Abstract Five new secoiridoid glycosides, cornusphenosides E-I (1–5), were isolated and characterized from an active fraction of ethanol extract of the fruits of Cornus officinalis. Their structures were determined by extensive spectroscopic data analysis, including 2 D NMR and HRESIMS experiments. In the preliminary assay, compound 5 (when evaluated at 10 μM) showed the neuroprotective effect against
摘要 从山茱萸果实的乙醇提取物的活性部分中分离和表征了五种新的secioridoid糖苷,cornusphenosides EI ( 1-5 )。它们的结构是通过广泛的光谱数据分析确定的,包括 2 D NMR 和 HRESIMS 实验。在初步测定中,化合物5 (当以10μM评估时 )显示出针对H 2 O 2诱导的SH-SY5Y细胞损伤的神经保护作用。
