isolated from the rhizomes of Imperata cylindrical Beauv. var. major (Nees) C. E. Hubb. Their structures were determined by spectroscopic and chemical methods. Compounds 1, 2, and 5 (10 μM) exhibited pronounced hepatoprotective activity against N-acetyl-p-aminophenol (APAP)-induced
三个新的C-甲基苯丙苷(1,2),一个新的8-4'-oxyneolignan(3)中,用两个已知类似物(一起4,5),从根茎分离白茅Beauv。变种 主要(需要)CE Hubb。通过光谱和化学方法确定它们的结构。化合物1,2,和5(10μM)表现出显着的抗保肝活性ñ -乙酰基-对氨基苯酚(APAP)诱导的HepG 2细胞损伤的体外测定法。此外,它们对Fe 2+的抗氧化活性评估了半胱氨酸诱导的大鼠肝微粒体脂质过氧化作用以及脂多糖对鼠腹膜巨噬细胞(RAW264.7)中TNF-α分泌的影响。
