Abstract

Twelve compounds were obtained by phytochemical investigation of 70% EtOH ( containing 0.5%NH3•H2O )extract of the roots of Bupleurum marginatum var. stenophyllum. Based on comparison of their spectral data, including HR-ESI-MS, ¹H-NMR, ¹³C-NMR data, with those of the literature, their structures were elucidated as saikosaponin b2 (1), saikosaponin a(2), saikosaponin b1(3), saikosaponin d (4), hydroxysaikosaponin a (5), saikosaponin b3 (6), saikosaponin c(7),saikosaponin i (8), saikosaponin f (9), chikusaikosides Ⅱ(10), saikosaponin s (11), and saikosaponin I(12). All compounds belong to olean-type triterpenoid saponin and compounds 1, 3, 5, 8-9,11, and 12 were isolated from this plant for the first time. At a concentration of 20 μmol•L⁻¹, compounds 2, 4, 6, 8, 11 and 12 showed strong inhibition activity against influenza virus WSN33 with the inhibition rate of 91.3%,88.6%,53.4%,61.3%,77.3% and 57.4%,respectively.

摘要

对窄叶柴胡根的70%乙醇（含0.5%氨水）提取物进行植物化学研究，得到了12种化合物。通过将它们的光谱数据，包括高分辨电喷雾电离质谱（HR-ESI-MS）、¹H-核磁共振（¹H-NMR）、¹³C-核磁共振（¹³C-NMR）数据与文献数据进行比较，确定它们的结构分别为柴胡皂苷b2（1）、柴胡皂苷a（2）、柴胡皂苷b1（3）、柴胡皂苷d（4）、羟基柴胡皂苷a（5）、柴胡皂苷b3（6）、柴胡皂苷c（7）、柴胡皂苷i（8）、柴胡皂苷f（9）、北柴胡皂苷Ⅱ（10）、柴胡皂苷s（11）和柴胡皂苷I（12）。所有化合物均属于齐墩果烷型三萜皂苷，化合物1、3、5、8 - 9、11和12首次从该植物中分离得到。在浓度为20 μmol•L⁻¹时，化合物2、4、6、8、11和12对流感病毒WSN33表现出较强的抑制活性，抑制率分别为91.3%、88.6%、53.4%、61.3%、77.3%和57.4%。
