A new compound, named coniferin B (), and fourteen known compounds were purified and identified from the leaves and branches of Meisn. Their chemical structures were elucidated through analyzing spectroscopic and HRESIMS data. Compounds , , , -, and were isolated from this plant for the first time. All compounds were assayed for cytotoxicity and activation of latent HIV activity on NH2 cells. The results showed that all compounds did not produce cytotoxicity at 10.0 μM and compounds , - showed weak activating activity with activation folds of 4.88, 7.14, 5.3, and 6.97, respectively.
从梅氏落叶松的枝叶中分离得到一个新的化合物，命名为 coniferin B ()，并鉴定了 14 个已知化合物。通过分析光谱和 HRESIMS 数据阐明了它们的化学结构。化合物 、 、 、 - 和 首次从该植物中分离得到。所有化合物均进行了 NH2 细胞的细胞毒性和潜伏 HIV 活性激活测试。结果表明，所有化合物在 10.0 μM 时均无细胞毒性，化合物 、 - 表现出较弱的激活活性，激活倍数分别为 4.88、7.14、5.3 和 6.97。
