综合运用硅胶、凝胶Sephadex LH-20以及高效液相色谱分离方法对药食同源植物覆盆子果实的化学成分进行研究, 从中分离得到1个新的四氢化萘酚丁香酸酯rubusnolicester (1)、2个新的酚苷类衍生物2,6-二甲氧基-4-氯苯酚- 1-O-β-D-葡萄糖苷(2)和6'-乙酰基水杨酸-2-O-β-D-葡萄糖苷(3)、1个已知的水杨酸苷衍生物(4)以及3个黄酮类衍生物(5~7). 通过高分辨质谱、旋光以及核磁确定了它们的结构. 测试了所有化合物对脂多糖(LPS)诱导的小鼠巨噬细胞RAW264.7中NO释放的抑制作用, 化合物1显示出显著的NO生产抑制作用, 其IC50值为(12.28±1.25) μmol/L.

Silica gel column chromatography (CC), Sephadex LH-20 CC and high performance liquid chromatography (HPLC) were used to study the chemical constituents of the fruits of the medicine-food plant Rubus idaeus Linnaeus. A new tetrahydrogenated naphthol syringic acid ester, named rubusnolicester (1), two new phenolic glycoside derivatives, 4-chloro- 2,6-dimethoxylphenol-1-O-β-D-glucopyranoside (2) and salicylic acid-2-O-(6'-O-acetyl)-β-D-glucopyranoside (3), together with one known salicylic acid glycoside derivative (4) and three known flavonoids derivatives (5~7), were isolated. Their structures were elucidated by HRESI-MS, NMR spectroscopy, and a comparison of optical rotation (OR). Compounds 1~7 were evaluated the inhibitory activities against the nitric oxide (NO) production induced by lipopolysaccharide (LPS) in mouse macrophage RAW264.7 cells in vitro. Compound 1 exhibited inhibitory effect with the IC50 value of (12.28±1.25) μmol/L.
