Abstract

During our continual investigations on Oldenlandia diffusa (Willd.) Roxb., two new iridoid glucosides, diffusosides C (1) and D (2), were isolated and their structures were elucidated through cumulative analysis of NMR and HRESIMS spectroscopic data as well as computational studies. Both isolated compounds displayed no obvious neuroprotective activity on H₂O₂-induced injury PC12 cells at 50 μM in vitro.

白花蛇舌草苷 C 和 D，两种新的环烯醚萜苷

摘要

在我们对白花蛇舌草(Willd.) Roxb.的持续研究过程中，分离出了两种新的环烯醚萜苷 C (1) 和 D (2)，并通过 NMR 和 HRESIMS 光谱数据的累积分析以及计算结果阐明了它们的结构。学习。两种分离的化合物在体外50μM对H ₂ O ₂损伤PC12细胞 没有明显的神经保护作用。
