A chemical investigation on 70% EtOH extract from the bark of Schneid (Rutaceae) led to six new methyl apiofuranosides (-), and ten known compounds (-). All these compounds were characterized by the basic analysis of the spectroscopic data including extensive 1D-, 2D-NMR (HSQC, HMBC), and high-resolution mass spectrometry, and the absolute configurations were determined by both empirical approaches and NOESY. Inhibitory effects of compounds - and - on nitric oxide production were investigated in lipopolysaccharide (LPS)-mediated RAW 264.7 cells, as a result, most of these isolates inhibited nitric oxide (NO) release, and among them , and displayed the strongest inhibition on NO release at the concentration of 12.5 μM.
对来自 Schneid(芸香科)树皮的 70%EtOH 提取物进行化学研究,分离得到了六个新的甲基阿比呋喃糖苷(-)和十个已知化合物(-)。所有这些化合物均通过包括广泛的 1D-NMR(HSQC、HMBC)和高分辨率质谱在内的光谱数据的基本分析进行了表征,并通过经验方法和 NOESY 确定了绝对构型。对化合物 - 和 - 在脂多糖 (LPS) 介导的 RAW 264.7 细胞中产生一氧化氮 (NO) 的抑制作用进行了研究,结果表明,这些分离物大部分均抑制了一氧化氮 (NO) 的释放,其中,和 对 NO 释放的抑制作用最强,在 12.5 μM 的浓度下。
