Abstract
Two new iridoid glucosides, named diffusosides A and B, were isolated from the aerial part of Hedyotis diffusa Willd. Their structures were elucidated by 1D-, 2D-NMR spectroscopic analysis and HRESIMS. These two compounds showed no cytotoxic activity against SMMC-7721, SW480, SW620, Bel7402, and HepG2 cells.
摘要
从白花蛇舌草的地上部分分离得到了两个新的裂环环烯醚萜葡萄糖苷，分别命名为 diffusosides A 和 B。通过 1D、2D-NMR 光谱分析和 HRESIMS 确定了它们的结构。这两个化合物对 SMMC-7721、SW480、SW620、Bel7402 和 HepG2 细胞均无细胞毒性。
